草原生态恢复工程下新疆草原植被覆盖动态及其对生态系统服务的约束效应
Shuitu Baochi Xuebao目的探索大型生态工程对草原植被覆盖动态的影响，阐明植被变化对生态系统服务的约束效应，为区域可持续发展和生态恢复工程的改进提供可靠的科学依据。方法以地处干旱地带的新疆地区为例，采用趋势分析法，探析生态恢复工程对植被覆盖的影响，基于InVEST模型和CASA模型，评估其产水量、碳储存、土壤保持和净初级生产力（NPP）4种草原生态系统服务，揭示生态恢复工程下植被覆盖对4种草原生态系统服务的约束效应。结果1）在生态恢复工程驱动下，有79.2%的区域草原归一化植被指数（NDVI）残差为正值 ...
