The Study On Relationship Between Sustainable Development And Coordinated Development

The sustainable development is the inevitable trend of our human society development ,it gained more and more attention in recent years .City as a com-ecosystem, it can't without the coordinated of itself to achieve sustainable development. Although sustainable development and coordinated development are closely related, we can not equate sustainable development with coordinated development,otherwise it will lead the city develop deviating from the correct path ,so it is very importment to find out the relationship between theirThe paper bulit the sustainable development evaluation model on the base of sustainable development and complex carrying capacity theories. It evaluated the sustainable development state of Wuhan city and did a comparative analysis of the sustainable development with coordinated development of Wuhan city.The main content and conclusions of the thesis are as follows:(1) A model of urban sustainable development evaluation has been set up , and also indexes system .Taking Wuhan's urban ecosystem from 1988 to 2005 as an example, the result indicates:the development of wuhan is become sustainable development from un- sustainable development.(2) Based on the urban com-ecosystem theory, The society, economics, resource-environment coordinated evaluation model was established with benefit-balance thoery,and the status of coordinated development from 1988 to 2005 in wuhan was evaluated with principle component analysis. It was showed that the urban ecosystem comprehensive development level improved steadily and coordinated development were facing tremendous pressure.The coordinated development indexes are depression, and the trend of development is not stable, also, the situation is not good. From 1988 to 1999,wuhan is in awful disorders or excessive disorders, and from 2000 the situation is taking a good ture, the condition in 2005 tured to barely coordination.(3) Using correlation analysis to find out the relationship between sustainable development and coordinated development of Wuhan city.It shows that there was a positive correlation between coordinated development and relative carrying capacity,but the correlation between coordinated development and the change of carrying capacity is not obvious ,This indicats:to improve the coordinated development helps the arrival of sustainable development ,but we should not only do this to realize sustainable development.(4) The importment influential factors of sustainable development and coordinated development of Wuhan city were selected by grey incidence analysis.Based on this,the tendency of the sustainable development and coordinated development were simulated with BP neural network.It found that the development of wuhan will be sustainable and coordinated,but it could not reach the state of good coordinated developmen in 2020. In the end, based on the result of estimating and forecasting model, the recommendations on Wuhan were given.
