生态优先视域下资源诅咒空间分异分析——以黄河流域为例

Spatial Distribution Analysis of Resource Curse Based on Ecological Priority——A Case Study of the Yellow River Basin

综合运用ESDA分析框架对黄河流域内各省水足迹、GDP空间分异进行分析,研究结果表明:流域尺度上,黄河流域水资源诅咒现象存在显著的空间分异;区域尺度上,虚拟水贸易是影响水资源供需平衡的关键要素,水足迹存在显著空间分异;省域尺度上,强、中资源诅咒区省份种植结构的虚拟水含量较高,弱资源诅咒区省份种植结构的虚拟水含量较低;黄河流域各省水足迹和GDP空间分布趋同,均在下游弱资源诅咒区高值集聚,上游强资源诅咒区低值集聚。

This paper analyzes the spatial distribution characteristics of water footprint and GDP in the Yellow River Basin by ESDA analysis framework.Results show that,firstly,in the basin scale,there are significant spatial distribution of water resource curse in the Yellow River Basin.Secondly,'in the regional scale,the vitual water trade is the key factor influencing the balance of water supply-demand and the water footprint has obvious spatial distribution characteristics.Thirdly,in the provincial scale,there is higher content of virtual water of planting structure in the strong and medium resource curse area and lower content in the weak resource curse area.Fourthly,there is the same spatial distribution of water footprint and GDP in the Yellow River Basin.The higher values of water footprint and GDP concentrate in the downstream area,which is weak resource curse area.
