A solution to the problem of ecological environmental carrying capacity evaluation: a case study of Henan Province
摘要
Abstract
To evaluate eco-environmental carrying capacity,the core task is to estimate whether the intensity of human activity is within the threshold value of the eco-environmental carrying capacity.However,both the intensity of activity and the threshold value are difficult to measure correctly.In an attempt to solve the problem of evaluating eco-environmental carrying capacity,from the viewpoint of eco-environment system operating status,we present a new method of ecoenvironmental carrying capacity evaluation,called the " Eco-environment Index dynamic evaluation method," which is based on the ecological balance theory and the ecological stability principle.The processes adopted using this method are as follows.The first is providing an evaluation criterion of eco-environmental carrying status,that is,whether the ecoenvironment system is operating well.The second is calculating values of the eco-environment index (EI) in different years using an existing EI model.The third is judging the eco-environment system operating status based on the change trend of EI by regression analysis.Using these steps,eco-environmental carrying capacity can be evaluated.The evaluating process is demonstrated by using the case study of Henan Province,which yielded the following results.(1) Although ecoenvironmental carrying capacity evaluation is different from the EI,it can be performed by regression analysis of the EI.(2) This method,by following the strict definition of carrying capacity and avoiding the difficulty of estimating the intensity of activity and threshold value,provides a new way of thinking and a new approach to eco-environmental carrying capacity evaluation.Moreover,it is concise,easy to perform,and of clear significance.(3) Attention should be paid that the ecoenvironment quality cannot reflect the carrying status,for the region with a high eco-environment quality can be overloaded such as Xinyang,and the opposite case can be also exist such as Puyang and Anyang in Henan.关键词
