摘要
如何定量评价土地利用总体规划实施的生态效应是十分值得关注的一个问题。本文从生态系统服务价值的角度对湛江市土地利用总体规划(1997～2010年)实施的生态效应进行定量评价。结果表明:1996～2005年,湛江市生态系统服务总价值从1996年的217.1214亿元增加至2005年的217.9867亿元,增加了0.8653亿元;耕地、林地、牧草地、居民点及工矿用地面的生态系统服务价值在减少,园地、水域和未利用地的生态系统服务价值在增加。2006～2010年,湛江市生态系统服务总价值进一步增加,但耕地、林地、居民点及工矿用地面的生态系统服务价值进一步减少。湛江市土地利用总体规划(1997～2010)的实施取得了一定的生态效应,但远远未达到规划预期目标。
It is a problem worthy of concern to how to evaluate quantitatively ecological effects of the implementation of comprehensive land use planning. This paper evaluates quantitatively ecological effects of the implementation of comprehensive land use planning （1997-2010） of Zhanjiang city from the viewpoint of ecosystem services value. The results suggest that from 1996 to 2005 the total ecosystem services value in Zhanjiang city increased by 0.865 3×10^8 Yuan from 217.121 4×10^8 Yuan in 1996 to 217.986 7×10^8 Yuan in 2005, and the ecosystem services value of cultivated land, forest land, grass land, residential and industrial land decreased, and the ecosystem services value of garden land, water land and unutilized land increased. From 2006 to 2010, the total ecosystem services value will further increases, but the ecological services value of cultivated land, forest land, forest land, residential and industrial land will further decreases. The implementation of comprehensive land use planning （1997-2010） of Zhanjiang city has taken some effects in ecosystem, but it is far below the planning target.
