摘　　要：文章基于2012年-2021年的时间序列数据,选用DPSR评价模型,构建宝鸡市生态安全评价指标体系,采用熵权法,得出DPSR各层以及整体综合评价的综合指数。结果表明:2012年-2021年宝鸡市生态环境综合指数大致呈“V”型分布,主体处于预警阶段,2016年处于中警阶段,生态环境最为恶劣,2021年达到较安全阶段,综合评价值达到最高。此外,宝鸡市生态环境主要的6个障碍因子分别是人均公园绿地面积、常住总人口、废水设施治理数、水厂生产能力、城镇居民年人均可支配收入、废水治理设施处理能力。为研究区生态环境保护、合理利用及发展方向提供科学依据。Based on data from 2012 to 2021,this paper selects the DPSR evaluation model to construct the ecological security evaluation index system of Baoji City,and uses the entropy weight method to obtain the comprehensive index of each layer of DPSR and the overall comprehensive evaluation.The results showed that the ecological environment comprehensive index of Baoji presented a V-shaped distribution from 2012 to 2021,with the main body in the early warning stage.In 2016,it was in the middle warning stage with the most severe ecological environment.In 2021,it reached the relatively safe stage with the highest comprehensive evaluation value.In addition,the six main obstacle factors of ecological environment in Baoji City are per capita green area of park,total resident population,number of wastewater treatment facilities,production capacity of water plant,annual per capita disposable income of urban residents,and treatment capacity of wastewater treatment facilities.It provides scientific basis for the protection,rational utilization and development direction of ecological environment in the study area.
