备注

剖析用地功能转变对某一特定区域生态系统服务价值变化的影响,是社会经济快速发展地区的国土开发和“三生”用地管理控制的主要依据。对“三生”用地识别缺失导致的复合功能模糊,以及与生态价值相关研究不足的问题,构建“三生”用地分类体系,采用生态服务当量因子法和GIS空间分析功能测算顺德区域内整体生态系统价值。结果 亚博app表明:(1)1990—2015年顺德区的“三生”用地经历了生活生产用地增长显著,生态生产用地面积变化较平缓,生产生态用地下降明显。(2)对顺德区生态系统服务价值(ESV)总额的提高贡献最大的是生态生产空间; 生态价值极低等级从东南部向全区扩散,极高等级从西部的聚集式面状分布变成点状分散式分布。(3)顺德区生态系统服务价值存在内部下降和上升的相互抵消作用,生态生产用地对生产生态用地的侵占能够提高区域内生态价值,因此保持生态生产用地中水库坑塘和河流的面积稳定对维持顺德区的生态系统服务价值具有至关重要的作用。

the analysis of the impact of land use function change on the change of ecosystem service value in a specific region is the main basis for land development and land management control of ecological-living-industrial land in the rapidly developing areas of social economy. with respect to the problem of ambiguity of compound function caused by the lack of identification of ecological-living-industrial land and the lack of research related to ecological value, a land classification system of the ecological-living-industrial land was constructed, and the ecological service equivalent factor method and gis spatial analysis function were used to calculate the overall ecosystem value in shunde region. the results showed that:(1)from 1990 to 2015, the ecological-living-industrial land in shunde district experienced significant growth of land for living and production, relatively flat change of land area for ecological production, and significant decline of land for production and ecological production;(2)the biggest contribution to the improvement of the total value of ecosystem services in shunde district is the ecological production space; the extremely low level of ecological value spreads from the southeast to the whole region, and the extremely high level changes from the concentrated planar distribution in the west to the dotted dispersed distribution;(3)ecosystem service value of shunde area exists inside falling and rising offset each other; that the ecological land for production occupies the production of ecological land can improve regional ecological value, thus maintaining the ecological land for production area to maintain the stable ponds, reservoirs and rivers has the vital role in ecosystem service value of shunde area.
