    摘要:

    为了解生态系统服务供需匹配、供需时空变化趋势及其影响因素。以山西省产水服务为切入点,基于1990年、2000年、2010年和2020年自然地理和社会统计数据,利用地理统计分析和InVEST模型,分析其供需时空变化特征。结果表明:(1)在产水服务供需时空格局方面,山西省产水服务供给与需求总量在30年呈增加趋势。山西东南地区(晋中市、长治市、晋城市)是主要的产水服务供给区;而产水服务需求较大的地区主要为太原、大同、长治和阳泉市区。(2)在产水服务供需匹配方面,1990-2000年产水服务供给不足的区域面积由1.82%急剧增加至16.80%,而在2010-2020年由16.95%急剧减少至5.34%,供需空间匹配状况有所好转。(3)通过空间自相关分析,山西省产水服务供给和需求之间存在明显空间不匹配。研究结果为全面梳理山西省生态系统服务供需匹配特征提供理论支撑。

    Abstract:

    To understand the match between supply and demand of ecosystem services, the spatial and temporal trends of supply and demand and their influencing factors. Using water production services in Shanxi Province as an entry point, and based on physical geography and social statistical data for 1990, 2000, 2010, and 2020, used geostatistical analysis and InVEST model to analyze the spatio-temporal changes characteristics of supply and demand. The results showed that: (1) In terms of the spatiotemporal patterns supply and demand for water production services in Shanxi Province showed an increasing trend over the 30-year period. The southeast region of Shanxi (Jinzhong, Changzhi and Jincheng cities) was the main supply area for water production services, while the areas with high demand for water production services were mainly the urban areas of Taiyuan, Datong, Changzhi and Yangquan. (2) In terms of matching the supply and demand of water production services, the area of regions undersupplied with water production services increased sharply from 1.82% to 16.80% in 1990 to 2000, while it decreased sharply from 16.95% to 5.34% in 2010 to 2020, with the spatial matching of supply and demand improving. (3) Through spatial autocorrelation analysis, there was an obvious spatial mismatch between the supply and demand of water production services in Shanxi Province. The research results provide theoretical support for comprehensively sorting out the supply and demand characteristics of ecosystem services in Shanxi Province.
