Analysis on Spatial Heterogeneity of Ecosystem Services Value and Ecological Function Regionalization of Zhongshan City

The changes of ecosystem service value between 2000 to 2010 in Zhongshan is estimated. Zhongshan remote sensing images in 2000, 2005, and 2010 are used to analyze the spatial heterogeneity of ecosystem service value by RS, GIS, SPSS, and other technical methods with the help of relevant data. Furthermore, the variation coefficient and correlation coefficient are used to explore the relationship between the temporal change of ecological service value and the change of ecosystem types. Index system is constructed by taking the estimation of ecosystem service value as an important ecological indicator and combining with the vegetation, topography, and landscape ecological type. On the basis of this index system, ecosystem service functions are zoned in Zhongshan. The ecological functional area in Zhongshan is divided into three major functional areas: ecological conservation area, ecological control area, and ecological coordination area so that the dominant ecological functions of each functional area is cleared by taking the ecological construction as the goal. Those will provide a reference for the future planning of various ecological service functional areas of construction in Zhongshan City.
