Reservoir Basin

Being located in the northwest of Beijing, Guanting Reservoir has been an important source to supply water for life, production and landscape; however, with the increasing urbanization and population agglomeration in the upstream since 1980s, the resource and environment of Guanting Reservoir Basin was also undertaken an increasingly pressure accordingly with water quantity dropped and quality deteriorated, so Guanting Reservoir was ruled out of the drinking water supply system of Beijing since 1997. As a series of ecological protection and management project have been implemented with the 21st century coming, Guanting Reservoir restored its water-supply function for agriculture, ecology and industry in 2003, and restored its function as drinking water source in 2007, so it became an emergency water-supply source of Beijing again. The environmental protection status and economic development model of Guanting Reservoir Basin plays an essential role for water security of Beijing. In this paper, taken Guanting Reservoir Basin as the study case, the land use data of different periods since 1980s have been extracted from remote sensing images of the study area to analyze the land use changes. Based on the land use data, Costanza ecosystem service value formula and correction parameter suitable for China situations, the basin ecosystem service value is calculated to analyze the changes in leading ecosystem function of Guanting Reservoir Basin in different periods. In combination with the social and economic statistical data, the driving factors are discussed for changes in the leading function, and the approaches are put forward to enhance the upstream ecosystem function, so as to guarantee the sustainable economic and social development in the Basin. It is indicated from the research results that: (1) the driving forces for the changes in dominate ecosystem functions of Guanting Reservoir Basin mainly result from policy factor, population factor and economic factor; (2) the ecosystem services of Guanting Reservoir Basin are presented as asymmetric spatial characteristic; and (3) the eco-compensation mechanism is an important means to balance the asymmetry of ecosystem services between the upstream and downstream of Guanting Reservoir Basin and enhance the upstream capacity for provision of ecosystem services. The quantitative eco-compensation mechanism is the key point of follow-up research to enhance ecosystem services; the scenario analysis will have a prospective potential to propose some policy suggestions with more operability.

Land use changes significantly impacts ecosystem services and functions. The estimation of ecosystem services value is conducive to clarifying the ecological changes in response to LULC changes due to urbanization. Chengde was the upper water source of Beijing and Tianjin, the ecosystem is very fragile. After a series of ecology conservation projects like "returning cropland to forestry", the ecosystem service value increased from 5100.17 x 107 Yuan in 1990 to 5104.08 x 107 Yuan in 2008 respectively, with the average increase of 2.3 x 106 Yuan per year. It is indicated that ecosystem service value has the potential to inform policy decisions by emphasizing the benefits of sustainable ecosystem management. So plans on land use management should be made to maintain a balance between urbanization and ecosystem health.

The Impact

In order to evaluate the impact of land use change on ecosystem service value in Dujiangyan City, through equivalent factor method, qualitative and quantitative analysis is carried out on the dynamic change of land use change and its caused ecosystem service value in Dujiangyan City from 2010 to 2016. The results show that: (1) Dujiangyan city land use changes a large extent, with the extension of construction land expansion as the main increase part, and at the cost of the reduction of arable land and grassland area. (2) Over the past 7 years, the total value of ecosystem services in Dujiangyan city followed a law of first rising and then falling, showing an overall rising trend, with a total increase of 19.2244 million yuan. (3) The accuracy of the ecological value coefficient of woodland and grassland will greatly affect the value assessment of ecosystem services in Dujiangyan city. (4) From the relationship between land use type and ecosystem service value, cultivated land and construction land are negatively correlated with ecosystem service value, on the contrary, forest land, grassland, water area and construction land are positively correlated with ecosystem service value. In general, the land use of Dujiangyan City did not cause obvious damage to the ecological environment, but also cannot ignore the impact of land use changes on the environment in the process of economic development. It is necessary to control the growth of construction land area, promote the conservation and rational development of Eco-tourism area in Dujiangyan City, maintain the stability of ecosystem services in Dujiangyan City, and realize the strategy of sustainable development of Social-Economic-Ecological benefits.

