黄河流域生态功能区植被NPP时空变化分析及驱动因素
Analysis of spatial and temporal variation of vegetation NPP in the ecological functional area of the Yellow River Basin and its driving elements
黄河流域在中国经济社会发展和生态安全方面都具有十分重要的地位,基于中国生态系统评估与生态安全数据库将黄河流域划分为 11个生态功能区,以MOD17A3HGF V6植被净初级生产力(NPP)数据为基础,采用Sen+MK趋势分析、变异系数(Cv)、莫兰(Moran's I)指数、Mann-Kendall突变检验方法对黄河流域 2001-2020年NPP时间序列变化和空间分布规律进行分析。结果表明:(1)黄河流域植被净初级生产力(NPP)在 2001-…查看全部>>
The Yellow River Basin is very important in China's economic and social development and ecological security.Based on the China Ecosystem Assessment and Ecological Security Database,the Yellow River Basin was divided into 11 ecological functional zones,and based on the MOD17A3HGF V6 vegetation Net Primary Productivity(NPP)data,the time-series changes of the NPP in the Yellow River Basin and its spatial distribution pattern from 2001 to 2020 were analyzed by u…查看全部>>
