Abstract


As urban development and urban environmental issues have become increasingly prominent building an eco-city has become an inevitable trend in the future of urban construction and development. Urban ecological corridor to build a sound system of urban ecological green space has a vital role in it as a necessary urban natural landscape \urban ecological health maintenance force. Chongqing, the youngest municipality in China, with the rapid economic development, ecological environment and health of the city's increasingly important. Therefore, the study unique topographical features, combined with the Chongqing mountain city landscape spatial structure of the existing system of ecological corridor in Chongqing City, to discuss the problems and deficiencies in the main city of Chongqing in the ecological corridor construction to construction characteristics of Chongqing urban ecological corridor system provide a theoretical reference and practical guidance on the health of the city's ecological environment, sustainable development is important. With the AutoCAD2006 drawing and calculating tools and GIS information system software analysis of the ecological corridor of the main city of Chongqing city landscape spatial structure on the level of the two scales, the problems and deficiencies of the main city of Chongqing urban ecological corridor: ecological Gallery Road construction total lack of green ribbon ecological corridor along the east and west sides of the natural ridge distributed unevenly distributed and the number of deficiencies: road type ecological corridor and river ecological corridor construction to be improved, in particular, should strengthen quickly River ecological corridor outside the building of roads and two rivers; ecological corridor width is smaller, a smaller proportion of the core corridor, the ecological corridor network connectivity is not enough; inner city green patches between green plaque ecological sources Inter did not form an effective communication. Characteristics of natural and geographical conditions and location of the main city of Chongqing, the overall layout of the planning and construction of the main city of Chongqing urban ecological corridor on the macroscopic scale reference and recommendations. Then, in the main city within select representative areas range as a meso-scale study to explore various ecological corridor within the function, shape, width and internal structure of a planning proposal. And to map out the distribution of improved ecological corridor network topology map, computing landscape Index, compared with the existing ecological corridor and ecological corridor after the transformation can play a greater ecological benefits. Studies have shown that the series of ecological corridor within the scope of the study layout, width, shape and internal structure: First, on a macro scale, the overall layout of the urban ecological corridor should meet on the number and location of the effectiveness and continuity towards should be parallel to the dominant wind direction with the city to meet the requirements to reduce the heat island effect. Secondly, the ecological network in each grade scale should be complete and continuous; Third, specific planning and construction of a ecological corridor in microscopic scale, the construction of objects of natural geographical environment, the status of the regional background and its surrounding land use patterns, the ecological corridor planning objectives and the main function of determining a decisive role, thereby affecting the planning and construction of specific shape and structure of the ecological corridor; Finally, this mountain city of Chongqing, Chengdu, Wuhan and other plains urban geographical conditions and there are big differences between the natural environment, in the planning and construction can not copy the plains of the greening of the city construction mode, should be adapted to local conditions, and take full advantage the Chongqing mountain urban terrain varied advantages to carry out the construction of urban ecological corridor.
