| 摘 要： | 为给2022年冬奥会提供良好的生态环境,以崇礼区为研究对象,运用综合评价模型对该区进行生态环境评价。构建了以自然环境、经济水平、社会发展3个层次17个指标的评价体系,以熵值确权法确定各指标权重,采用加权法计算生态环境综合指数。结果显示:2015-2018年期间崇礼区各年度生态环境综合指数分别为0.7099、0.8150、0.9512和0.9736,环境质量有明显提升,2017-2018年均在优的状态。

| Abstract: | In order to provide a good ecological environment for the winter Olympics and test the results of supply-side reform,taking Chongli District as the research object,comprehensive evaluation model was used to evaluate the ecological environment of this area.A three levels of 17 indexes evaluation system that include the natural environment,economic level and social development was established.The weight of each index was determined by entropy value method.The comprehensive index of ecological environment was calculated by weighted method.Result shows that:From 2015 to 2018,the ecological environment comprehensive index of Chongli District is 0.7099,0.8150,0.9512&0.9736.The environmental quality is significantly improved,and the average annual average is in an excellent state from 2017 to 2018. |
