摘要
目的:对喀斯特地区不同类型不同区域土地整治所引起的生态系统服务价值变化规律进行研究。方法:采用谢高地生态系统服务价值当量法测算典型案例在实施土地整治前后生态系统服务价值及其变化,分析生态系统服务价值对土地整治类型和区域的响应规律。结果:(1)生态系统服务价值对4类土地整治项目的响应差异较为显著,农村建设用地整理较高,其次为农用地整理与土地复垦,宜耕后备土地资源开发最低。(2)各类土地整治对生态系统服务价值影响存在地区差异。(3)单位建设规模生态系统服务价值和投资生态系统服务价值系数2个指标在地区和类型间存在差异,农用地整理和土地复垦的2个指标地区差异不显著,而宜耕后备土地资源开发和农村建设用地整理的2个指标地区差异显著。结论:生态系统服务价值法在土地整治生态效益评价中具有广阔的应用前景。
In this study we analyzed the change rules of ecosystem service value caused by land consolidation of different types in different regions in karst area.XIE Gaodi’s method of equivalents of ecosystem service value was employed to estimate the ecosystem service value and its changes before and after land consolidation in typical cases.The results showed that:(1)the response of ecosystem service value to the four types of land consolidation projects was different,and was in the order of rural construction>farmland consolidation>land reclamation>reserved land resources;(2)the response of ecosystem service value to land consolidation had regional differences;(3)the ecosystem service value per construction unit and the investment coefficient of ecosystem service value were different between regions and land consolidation types.The 2 indexes of farmland consolidation and land reclamation had little regional differences,while the 2 indexes of reserved land resources and rural construction land had obvious regional differences.The ecosystem service value response method had broad application prospect in the evaluation of ecological benefit of land consolidation.
