Spatial Divergence Analysis of Ecosystem Service Value in Hilly Mountainous Areas: A Case Study of Ruijin City

The southern hilly mountains are rich in natural resources and one of the important ecological security barrier zones China. However, disturbance ecosystem caused by human activities has led to a differentiated character spatial services. Such spatially characteristics have not been well studied, thus bound limit our ability manage ecosystems sustainably. Taking Ruijin City, typical mountainous area China, as an example, this paper evaluates service values (ESV) City from 2000 2020 using equivalent factor method combined with GIS technology. On basis, autocorrelation analysis is used identify unique heterogeneous units ESV. results show that overall ESV showed trend slow increase first decade significant decrease second decade. high degree divergence, showing distribution low value central region marginal region. With acceleration urbanization, decreases significantly 2010 2020. Therefore, for areas services, attention should be paid balanced development economy ecology. For low-value areas, it necessary strengthen control environment, protect sensitive serious loss change model, improve supply capacity products. government calculate green Gross Domestic Product (GDP) based on evaluation ESV, formulate GDP system performance evaluation.
