Ecological conservation red line (ECRL) is gaining increasing academic attention as delimiting the minimum space scope of ecological protection and the bottom line of ecological security. Taking Nanjing as a case study, we divided the territory into ecological and non-ecological redline areas (ERAs and NERAs, respectively). This paper highlights two key research issues based on the 2005, 2010, 2015 and 2018 annual remote sensing data: (i) quantitative analysis of the Ecological Redline Policy (ERP) validity by conducting a horizontal comparison of the ERAs and NERAs; and (ii) exploration of the land-use transitions and spatial pattern changes affecting ecosystem service value (ESV). Results showed that delineating ECRL could effectively slow down the decline rate of ESV. The trend of eco-quality deterioration was greater than eco-quality improvement in Nanjing, presenting an ESV that declined slightly in the whole. According to our findings, we suggest that reasonably increasing eco-lands (woodland and water area) and decreasing construction land will enhance the regional ESV. Meanwhile, promoting the transition from production space to ecological space and depressing the encroachment of living space on other space types, will be instrumental in mitigating the ESV decline. The results of this study are expected to provide valuable implications for spatial planning and sustainable development in Nanjing.

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.

Abstract Coal plays a crucial role in global economic development, which is still the most common and widely distributed fossil fuel in the world. As the world's largest developing country, China's mining and utilization of coal resources make great contributions to the rapid growth of China's economy. Inner Mongolia lies in the arid and semi-arid areas of China, its ecological environment is very fragile. The exploitation of opencast mining seriously hinders the sustainable use of regional land and the promotion of residents' well-being. This paper uses 2000, 2005, 2010, 2015 and 2020 remote sensing imageries, Based on ENVI, using a random forest algorithm to divide the land utilization type into construction land, vegetation, cultivated land, bare land and water area，and analyses the evolution characteristics of land use and ecosystem service value during the past 20 years. The results showed that: (1) Between 2000 and 2020, the construction land, vegetation and water of mining area were reduced, the bare land and cultivated land showed an increasing trend. The largest ratio changed is bare land, the smallest changed rate is water area. (2) The total ecosystem service value of the mining area reduced from10.939 billion yuan to 9.527 billion yuan. Among them, vegetation ecosystem service value is the highest, followed by cultivated land and water, and bare land ecosystem service value is the lowest. (3) From the spatial scale, the total ecosystem service value of the Shengli mining area decreases year by year, which shows that the land-use change in the mining area does have an impact on the ecosystem service value.

<p>Gannan forest is an important safety barrier in southeast China. In recent years, Ecological engineering such as Natural Forest Protection, Close Hillsides for Forestry and so on have been implemented in this area. But its ecosystem service value is in a decrease. Especially the soil erosion is serious. The analysis on the dynamic trend of water and soil conservation ecosystem service value and its formation mechanism is of big practical and theoretical significance. In our study, land use change is considered as entry point, while land use remote sensing data and spatial statistic data are used as our database. Logistic-CA-Markov complex model is constructed to predict the space-time evolution trend of forest land use under different circumstance. Based on the prediction, water and soil conservation ecosystem service value is evaluated using assessment approaches like shadow project approach and production cost method. Strategies to promote the ecosystem service are then put forward.</p>

Asset Value

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.

Since the beginning of the 21st century, urbanization has brought about dramatic changes in population, life, and economy, while having a significant impact on the distribution of ecosystem service. As research on the relationship between urbanization and ecosystem service has gradually specified, we decided to explore it at different scales. In this paper, we quantified and mapped the spatial–temporal evolution and relationship between urbanization and ecosystem service value in the Pearl River Delta Urban Agglomeration from 2000 to 2019 based on a dual-scale perspective of county and 3 km × 3 km raster. Our results show that the overall trend of urbanization level and ecosystem service value was increasing. Urbanization and ecosystem service value at the county scale showed a negative spatial correlation, while it was not significant at the raster scale. The “high–high” agglomeration was more concentrated, while the other three “low–low”, “low–high” and “high–low” agglomerations were more dispersed. Our findings suggest it is crucial to identify the key factors of small urban areas to grasp the development mechanism in the urbanization process and maintain the balance of the ecosystem.
