生态服务价值空间异质性及生态功能区划探析

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

  • 摘要: 估算了中山市20002010年的生态系统服务价值变化并以中山市2000、2005、2010年的节点TM遥感影像为基础数据源,借助相关辅助资料,利用RS、GIS和SPSS等技术方法分析生态服务价值的空间异质性,引入变异系数和相关系数探讨了生态服务价值时序变化与各生态系统类型变化之间的关系. 在此基础上,以生态系统服务价值估算结果为重要生态指标,结合植被、地形、景观生态类型等构建指标体系,对中山市的生态系统服务功能进行区划。以生态建设为目标将中山市生态功能区划分为生态保育区、生态控制区和生态协调区三大功能区,明确了各功能区的主导生态功能,为中山市今后各生态服务功能区建设规划提供参考.

     

    Abstract: 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.
