The Study Of Space-time Relations About Ecological Risks And Economic Development In Dongying City

Nowadays, people pay more and more attention to the environment Problems, and the relationship between economy development and chemical pollution has become hot point to the scholars both at home and abroad. Economic development is always the pursuit of national or regional goals. Economic development will not only promote social progress, resources and energy will lead to failure, resulting in ecological risks. Dongying City is located in Yellow River Delta area efficient ecological economy, whose ecological environment has always been of concern.Firstly, the ecological risks of Dongying City, the status and level of economic development have been studied for the relationship between the two studies providing an important prerequisite. The time and space relations of Ecological risks and economic development in Dongying City mainly are discussed from two aspects. First, it analyzes the economic development of Dongying City, on the impact of time and space to the ecological risks. In l995, American economist Simon·Kuznets putted forward the famous Kuznets income reverse U curve. The Environmental Kuznets Curve (EKC) is usually used in examining the relationship between economy and the environment. Using statistical data of 1989, 1996, 2000 and 2005, the paper selects for the EKC model, analyzes the EKC features and the economic impact on ecological risks. Second, it analyzes the ecological risks of Dongying City, on the impact of time and space to the economic development. This paper estimates by an econometric model to verify that results are consistent with the qualitative judgments. Finally, the proposals are put forward in order to coordinate the relationship, for example, accelerating industrial restructuring, reasonable investment and consumption, and effectively controlling of population size, etc.This paper has mainly found the following conclusions: Firstly, the ecological risks are assessed through the AHP in 1989, 1996, 2000 and 2005. By evaluation we can know the ecological risks'changes in time and space. With time, Dongying ecological risks are gradually increased. In space, the risk intensity is generally reduced from coastal areas to inland, showing ladder-like distribution.Secondly, Model proves the existence of Kuznets inverted U-curve, but still in the curve of the left. So far in 2005, the increase in per capita GDP will stimulate the increase of ecological risks, exacerbating environmental pollution and destruction. In addition to per capita GDP, the industrial structure, consumption, investment and population density are also the important factors to affect Kuznets inverted U-curve. There are the strong links among them by using regression analysis.Thirdly, Economic model calculates and verifies the ecological risks of Dongying City impediment to economic development. In time, the environment Continues to deteriorate and ecological risks gradually increase in Dongying City. In turn, they limit the sustainable economic development. Therefore, we have to minimize ecological risks to reduce obstacles in the economic development of Dongying City.
