摘要
为认识我国水资源可持续性和生态系统服务的变化特征,并揭示两者之间的关系,采用水资源可持续性评价模型和生态系统服务价值量化模型,分析了我国省域水资源可持续性和生态系统服务价值的时空变化特征,并结合耦合协调度模型进一步探讨了我国水资源可持续性与生态系统服务的耦合协调关系。结果表明:2008—2018年,我国各省域的水资源可持续性时间变化不明显,可持续性水平仍有较大提升空间,较高及高水平水资源可持续性的省域主要是东部沿海省份和西藏,中等及以下水平水资源可持续性的省域主要位于长江和黄河流域的中上游地区、西北及东北地区。2010—2018年,我国生态系统服务的供给能力在减弱,高价值和较高价值的省域主要位于中南部地区和东北地区,低价值省域主要为新疆和甘肃。2010—2018年我国省域水资源可持续性与生态系统服务之间的耦合协调度先减小后增大,整体处于初级协调类型,大致呈现自东南向西北递减的空间分布格局。
In order to understand the variation characteristics of water resources sustainability and ecosystem services in China,and reveal the relationship between the two,the water resources sustainability evaluation model and ecosystem services value quantification model were integrated to analyze the spatial and temporal variation characteristics of water resources sustainability and ecosystem services values in Chi⁃na’s provinces.Then the coupling coordination degree model was used to further explore the coupling coordination relationship between water resources sustainability and ecosystem services values.The results show that the temporal variation of water resources sustainability in China’s provinces is not obvious from 2008 to 2018,and the sustainability level has room for improvement.The provinces with high and higher levels of water resources sustainability are mainly located in the eastern coastal region and Tibet,and the provinces with medium and lower levels of water resources sustainability are mainly located in the middle and upper reaches of the Yangtze and Yellow River basins,Xinjiang,and the northeast region of China.From 2010 to 2018,the supply capacity of ecosystem services in China is weakening.The high⁃value and higher⁃value provinces of ecosystem services values are mainly located in the south central region and the northeastern region of China,and the low⁃value provinces of ecosystem services values are mainly Xinjiang and Gansu.From 2010 to 2018,the coupling coordination degree between water resources sustainability and ecosystem services in China’s provinces first decreases and then increases,and the overall coordination type is in the primary coordination type,showing a spatial distribution pattern of decreasing from southeast to northwest.
