分别采用模糊数学的隶属度方法和系统动力学方法,考虑了水生态承载力评价因子和评价过程的不确定性,对区域水生态承载力的评价进行量化研究.根据常州市武进区的水生态承载力的评价结果可知,研究区的水生态承载力属于不可承载状态,区内的人口、经济规模已超过承载力的临界值,亟需改善水质条件和生态环境状况,使经济社会得以持续、良性发展.通过对比2种评价方法可知,隶属度评价水生态承载力的方法简便、易行,系统动力学则具有系统、综合的优点,考虑的因素较全面,在水生态承载力量化研究中可根据不同的条件和具体情况选用不同的方法.
Taking fuzzy mathematics membership degree method and system dynamics method respectively, the evaluation index of aquatic ecological carrying capacity and the uncertainty of evaluation process are taken into account, and the assessment of regional aquatic ecological carrying capacity is quantitatively studied.According to the water ecological status of Wujin District, Changzhou The evaluation results of the bearing capacity show that the water ecological carrying capacity of the study area belongs to the unbearable state. The population and economic scale of the area have exceeded the critical value of the carrying capacity. Therefore, it is imperative to improve the water quality conditions and the ecological environment so that the economy and society can be sustained. By contrasting the two evaluation methods, the method of membership degree to evaluate aquatic ecological carrying capacity is simple and easy, and system dynamics has the advantages of systematic and comprehensive consideration, and the factors considered are more comprehensive. In the quantitative study of aquatic ecological carrying capacity According to different conditions and specific circumstances choose different methods.
