基于土地整理的生态服务价值损益估算——以洪江市洗马乡土地整理项目为例

摘要

以洪江市洗马乡土地整理项目为例,根据该项目整理前后的数据,利用Costanza的生态系统服务价值计算公式,参考中国陆地生态系统单位面积服务价值,研究了洗马乡土地整理前后土地利用变化对生态系统服务价值的影响.结果表明,洗马乡土地整理项目在整理前后生态服务价值减少了32.24万元,下降了7.3％.%Using Costanza calculation equation of ecosystem service value and considering terrestrial ecosystem service value per unit area in China, the influences of land use changes on ecological service values before and after land consolidation in Xima town were studied according to the data before and after land consolidation project in Xima town of Hongjiang city.The results showed that the ecosystem service values of Xima town decreased 32.24×104 yuan after land consolidation, and the descending ratio was 7.3%.
