中文摘要	土地利用和自2008年以来的石漠化综合治理工程(RDCP)使得中国西南地区发生了重大的土地利用/覆盖变化(LUCC),量化LUCC对生态系统生产力的影响对于评估生态恢复工程的效益十分重要。本研究用MODIS土地覆盖和净初级生产力(NPP)产品,评估了2008-2013年环江县(首批实施RDCP的百县之一)LUCC对NPP的相对贡献。研究发现,全县95.53%地区的NPP有所增加,其中非石漠化地区NPP的平均增长高于石漠化/潜在石漠化地区。LUCC对全县NPP的增加贡献了25.23%,在LUCC区域的贡献非常突出(70.97%),分别使NPP增加了3.9% 和10.5%。在该县的6个RDCP区域,经过治理的植被恢复区域的NPP平均增幅显著高于其邻近未治理的喀斯特区域,并且增幅随植被恢复措施实施面积的增加而增加。
英文摘要	Karst areas in southwest China have experienced significant land cover and land use change (LUCC) due to utilization for human activity and a comprehensive rocky desertification control project (RDCP) since 2008.It is important to quantify the effect of LUCC on ecosystem productivity in this region for assessing the overall benefit of this ecological restoration project.In this study,we used using MODIS land cover and NPP products to investigate the relative contribution of LUCC to the change in net primary productivity (NPP) during 2008-2013 in Huanjiang County,one of first one hundred pilot counties to implement RDCP.Our results show that NPP increased in 95.53% of the county,and the average growth of NPP in non-rocky desertification area was higher than in rocky desertification or potential rocky desertification areas.LUCC has an important contribution (25.23%) to the NPP increase in the county,especially in the LUCC area (70.97%),which increased the average NPP by 3.9% and 10.5%,respectively.Across the six RDCP regions in the county,the average increase in NPP for the vegetation restoration measure of governed karst area is significantly greater than in the ungoverned karst area,and the positive change in NPP increased with the increasing implementation area of the vegetation restoration measure.
