Research On Environmental And Economic Coordinated Development Of Chuanyu Urban

After the reform and opening up, Chinese national economy has achieved remarkable achievement, but the problem of environmental and resource shortage has followed. At the same time, along with the rapid development of industrialization and urbanization, with developed traffic network, and gradually perfect the system of urbanization gradually close correlation of economic development, some cities began to be in harmony of regional scale of economy and environment, the connection between the cities development degree has been strengthened.Along with the deepening of the regional economic division of labor and specialization and the rapid development of regional economy, economic factors on the spatial agglomeration phenomenon more and more obvious, gather more and more extensive。Due to the agglomeration effect and formation of the cluster economy has replaced the original independent agents, become the core of regional economic growth and development.Among them, the urban agglomerations as a typical representative of clustering, its formation and development for the coordinated development of regional economy and environment plays a decisive influence.ChuanYu urban agglomerations as a new type of urban agglomeration, the research is very little, most of the focus on the study of each urban agglomeration spatial structure, economic development, but few studies from the perspective of the coordinated development of economy and environment, as a key city in the western development, with the continuous development of economy, research on the coordinated development of economy and environment has more important practical significance.So the each urban agglomeration coordinated development of economy and environment, to promote the sustainable development of each region and even the entire western region has important significance.In order to better guarantee the social, economic and environmental coordination under the current development of the new normal, stable and sustainable development, this paper selected in each urban agglomeration, chengdu, chongqing, zigong, mianyang, nanchong) five typical cities as the research object, in comprehensively and systematically collected city’s natural environment, social economic development, environmental quality and pollution emission data and other information, on the basis of urban agglomeration of economic and environmental sustainable development research, paper and related work has carried out the following work:1)In the development of regional society, economy and environment, the development of urban agglomeration is the core and the concrete means of awareness.Throughout the world history experience of the development of society, economy, environment analysis, deep understanding to the urban agglomeration is the pattern of economic development in the core of the most dynamic and potential region, urban agglomeration in our country productivity layout plays a strategic point and the role of growth pole, bearing the national and regional convergence of various factors of production flow and diffusion functions, is the important direction of future city in China.2) The understanding of environment and economy coordinated development theory and analysisThrough the "coordination and development", "harmonious development", "coordination degree and coordination development degree" of dialectical analysis, as well as to the current sustainable development four basic approaches and kuznets curve theory and practice based on the summary and analysis of both at home and abroad, this thesis clearly recognize that sustainable development theory emphasizes the coordinated development of environment and economy, the pursuit of the harmony of man and nature. The central idea: be healthy based on ecological economic development sustainable ability, social justice and people actively involved in their own development decision-making basis; Goal: is to meet the diverse needs of modern people, both to protect the environment, no offspring caused harm to ecological environment; Development indicators: not just use GDP as the only index to measure development, but with the social, economic, environmental, and other indicators to measure, the pursuit of sustainable development.3)The estibatishment of urban agglomeration coordinated development of environment and economy comprehensive evaluation method, related to the construction of index system and evaluation modelThrough statistical yearbook of each city and other environmental and economic data, first of all, the data is standardized, entropy value method is used to determine the index weight, and then according to the formula of environmental and economic comprehensive strength, as well as the environment and economy coordinated development degree model, obtained each of five urban agglomeration in 10 years environment comprehensive development level, the comprehensive economic strength level, environmental and economic coordination degree and coordination development degree.4) For each urban agglomeration coordinated development of environment and economy comprehensive evaluationEach urban agglomeration as the northwest region economy more developed urban agglomeration, the coordinated development of environment and economy for the sustainable development of the northwest has the guiding significance.Environmental and economic comprehensive strength reflects each urban agglomeration level of independent development of environment and economy, the calculation of its coordination degree and coordination development degree further reflects the coordinated development of urban agglomerations. By analyzing the data, each urban agglomeration coordinated development of environment and economy.Each urban environment comprehensive strength on the whole presents the twists and turns upward trend, while each urban agglomeration economy has been at the stage of rapid growth; Each urban environmental and economic coordination degree by the start of disorder to the general coordination and even quality coordination, explain each urban agglomeration in recent years in pursuit of economy at the same time, pay more attention to the development of the environment, but from the perspective on the coordinated development of environment and economy, even in basic benign coordination, but also can see that the environment is still lag, this also shows that each urban agglomeration in the pursuit of rapid economic development, environmental quality still needs to be improved.5) The Kuznets curve in chongqing empirical and inspectionIn Chongqing as an example, through to the chongqing in 1990-2011(in per capita GDP) economic growth and environmental pollution(water, gas and solid) relationship of empirical analysis shows that the industrial wastewater and there is obvious EKC relationship between per capita GDP, the EKC turning point has been reached. Industrial waste gas emissions with the increase of per capita GDP, there is a clear downward trend, leveling off in 2005, and with the increase of per capita GDP, industrial solid waste production amount and soot volume increased, rising.6)The analysis of the typical regional atmospheric environmental changesWith the rapid development of economy, urbanization process accelerated, the improvement of people’s living standard, the regional environmental quality has become a public attention; Especially the atmospheric pollution of the environment become one of the most concern in the world.Of chongqing city in recent 10 years the analysis of the change of atmospheric environment quality, overall, chongqing’s air quality has improved markedly in ten years, from 2005 years ago, three levels of pollution, after 2005, atmospheric environment quality conforms to the national secondary standard. Specifications, after 2005, atmospheric pollution in chongqing has the obvious effect, chongqing atmospheric environmental quality improved.7)The Suggestions of sustainable development in the study areaOn the comprehensive analysis and evaluation of each urban environment and coordinated economic development level and the controlling factors, on the basis of summary of each urban agglomeration environment and economy coordinated development problems, corresponding effective Suggestions and countermeasures are put forward. Such as optimizing the industrial structure, the transformation of the mode of economic growth and promote the sustainable development of environment and economy; Establish perfect environment and economy coordinated development evaluation mechanism, strengthen environmental protection mechanism; Development of circular economy, promote clean production, making a group of high technology content, low environmental pollution of advantage industry; Strengthen the recycling resources, classify the garbage and waste recycling and comprehensive utilization and guarantee the implementation of circular economy system.
