Abstract:

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 "11th 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.
