| Industrial structure,as an important reflection of the major economic activities of a city,indicates the civic economic development and overall economic strength.Varied industries differ in their impinge upon environment.Furthermore,under the some economic aggregate,different industrial structure will cause dissimilar environmental consequence.Thus,industrial structure has a strong influence on the environmental quality of a city.By applying the method of grey relevance analysis,the thesis studies the development of three industrial structures of Chang-Zhu-Tan City-Cluster Group during 2000-2006 and the relation between the development of various trades in every industry and the pollutants that affect environment. It also analyzes the influence of industrial structure on environment with the help of quantitative analysis and qualitative analysis. Firstly,using the grey relevance analysis to research the three kind of industrial structures of Chang-Zhu-Tan City-Cluster Group and get the conclusion that,presently,secondary industry mainly contributes to the GDP of Chang-Zhu-Tan City-Cluster Group. Tertiary industry grows rapidly and its relation degree GDP closely follows secondary industry. The lines which enjoys a higher relation degree in secondary industry is industry,which primarily effects the development of secondary industry. Although tertiary industry also grows fast, its lines like wholesale, catering industry and tourism ect, are equipped with inadvanced technology and develop comparatively slowly.Secondly,through the quantitative and qualitative analysis of the influence of three industrial structures on environment, it is distinct that secondary industry has the strongest influence on environment. Moreover, its energy consumption, material consumption and pollutants are much more than the other industries due to its own characteristics. Primary industry takes up a small proportion in the whole industry, therefore, it will not cause severe consequence. In comparison whit primary industry and secondary industry, tertiary industry effects a city's ecological environment least.At last,the analysis of the three industries shows that industrial pollution is the chief reason of the environmental deterioration of Chang-Zhu-Tan City-Cluster Group,then it evaluates the impacts of the industrial development in Chang-Zhu-Tan City-Cluster Group on environment in terms of gross industrial output value and energy consumption. Aiming at those problems, we put forward the suggestions as follows: adjust the energy consumption structure, promoting clean coal technology, encourage the development of environment-friendly industries, rational planning industrial layout, strengthen institution building and set up a regional eco-coordination mechanisms. |
