摘　　要：为掌握陕西湿地生态系统健康状况,运用P-S-R模型,以人口密度、区域开发指数、万元GDP耗水量、化肥施用强度等17个指标构建指标体系,采用层次分析法确定各指标权重,利用物元模型对陕西湿地生态系统健康状况进行评价。结果表明,Ⅲ类以上河流水质、降雨量、自然湿地率和人口密度是影响湿地生态系统健康状况的最重要因素。西安、咸阳、渭南3市综合评价等级为亚健康,铜川、宝鸡、延安、榆林、商洛5市综合评价等级为健康,汉中、安康2市综合评价等级为很健康。In order to grasp the health status of wetland ecosystem in Shaanxi Province,the P-S-R model was used to construct an index system with 17 indicators such as population density,regional development index,water consumption per ten thousand yuan GDP,fertilizer application intensity,etc.The weight of each index was determined by analytic hierarchy process,and the health status of wetland ecosystem in Shaanxi Province was evaluated by matter-element model.The results showed that water quality,rainfall,natural wetland rate and population density were the most important factors affecting the health status of wetland ecosystems.The comprehensive evaluation grades of Xi'an,Xianyang and Weinan were sub-health,the comprehensive evaluation grades of Tongchuan,Baoji,Yan'an,Yulin and Shangluo were healthy,and the comprehensive evaluation grades of Hanzhong and Ankang were very healthy.