In this study, we used long time series Landsat data and ecosystem services coefficients for global and Chinese ecosystems during 1978–2018 to estimate the influences of land-use change on ecosystem services (ES) in Kaidu–Kongque River Basin (KKRB), where both socioeconomic progress and the arid, fragile natural environment have considerable affected land-use change. The results showed that (1) the total value of ES in the KKRB was about USD 8111.5, 7995.31, 8275.74, 8131.91, and 8016.38 million in 1978, 1988, 1998, 2008, and 2018, respectively. The net ecosystem service value (ESV) loss was about USD 116.19 million for 1978–1988, the net ESV profit was about USD 280.43 million for 1988–1998, and the net ESV loss was about USD 259.36 million for 1998–2018. (2) Water supply and waste treatment function were the top two ecological functions with high service value; their combined contribution rate was 59.3%, indicating that the regulating service function in this study area is higher than the provision services function. (3) The high to low ranking for each ecosystem function based on their contribution rate to overall ES value was water supply > waste treatment > climate regulation > biodiversity protection > recreation and culture > soil formation > gas regulation > food production > raw material. These results are significant for the continuation of the integrity and sustainability of the mountain–oasis–desert region ecosystem, where socioeconomic progress and the fragile characteristics of the natural ecosystem complement each other. The results of this study provide scientific evidence for governmental decision makers and local residents and offer a reference for environmental researchers in northwest China.

The Impact

The evaluation of ecosystem service value has become the basis of ecological protection, ecological regionalization, and ecological compensations. Land use changes have taken place due to several natural and anthropogenic reasons, significantly influencing the ecosystem services value (ESV). In this study, we used an interactive coupling model that simulates future land use changes and the equivalent coefficient table method to predict and evaluate the ecosystem service value in the upstream of Xiong’an New Area in 2035, and we quantitatively calculated the impact of land use changes on the ecosystem service value under four future scenarios. The results indicate that from 2015 to 2035, the ecosystem service value in the production scenario and life scenario decreased significantly by CNY 1635.39 million and 561.95 million, respectively, and the areas where the ESV decreased mainly appeared in river banks and surrounding areas of towns. The conversion of forest land to cultivated land and the conversion of grassland to construction land are the main reasons for the reduction of the ecosystem service value in the production scenario and life scenario, respectively. The ecosystem service value in the ecological scenario increased significantly by CNY 2550.59 million, and the conversion of grassland to waters is the main reason for the increase in ecosystem service value, with a contribution rate of 73.89%. Moreover, due to the trade-off between ecosystem services, the overall change of ecosystem service value in the current scenario is not obvious. In conclusion, strictly controlling the scale of construction land, strengthening the management and protection of water resources, and expanding the afforestation scale may improve the ecosystem service value of the upstream Xiong’an New Area in the future.

Early Results

The high dam on the Occoquan River of Northern Virginia, United States of America, was constructed in 1957, forming a drinking water reservoir with a capacity of 37.1 × 106m3 formed by drainage from a 1 460 km2 watershed, and providing a safe yield of 189 251 m3 per day. Deteriorating water quality in the late 1960s led to a special “policy” for the watershed, designed to preserve the reservoir as a drinking water supply. Key provisions of the policy mandated replacement of the watershed's 11 publicly owned wastewater treatment works with a single advanced wastewater treatment plant (AWT), and establishment of the Occoquan Watershed Monitoring Programme. Early results from the programme established non-point nutrient pollution as a major cause of water quality deterioration and resulted in the implementation of non-point pollution controls throughout the watershed during the late 1970s. The AWT plant went on-line in July 1978. Continuous monitoring since 1973 has demonstrated both the necessity and the effectiveness of point and non-point nutrient controls for the preservation of the reservoir's water quality. The AWT plant provides excellent removal of organics and phosphorus, plus complete nitrification. The nitrates are discharged to the receiving stream to enhance conditions in the reservoir. Control policies include land-use management for the preservation of this essential water supply for 750 000 people in the Washington, D.C. suburbs. Land-use management decisions are based on the results obtained with a watershed-reservoir linked computer model which predicts water quality changes resulting from land-use changes.

