Ecosystem Services Value

Based on parts of R. Costanzas results of ecosystem services value, this paper mainly discusses the calculative method for the value of natural ecosystem services. Appling some relative research and used substitution cost methods, prevented cost methods, shadow price methods, indirect market methods to estimate influences on constructive land ecosystem services in order to provided the basis for modification of atmosphere and climate and applying substitution cost methods to estimate the values of water regulation. By taking Taicang county in Jiangsu province as an application example, by identifying the functions of ecosystem services within this zone, and by calculating the value of ecosystem services through different years in the whole region , the annual tendency was then analysed. The results indicate that unmodified eco-service value represent theoretical levels of eco-service value, and can not show the changes of the ecosystem as a result of outside influences. But when the degree and size of influences on ecosystem by human activities on the constructional land are taken into account, and the eco-services values are considered as the results of original eco-service value plus outside influencing actions, the modified valuation methods for eco-service Values seem fairly suitable for the ecosystem itself and for the actual eco-service values shown by the ecosystem.

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.

Ecosystem Services Value

Ecological compensation standards and the allocation of compensation funds have always been the core issues of watershed ecological compensation. Due to the construction of the Eastern Route of the South-to-North Water Transfer Project (SNWTP), Jiangsu Province has paid a huge cost for the protection of water resources, and local economic development has been greatly affected. Therefore, this paper takes Jiangsu Province, the water source area of the Eastern Route of the SNWTP as an example, and combines a geographic information system (GIS) and remote sensing technology, using the ecosystem services value method to calculate the ecosystem services value of Jiangsu Province from 2005 to 2018. Then the change of this ecosystem services value in Jiangsu Province from 2015 to 2018 is taken as the basis for watershed ecological compensation standards of the Eastern Route. Through a compensation fund allocation model, watershed ecological compensation funds are allocated to four cities, Yangzhou, Huai’an, Suqian and Xuzhou, which are located along the Eastern Route of this SNWTP in Jiangsu Province. The results show that: (1) The ecosystem services value of Jiangsu Province has changed greatly. Urbanization and market environment of grain crops are the main reasons for this change; (2) the relationship between ecosystem services in Jiangsu Province is mainly synergistic; (3) Suqian receives US$24.73 million; Huai’an receives US$16.49 million; Yangzhou receives US$54.88 million and Xuzhou receives US$0.95 million in watershed ecological compensation, respectively. Watershed ecological compensation standards based upon the value of ecosystem services, and the allocation of compensation funds at the municipal level, are conducive to the improvement in efficiency of watershed ecological compensation in mainland China.

Ecosystem Services Value

Land-use/cover is one of the major factors that affect the ecosystem and the services it provides. The impact of land-use change on ecosystem service value is a hotspot in developing countries, especially China—a region with rapid economic development and rapid population growth. As the leading area of China’s reform and opening-up, Guangdong province in southern China is subjected to land-use conversion that significantly alters the capacity of natural ecosystem to provide ecosystem services supporting human well-being. We analyzed the characteristics of land-use changes from 1990 to 2018 using the four-phase land-use data interpreted from Landsat satellite images. We estimated the ecosystem service value through a well-established benefit transfer method using modified local value coefficients, analyzed the trade-offs and synergies among ecosystem services through ecosystem service trade-off degree, and compared the relationship between ecosystem services value, economic development, and population in Guangdong province. The results indicated that the following: (1) Built-Up Area drastically expanded from 6783.1 km2 in 1990 to 13,142.0 km2 in 2018 (93.7%), especially in the Pearl River Delta, where the growth rate of Built-Up Area expansion was up to 169.0%. The other land-use types were all contracted as Cropland (−10.9%), Forestland (−1.0%), Grassland (−4.0%), Water Body (−2.1%), and Unused Land (−24.4%). (2) Total ecosystem service value decreased from US$121,666 billion in 1990 to US$116,432 billion in 2018 (−4.3%). Cropland, Forestland, and Water Body played the most important roles for the total ecosystem service value. Water supply experienced the largest declines in ecosystem services value (US$ −1866.3 million, −10.1%), followed by waste treatment (7.6%) and gas regulation (−4.9%). (3) Synergy was the dominant relationship among ecosystem services. The above results can not only serve as reference case for other provinces/regions/countries/ to carry out relevant research work but also provide much focus on land-use planning to manage the impacts of land-use change on regional ecosystem services function.

The Impact

Increasing anthropogenic activities have significantly altered ecosystems in arid oasis regions. Estimating the impact on a wide range of ecosystem services is important for decision making and the sustainable development of these regions. This study analyzed time-series Landsat data to determine the influences of oasis land-use changes on the ecosystem services in the Kashgar region in Northwest China. The following results were found. The total value of the ecosystem services in the Kashgar region were approximately $10,845.3, $11,218.6, $10,291.7, and $10,127.3 million in 1986, 1996, 2005, and 2015, respectively. The water supply, waste treatment, biodiversity protection, and recreation and cultural services were the four ecosystem services with the highest service value, contributing 77.05% of the total ecosystem services. The combined contribution rate of food production and raw material value was only about 4.02%, relatively small. The sensitivity analysis indicated that the estimated total ecosystem service value (ESV) for this study area was relatively inelastic with respect to the value coefficients. The findings of this study will be crucial for maintaining the stability and sustainable development of the oasis region, where socio-economic development and the integrity of the natural ecosystem complement each other. Furthermore, the results provide a scientific basis for decision makers in land use management, and provide a reference for researchers in the Northwest China.

In this study, we applied gross ecosystem product (GEP) theory in a case study to analyze and explain the natural resource asset value and ecosystem service value of forest resources in Jiaokou County, Shanxi Province, Northern China, in 2018. GEP refers to the total value of various final material products and services provided by ecosystems. In this paper, six service functions of a forest system, including water conservation, soil conservation, carbon fixation and oxygen release, forest nutrients, purification of atmospheric environment, and biodiversity, are valued by three calculation methods: the alternative cost method, market value method, and control cost method. The study revealed the following: (1) There is a parallel relationship between the value of natural resource assets and the value of ecosystem services. GEP includes the market value of natural resource assets, but it is mostly the value of ecosystem services. (2) The measurement of the physical quantity of forest ecosystem services depends on parameter data, and the monetary calculation often has no mature pricing basis, which leads to the large scale and uncertainty surrounding the evaluation results of ecosystem services. (3) The ecosystem service value and natural resource asset value have different practical significance, as well as alternate theoretical bases. The value of natural resource assets can be used as the asset valuation basis of economic transactions, which plays a role in macroeconomic management. The value of ecosystem services can be used as the basis of ecological compensation, providing information for the preparation of the balance sheet of natural resources.
