Study On The Response And Coordination Relationship Between Urbanization And Water Ecological Environment In Benxi

In recent years,the rapid development of urbanization in China has caused the consumption of resources and the continuous emission of pollutants discharged in the surrounding environment,and a series of ecological environment problems generated.China attaches great importance to the construction of ecological environment,under the guidance of revitalizing the old industrial base in Northeast China as well as the other principles and policies,it is a practical subject to study the relationship about response and coordination between urbanization and water ecological environment and realize the coordinated development between them in Benxi.On the basis of summarizing the research of both domestic and foreign on the relationship between urbanization and water ecological environment,the indexes of urbanization and water ecological environment were selected and the evaluation index system was constructed,and a qualitative analysis of the response relationship and the coordinated development between 2000~2014 was made,the main conclusions are as follows:1.Select 10 indexes from four aspects of population,space,economy and society,to evaluate the level of urbanization in Benxi,The results showed that the level of urbanization in Benxi has entered a stage of rapid development.2.Establish ecological evaluation index system based on P-S-R model,select the 10 indicators from the three aspects about pressure,state and response of water ecological environment to evaluate,the results showed that the ecological stress,state and response score of Benxi city showed their own characteristics.The comprehensive index of water ecology,water ecological pressure index and water ecological state index showed "U" curve,it showed that the water ecological condition of Benxi had a tendency of going bad before it gets better.But there is a general upward trend about water ecological response index,which reflects the efforts of Benxi in environmental protection.3.Through the establishment of the response relationship between urbanization and water ecological environment in Benxi,it is found that: According to the development characteristics,the response relationship can be divided into two stages,inclouding 2000~2008 and 2009~2014,and the response relationship between urbanization and water ecological environment and its components showed different response functions,which shows that Curves have different expression in the actual example of different forms4.Through the establishment of the coordinated development model of urbanization and water ecological environment in Benxi,it is found that: The Benxi city has experienced a process from a lagging behind urbanization to a lagging behind water ecological environment.And the development of the coordination level has experienced a process from the barely coordination into good coordination.5.Based on the study of the relationship between urbanization and water ecological environment in Benxi City,countermeasures for the development of Benxi have been put as follows.Benxi should continue to strengthen the speed and quality of Urbanization,and the attention should be payed to the protection of the water ecological environment,to achieve the development of urbanization and water ecological protection at the same time.