Value Model

With the development of society, ecological environmental protection has become more and more important. In this paper, an Ecosystem Service Value Model (ESVM) was developed to quantify the value of all types of ecosystem services. Through the ecosystem service value evaluation index system we established, we determined ecosystem service value equivalent factors of different ecosystem services. Then we combine the baseline value of the ecosystem service value equivalent factor to determine the ecosystem service value per unit area of different ecosystems. The amount of ecological service value reduction can be calculated with the amount of change in ecosystem area caused by land use projects. Ecological costs are equal to the reduction in the value of ecosystem services. The true economic cost of land use project consists of two parts: project construction cost and ecological cost. The model established in this paper considers the effects of time changes. And the introduction of dynamic adjustment of biomass changes and dynamic adjustment of currency changes make the model more adaptable to time changes. The research can evaluate the value of ecosystem services, which promotes the harmonious development of human and ecological environment.

The Impact

Land use change has an impact on the ecosystem service value because it changes the structure and function of ecosystems. This paper analyzed the changes in land use during the period from 2000 to 2015 in Shangzhou district, and used the equivalent value of ecological services per unit area of land ecosystem combining the natural and economic conditions of Shangzhou district. Based on this method, the ecological service value of Shangzhou district was estimated, and the impact of land use change on the ecological service value was analyzed. The results showed that: (1) the main types of land use in Shangzhou district were grassland, woodland and farmland, among which the contribution rate of woodland to the value of local ecosystem services was the highest; (2) the overall trend in the ecosystem service value in Shangzhou district increased between 2000 and 2015, from 10.74 × 108 yuan in 2000 to 20.32 × 108 yuan in 2015, which is the result of the combined effects of regional economic development and changes in the natural environment and land use patterns; and (3) the main reason for the value increase of ecosystem services in Shangzhou district between 2000 and 2015 was that the grain-for-green policy transformed a considerable amount of farmland into woodland, while the main reasons for a decline in value was the expansion of built-up land that occupied other types of land.

The Impact

Urbanization-induced land-use change will lead to variations in the demand and supply of ecosystem services, thus significantly affecting regional ecosystem services. The continuous degradation of ecosystem functions has become a serious problem for humanity to solve. Therefore, quantitative analysis of the corresponding impact of land-use change on ecosystem service value (ESV) is important to socio-economic development and ecological protection. The Anhui province in China has experienced rapid urbanization in recent years, and ecological environmental remediation and protection have become important goals for regional development. In this paper, the province of Anhui has been selected as a case of study, we analyzed the land-use change using Landsat images from 2000, 2005, 2010, and 2015. We then adjusted the equivalent factor of ESV per unit area and estimated the ESV of Anhui province from 2000 to 2015 to analyze the impact of land-use change on ESV. Our results show that (1) paddy field is the main land-use type in Anhui province, the built-up land area has continuously increased, and the water area has continuously decreased; (2) the total ESV of Anhui province decreased from 30,015.58 × 107 CNY in 2000 to 29,683.74 × 107 CNY in 2015 (the rate of change was −1.11%), and regulating services make the greatest contribution to ESV; and (3) land-use change has led to severe ESV variations, especially for the expansion of water area and built-up land. Our study results provide useful insights for the development of land-use management and environmental protection policies in Anhui province.

Based on the data of land use in 1999, 2005, 2010 and 2020, selected the typical tourist area Yangshuo and research the land use changes on ecosystem service value and then estimated the value change. Throughout the study period, Yangshuo County has been always implement tourism development strategy, the unused land substantially reduced and transformed into woodland, water body and wetland, which makes the ecological environment has been improved. The total value of ecosystem services in Yangshuo County was 1067.4 million Yuan in 1999, 1165 million Yuan in 2005, 1478.3 million Yuan in 2010, from 1999 to 2020, the ecosystem service values increased 1002.9 million Yuan, it is mainly due to the increasing areas of woodland, water body and wetland. The combined ecosystem service value of woodland and cropland was about 90% of the total value. The contribution of each ecosystem function to the overall ESV was greatest for soil formation and retention, followed by water supply, both of them contributing about 34% of the total value. Yangshuo County implement eco-tourism, landscape of leisure tourism and agro-tourism as the development strategy, it provides a strong protection to protect the local environment, and promote the ecosystem service values on the rise.
