大庆市生态环境质量定量计算与分析

Quantitative Calculation and Analysis Eco-environmental Quality in Daqing City

为了确定大庆市生态环境质量状况,根据《生态环境状况评价技术规范(试行)》(HJ/T192—2006)中的方法对大庆市生态环境质量指数进行定量计算,选用基于层析分析法(AHP)的综合评价方法对大庆市的生态承载力进行计算。生态环境指数计算结果表明:"十一五"期间,大庆市各评价区域的生态环境状况指数均无明显变化,年度变化幅度在-0.12～0.18之间,生态环境状况较为稳定。生态承载力计算结果表明:大庆市生态系统处于较稳定状态,水资源是影响评价区域生态弹性度的主要因素;大庆市资源承载力处于较高水平,其中矿产资源承载力较高,水资源承载力较低;大气环境承载力处于较高水平,水环境承载力较低;大庆市目前的承载压力度(CCPS)小于1,具有一定的发展空间。

In order to understanding the ecological environmental quality of Daqing City, the eco-environmental quality indices of Daqing were calculated according to “Technical Criterion for Eco-environmental Status Evaluation”, the ecological carrying capacity of Daqing were calculated by the comprehensive evaluation method based on the Analytic Hierarchy Process （AHP）. The results of eco-environmental indices calculated showed that, during the “llth five year” period, eco-environmental indices of different evaluation regions in Daqing showed no significant change, annual change amplitude was during -0.12 to 0.18, ecological environment was relatively stable. The results of ecological carrying capacity calculation showed that, the ecological system of Daqing city was steady, water resource is one of the most important factors that affecting the ecological resilience of evaluation region; the resources carrying capacity of Daqing were in higher position, in which the mineral resources carrying capacity was higher, water resources carrying capacity was lower; atmospheric environmental carrying capacity was higher, water environmental carrying capacity was lower. The current carrying capacity pressure （CCPS） of Daqing was less than 1, the region has some room for development.
