摘要
基于当量因子法计算京津冀地区生态系统服务价值,构建生态系统服务价值与居民福祉协调性指数,结果如下:2000年-2018年,京津冀地区人均生态系统服务价值呈下降趋势,区域差异呈现先扩大再缓慢下降的趋势。京津冀地区人均生态系统服务价值空间分布差异明显。2000年-2018年,京津冀地区居民福祉呈上升趋势,区域差异在缩小,京津冀地区居民福祉空间分布差异不大。2000年-2018年京津冀地区生态系统服务价值与居民福祉呈现出不协调特征,总体上比较稳定。人口密度、人均耕地面积、人为影响指数、植被覆盖度和人均年收入是京津冀地区生态系统服务价值与居民福祉时空协调指数的主要驱动因子。
The ecosystem service value model is constructed by the improved equivalent factor method.The spatial analysis of ecosystem service value and residents well-being is carried out at the prefecture-level,and the coordination index of ecosystem service value and residents well-being is constructed.It is concluded that the per capita ecosystem service value in the Beijing-Tianjin-Hebei region showed a downward trend from 2000 to 2018.The regional differences showed a trend of first expanding and then slowly decreasing.The spatial distribution of per capita ecosystem service value in Beijing-Tianjin-Hebei region is obviously different.From 2000 to 2018,the residents well-being in the Beijing-Tianjin-Hebei region showed an upward trend,and the regional differences were narrowing.The spatial distribution of residentwell-being in the Beijing-Tianjin-Hebei region showed little difference.From 2000 to 2018,the value of ecosystem services and residents well-being in Beijing-Tianjin-Hebei region showed uncoordinated characteristics,and the residents well-being is much higher than the value of ecosystem services,and it is generally stable.Population density,per capita arable land area,human impact index,vegetation coverage and annual per capital incomeare the main driving factors for the spatio-temporal coordination index of ecosystem services value and human well-being in Beijing-Tianjin-Hebei region.
