区域水生态承载力优化-以湖州市为例

he concept of water ecological carrying capacity was defined and the water ecological carrying capacity index system which contains state index and control index was proposed. Also, the multi-objective optimization model combining with scenarios analysis method was established in this paper. The optimal scenario was selected by using genetic projection pursuit model. Huzhou city was taken as an example. Five scenarios (status quo, develop as planning, low tense pollution control, normal tense pollution control, high tense pollution control) were set and optimized by multi-objective optimization model. The high pollution control scenario was recommended by using the genetic projection pursuit model. According to the recommended scenario, the population of 2.636 million and GDP of 190.63 billion can be carried by its water ecological system; The ecological water demand was guaranteed, and the maximum use rate of water environmental capacity was 98% , and the utilization rate of water resources is 18.1%.
