摘　　要：针对城市快速发展给生态环境带来的压力问题,对陕西省城市生态系统健康评价进行了相关研究。根据城市生态系统健康的内涵及数据的可获得性,从活力、组织力、恢复力、生态系统服务功能和人类健康状况方面构建了健康评价指标体系,确定了健康评价标准。采用层次分析法确定指标权重,进而对该省2013-2017年省域层面城市生态系统健康状况进行动态评价。研究表明,活力与组织结构两要素对生态系统健康有较大贡献,生态系统服务功能随着时间推移在不断提高,自然结构和垃圾处理能力是当前胁迫生态系统健康的主要因素。总体而言陕西省城市生态系统健康水平呈现逐年上升趋势,未来仍有较大的发展潜力和提升空间。In view of the pressure brought by the rapid development of the city to the ecological environment, relevant research was carried out on the evaluation of urban ecosystem health in Shaanxi Province. According to the connotation of urban ecosystem health and the availability of data, this paper established a health evaluation index system from the aspects of vitality, organization, resilience, ecosystem service function and human health status, and determined the health evaluation criteria. The analytic hierarchy process is used to determine the weight of the indicators, and then the dynamic evaluation of the urban ecosystem health status at the provincial level in 2013-2017 is carried out. The result showed that both vitality and organizational structure contribute to ecosystem health. Ecosystem service functions are constantly improving over time. Natural structure and waste disposal capacity are the main factors that hinder ecosystem health. In general, the health level of urban ecosystems in Shaanxi Province is increasing year by year, and there is still a large potential for development and room for improvement in the future.
