摘要
为评估云南省生态系统服务价值(ESV),分析其与经济增长的关系,采用2012、2015、2018、2021年数据对云南省ESV进行评价。结果显示:云南省ESV时间上微弱增长,空间上呈现滇中明显低于滇西的格局。基于此,采用非参数核回归模型拟合滇中、滇西北、滇西南研究区单位面积ESV与人均GDP的非线性关系,即生态库茨涅茨曲线。拟合结果均为N形,但各研究区进入N形曲线第2上升阶段的协同时间存在差异,滇西南最早,滇西北次之,而滇中尚未实现协同。结果表明:ESV发展趋同、ESV友好产业以及低生态成本有助于缩短研究区处在N形下降阶段的时间进而更早实现协同。
Evaluating ecosystem service value(ESV)and analyzing its relationship with economic growth can help to achieve collaborative development between ecological protection and economy.In this research,data collected in 2012,2015,2018 and 2021 were used to evaluate ESV in Yunnan Province,which showed a weak growth trend of ESV in Yunnan Province during the study period;and it also showed a spatial pattern of significantly lower ESV in central Yunnan than that in western Yunnan.Accordingly,a non-parametric kernel regression model was applied to fit the non-linear relationship between ESV per km 2 and GDP per capita in each study areas of central Yunnan,northwestern Yunnan,and southwestern Yunnan,i.e.,the Ecological Kuznets Curve.The model fitting results of three study areas were N-shaped,however,there was a difference in the time of synergy to enter the second ascending stage of the N-shaped curve,with the earliest in southwestern Yunnan,followed by northwestern Yunnan,while synergy had not yet been achieved in central Yunnan.In response to such difference,possible influencing factors were examined,with convergence of ESV development,ESV-friendly industries and low environmental costs contributing to a shorter period in the N-shaped decline phase in the study areas,and hence earlier synergies.
