Dalian Urban Ecosystems And Their Coordinated Development Research

This article systematically expounds the theoretical analytic model of the urban ecosystem and its coordinated development research by using the theoretical basis of urban ecology environmental material economics, urban economics, urban geography and urban planning. On the basis of these theories, the article analyses the urban ecosystem of DaLian City in its structure character and also the interactive relation between the ecosystem and the development of the society with the method of integrating theory and practice and quantitative and qualitative . When it comes to systematically analyze the urban social economy and the coordinated development of ecological environment, carry out the research of regional sustained development, instruct and coordinate the construction of the urban ecosystem in DaLian, the article can be a valuable reference material and it is also important in a practical sense. The article contains four chapters. The main ideas of the four chapters are listed below:The first chapter theoretically analyses the urban ecosystem and its coordinated development research . On the basis of determining the intension of urban ecosystem the chapter emphatically discusses the character, structure, function of urban ecosystem and the basic theory and method of urban ecosystem and economic coordinated development research. The urban ecosystem is a complex of society, economy and nature that consists of urban population and many natural factors that include urban bio-community of plant, animal and microorganism, urban geology and landform, urban hydrology and water resource, soil resource. The urban ecosystem have not only the ecological process and function that is homologous with natural ecosystem but also characteristic and other opening, complex and unstable character. With the developmentof the citifying and modern city, the construction and coordinative development of urban ecosystem has become the important research field of ecology and many other subject, such as environmental economics, urban planning, urban economics.The second chapter sets out with the essential factor of nature, society, and economics. Taking ecosystem and resources, regional economic development, urban distribution and population as the main point, the chapter systematically analyses the structure and character of DaLian urban ecosystem. The DaLian area have the latest type and structure of landform that consist of mountain, hills, mesa, marine corrosion land. In the aspect of area distribution, the east is warm and moist continental monsoon climate, but the west is the warm and submoist continental monsoon climate. In DaLian, the most river originate from the zone of mounds in median area and diverge in the direction of east or west. According to the utilization of water resource, the industry and life is the major way to the south of JinZhou, but to the north of JinZhou is the agriculture. The diversity of soil type in DaLian determines the character of ecosystem and the shape of the area distribution. DaLian City is the important costal industry city, harbor city and modern tour city in China.The third chapter mainly analyzes the whole arrangement of eco-community of DaLian city and the construction of the ecological demonstrate region of JinZhou, including the industry structure adjustment of city region, the synthetical regulation of environment, and the construction of special ecological region such as forest park, protected region, interest of place and so on in the north and suburb. This greatly accelerates the development economy and acquire great social economy benefit. JinZhou promotes greatly agricultural ecology construction by ecology views and system methods such as the theory of the living things symbiosis, the cycle and regeneration of material and energy, the cooperation of living and environment and soon in according to the featureof natural resource and environment in order to realize the organic combination of energy ecology and society.The fourth chapter mainly makes a compr...
