摘　　要：太行山区由于受人类活动的影响,在过去的几十年内众多小流域土地利用结构产生了很大的变化,进而影响了小流域生产、生活、生态的“三生”用地结构、生态系统服务和山区农户生计。本文以洞阳坡小流域作为太行山中山区代表,通过对当量因子法系数的修正,对2000—2020年“三生”用地结构变化及其生态系统服务价值进行了评估,并以人工种植面积最大且为本地优势树种的连翘为例,进一步调研分析了“三生”用地结构变化对农户生计的影响。研究结果表明:1)20年来洞阳坡小流域“三生”用地结构比例基本保持不变,呈现出生态用地>生产用地>生活用地。但“三生”用地中生态用地内部的土地利用方式发生了变化,具体表现为人为作用下,当地优势树种连翘种植面积显著增加。2)20年来洞阳坡小流域内生态系统服务价值提高了1528万元,其主要原因是生态用地中大量草地转化为以种植连翘为主的林地,林地生态系统服务的提高对生态系统总服务提高的贡献率为99.95%。3)20年来,连翘林地供给服务的增加占小流域供给服务增加的43.05%,占小流域生态系统总服务增加的28.02%,连翘林地生态系统服务供给效益的提高增加了洞阳坡小流域的农户收入,使得小流域农户生计水平有所改善,连翘种植带来的“三生”用地变化对农户收入来源结构起到了优化调整的作用。本研究可为太行山区的生态经济协同发展提供一定的理论依据。Due to the influence of human activities on Taihang Mountain area,the land use structure of numerous small watersheds has undergone significant changes over the past few decades,which in turn affects the“Production-Living-Ecological”land use structure,ecosystem services,and the livelihood of mountain farmers in small watersheds.The Dongyangpo watershed is a typical transitional geographical space in the transition from the subalpine area to the hilly area of Taihang Mountain area.This study aimed to systematically study the impact of“Production-Living-Ecological”land use change on ecosystem services and farmers’livelihoods in small mountain watersheds.Taking the Dongyangpo watershed,a typical small watershed in Taihang Mountain area,as an example,this study evaluated the structure change and ecosystem service values of“Production-Living-Ecological”land from 2000 to 2020 by modifying the coefficient of equivalent factor method in combination with the actual situation of the small watershed,and further investigated and analyzed the impact of the land structure change of“Production-Living-Ecological”on farmers’livelihood by considering Forsythia suspensa,which has the largest artificial planting area.The research results showed that,first,over the past 20 years,the“Production-Living-Ecological”land structure in the Dongyangpo watershed had remained basically unchanged,showing ecological land>production land>living land.However,the land use mode within the ecological land had changed,which was specifically reflected in the significant increase in the planting area of F.suspense,the local dominant tree species,and reduction in grassland areas.Second,the ecological land in the Dongyangpo watershed contributed the most to the total ecosystem services,and the total ecosystem services value in each period accounted for more than 99%of the total.Third,over the past 20 years,the ecosystem service value had increased significantly,with an increase of 146.89%.The main reason for this was a large portio
