【摘要】：在构建河北省生态环境安全评价指标体系的基础上,根据生态环境安全评价原则,运用层次分析法,结合定性、定量分析对河北省2005—2014年生态环境安全进行评价,分析生态环境安全变化的影响因素。结果表明,2005—2014年河北省生态环境安全指数为3.40~3.68,平均值为3.55,随年份增长呈小幅波动、总体下降趋势;河北省生态环境安全等级为4级,总体处于较安全状态,但存在退化现象,生态环境安全形势严峻;河北省生态环境安全变化是由自然因素和人为因素共同作用,相互影响。
[Abstract]:On the basis of constructing the evaluation index system of ecological environment security in Hebei Province, according to the principles of ecological environment security evaluation, the analytic hierarchy process (AHP) is used to combine qualitative analysis. Quantitative analysis was carried out to evaluate the ecological environment security in Hebei Province from 2005 to 2014, and the influencing factors of the ecological environment security change were analyzed. From 2005 to 2014, the ecological environment safety index of Hebei Province was 3.40 ~ 3.68, with an average value of 3.55, which fluctuated slightly with the increase of the year, and decreased gradually. The level of ecological environment security in Hebei Province is 4 levels, which is generally in a relatively safe state, but there is a phenomenon of degradation, and the ecological environment security situation is grim. The change of ecological environment security in Hebei Province is influenced by both natural and human factors.
