摘　　要：陕北黄土高原生态环境脆弱,基于驱动力-压力-状态-影响-响应(DPSIR)模型,构建陕北黄土高原榆林市和延安市农业生态系统健康评价指标体系,采用逼近理想解排序法(TOPSIS)评价农业生态系统健康状况,并利用障碍因子诊断模型确定影响陕北黄土高原农业生态系统健康发展的主要障碍因子,结果表明:2012—2021年陕北黄土高原农业生态系统健康状况整体转好,其中榆林市健康等级由Ⅳ级提升至Ⅱ级,延安市健康等级由Ⅳ级提升至Ⅲ级;子系统中榆林市压力子系统指数、延安市状态子系统指数均呈下降趋势,两市驱动力子系统指数、响应子系统指数均呈上升趋势;人口因素、自然条件和传统农业生产模式是影响陕北黄土高原农业生态系统健康状况的主要因子。The ecological environment of the Loess Plateau in northern Shaanxi is fragile.In this study,we built an agroecosystem health evalu⁃ation index system based on the Driving Force⁃Pressure⁃State⁃Impact⁃Response(DPSIR)model for Yulin and Yan’an cities in the Loess Plat⁃eau of northern Shaanxi,and evaluated the agroecosystem health status by using the method of approximating the ideal solution ranking(TOP⁃SIS),which was a method for assessing the health status of agroecosystems,and to identify the main obstacle factors affecting the healthy devel⁃opment of agroecosystems in the Loess Plateau of northern Shaanxi by using a diagnostic model of obstacle factors.The results show that the overall health status of agroecosystems in the Loess Plateau of northern Shaanxi have turned better from 2012 to 2021,in which the system health grade of Yulin City is improved from GradeⅣto GradeⅡ,and that of Yan’an City is improved from GradeⅣto GradeⅢ.Among the subsystems,the pressure system index of Yulin and the state system index of Yan’an show a downward trend,and the index of the driving force subsystem and the index of the response subsystem show an upward trend.Population factors,natural conditions and traditional agricultural pro⁃duction models are the main factors affecting the health status of agroecosystems in the Loess Plateau of northern Shaanxi.
