城市区域开发对生态系统服务功能影响评价--以东莞市为例

摘要

以东莞市为例，运用环境经济学方法对＂十一五＂期间城市区域开发对生态系统服务功能的影响进行评价。2011年东莞市生态系统服务功能总价值约为25．44亿元，较2005年（31．20亿元）减少18．5％。气体调节、气候调节、水源涵养等9种生态系统服务功能价值均有不同程度的减少，其中水源涵养、废物处理和休闲娱乐3种生态系统服务功能的价值减少均超过20％。结果表明，东莞城市建设已经对区域生态系统服务功能造成了较大的影响，土地利用方式有待进一步优化。%Take Dongguan City as an example , using the method of environmental economic , the impact of urban regional development on ecosystem services in "Eleventh Five-Year"period is assessed.In Dongguan, the total value of ecosystem services decreased from RMB 3.120 billion in 2005 to RMB 2.544 billion in 2011.Nine indices including gas regulation , climate regulation, water conservation and so on all decreased in single service function of ecosystem , among which , water conservation , waste treatment and leisure entertainment reduced more than 20%.The results showed that the continuous progress of urbanization in Dongguan has resulted in great impact on regional ecosys -tem services, and the pattern of land use needs to be further optimized .
