摘　　要：为刻画近20年石羊河流域生态系统服务价值演化格局,揭示流域生态与经济协调发展特征,选取石羊河流域9个县(区)为基本研究单元,在分析流域内主要行政单元近20年社会经济发展现状、评估流域生态服务价值的变化基础上,通过构建生态与经济耦合协调度评估模型,揭示过去20年流域内经济发展与生态保护间的耦合特征及时空演变规律,利用回归模型分析影响二者耦合协调度变动的因素,以期为流域可持续发展和生态恢复治理提供参考。结果表明:(1)2000—2019年石羊河流域生态服务价值增长趋势明显,县(区)间差异显著。(2)研究期间生态经济耦合协调度呈波动增加的趋势,“十一五”发展期间是其重要变化时间段,2009年是影响耦合协调度由波动下降转为缓慢上升的关键年份;从空间维度来看,“协调”县(区)大多集中在流域上游,“不协调”县(区)多集中在流域下游;上游地区耦合协调度整体优于下游地区。(3)农村居民人均可支配收入、城镇化率、同比例环境等公共设施从业人员是影响流域生态与经济耦合协调度的重要人为因素,此外,县(区)空间位置也是影响结果差异的实际伴随因素。未来应根据区域上下游实际情况,通过人类活动积极克服地区自然禀赋差异,制定适合本地区的特色发展战略并及时落实,以实现生态与经济协调发展。In order to describe the evolution pattern of ecosystem service value in Shiyang River Basin in recent twenty years and reveal the characteristics of coordinated development of ecology and economy in this basin,nine counties(districts)in Shiyang River Basin are selected as basic research units.Based on the analysis of the current situation of social and economic development of the main administrative units in the basin in the past twenty years and the evaluation of the changes in the value of ecological services in the basin,an evaluation model of ecological-economic coupling coordination index is constructed.This paper reveals the coupling characteristics and spatio-temporal evolution patterns between economic development and ecological protection in the basin in the past 20 years,and analyzes the factors affecting the change of the coupling coordination index by using the regression model,so as to provide reference for the sustainable development and ecological restoration of the basin.The results show that:(1)from 2000 to 2019,the ecological service value growth trend of Shiyang River Basin was obvious,and the difference between counties(districts)was significant.(2)During the research period,the ecological-economic coupling coordination index showed a trend of increase with fluctuation,and from the research,it could be revealed that the"Eleventh Five Year Plan"development period was an important change period,and that 2009 was the key year that affected the coupling coordination index from declining fluctuation to slowly rising.From the perspective of spatial dimension,"coordinated"counties(districts)are mostly concentrated in the upper reaches of the basin,while"uncoordinated"counties(districts)are mostly concentrated in the lower reaches.And the coupling coordination index of the upper reaches is better than that of the lower reaches as a whole.(3)Rural residents'per capita disposable income,urbanization rate,public facilities employees in the same proportion of environment and others are important human fa
