| 摘 要： | 为深入探究城镇化对生态系统服务价值的驱动因素以及生态系统服务空间溢出效应,以山西省县域为研究单元,基于2000—2018年土地利用数据、社会经济数据构建生态系统服务价值和城镇化水平综合评价体系,通过双变量空间自相关分析县域城镇化与生态系统服务价值相关性的空间特征。结果表明:研究期间山西省生态系统服务价值整体呈下降趋势,城镇化综合水平虽有显著提高,但整体偏低。研究区城镇化和生态系统服务价值之间存在显著的负相关关系,呈"U"形发展趋势。空间计量模型结果表明,城镇化率、建成区面积与生态系统服务呈显著负相关,人均社会消费品零售总额、城镇化水平的平方项与生态系统服务呈显著正相关。生态系统服务价值对邻近县域产生正向的溢出效应,在控制其他解释变量不变的前提下,相邻县域生态价值每提高1%将对本县域产生0.243%的促进作用。研究区生态系统服务具有整体性和不稳定性,使各县域政府丧失自身环境保护的积极性。

| Abstract: | In order to deeply explore the driving factors of urbanization on ecosystem service value and the spatial spillover effect of ecosystem service, taking the county of Shanxi Province as the research unit, based on the land use data and socio-economic data from 2000 to 2018, constructs a comprehensive evaluation system of ecosystem service value and urbanization level, and analyzes the spatial characteristics of the correlation between urbanization and ecosystem service value through bivariate spatial autocorrelation, In addition, the spatial econometric model is used to explore the driving factors of urbanization on ecosystem service value and the spatial spillover effect of ecosystem service. The results showed that: During the study period, the ecosystem service value of Shanxi Province showed a downward trend as a whole, and the comprehensive level of urbanization was significantly improved, but the overall level was low. There is a significant negative correlation between urbanization and ecosystem service value in the study area, showing a U-shaped development trend. The results of spatial econometric model show that the urbanization rate, built-up area and ecosystem services are significantly negatively correlated, while the per capita retail sales of social consumer goods and the square of urbanization level are significantly positively correlated with ecosystem services. Ecosystem service value has a positive spillover effect on neighboring counties. Under the premise of controlling other explanatory variables unchanged, every 1% increase in the ecological value of neighboring counties will have a 0.243% promotion effect on the county. Ecosystem services in the study area are integrated and unstable, which makes the county governments lose their enthusiasm for environmental protection. |
