基于DPSIR-TOPSIS模型的陕北黄土高原农业生态系统健康评价
Agroecosystem Health Assessment of the Loess Plateau in Northern Shaanxi Based on DPSIR-TOPSIS Model
摘要
Abstract
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.关键词
