摘　　要：探索生态系统服务间权衡协同关系及其影响因素对实现区域人与自然和谐发展具有重要意义。本研究以长株潭都市圈为例,揭示了2000―2020年的粮食生产、碳储量、生境质量和土壤保持4类生态系统服务的时空演化及权衡协同关系;引入人类活动强度指数,综合自然和人为因素,并运用地理探测模型遴选出了不同年份生态系统服务权衡协同的主要影响因素。结果表明:1)2000―2020年,长株潭都市圈内粮食生产呈上升趋势,其余3类服务均呈下降趋势。其中,粮食生产高值区主要集中在长株潭西南部;碳储量、生境质量与土壤保持量高值区主要在东北部。2)2000―2020年,生境质量、碳储量与土壤保持量间3组关系均呈协同,其他均呈权衡关系。3)单因子探测结果中,2000年和2020年高程对6组权衡协同关系均有较大影响;其次为年均降雨量。4)交互因子探测结果中,2000年高程与年均降雨量影响显著;2020年高程与人均生产总值作用影响显著。Exploring the trade-offs and synergies among ecosystem services and their influencing factors is of great significance for promoting harmony between human and nature.Taking the Changsha-Zhuzhou-Xiangtan metropolitan area as an example,this study revealed the spatiotemporal evolution and the trade-off and synergy relationships of four types of ecosystem services,namely food production,carbon storage,habitat quality,and soil conservation,from 2000 to 2020.The Human Activity Intensity Index was introduced to integrate natural and human factors,and the Geodetector was applied to select the main influencing factors of the trades-offs and synergies of ecosystem services in different years.The results indicate the following:1)From 2000 to 2020,food production in the Changsha-Zhuzhou-Xiangtan metropolitan area showed an upward trend,while the other three types of services all showed a downward trend.Specifically,high-value areas of food production were mainly concentrated in the southwestern part of the metropolitan area,and high-value areas of carbon storage,habitat quality,and soil conservation were mainly in the northeastern part.2)There were synergistic relationships among the three pairs of relationships between habitat quality,carbon storage,and soil conservation,while the other relationships were all characterized by trade-offs.3)Single-factor analysis revealed that elevation was the dominant factor influencing the six pairs of trade-off and synergy relationships in both 2000 and 2020,followed by average annual rainfall.4)Interaction analysis showed that elevation and average annual rainfall were the most significant influencing factors in 2000,while elevation and per capita GDP played a greater role in 2020.
