The Research Of Megalopolis Overall Development Framework In "DaHunTai" Basin Valley Harnessing

With the arrival of the period of all-round construction of ecological civilization, the pursuit of "Efficiency first" planning of urban and rural economic and social development thinking has do not conform to the construction of ecological civilization, in the future of urban and rural planning work, with "Ecological environment" as the first value orientation planning ideas more obvious superiority, to guide the sustainable development of urban and rural planning. Urban development in the future will no longer rely on road for endless expansion and spread to outer space, but tend to rely on rivers, and other natural ecological environment, ecological factors in development.In this paper. through comparison and research at home and abroad related river management and river basin management cases, summed up the river management purpose is not pure water quality improvement and the recovery of ecological environment, but by building a good water environment and ecological environment to promote urban economic recovery, the reappearance of the stability of the urban social life and the urban vitality. Paper, "big muddy too" basin developing problems of carding, analysis the main reason, combining river basin management connotation, summarized "DaHunTai" basin valley harnessing three contents, namely, rivers, ecological restoration and urban space remodeling.Thesis by describing the basin management related content, to redefine the river and the ecological environment in the basin is an important position in economic and social development in valley town, river basin management to improve urban area as a whole development. And derived with the basin ecological environment as a whole town, the economic and social development idea, innovative "Basin Megalopolis" is put forward.River basin as a whole the miles and areas of the city development in river basin region coordination, the social harmony, resource saving and environmental friendly as the basic principle, the basin water environment and ecological environment, urban economic development, urban spatial structure, infrastructure and landscape culture construction as a whole, to achieve the symbiotic development of watershed ecology and watershed town. Building is to promote continuous area of city drainage basins, the regional economic, urban and rural development as a whole of the middle and lower reaches, the sustainable development of river basin, and the optimization of spatial form of economic and social resources.Paper with "DaHunTai" river basin as the object of empirical study, combined with the "DaHunTai" basin valley harnessing, put forward the ecological environment and urban township as a whole basin city area development strategy. In view of the basin and water conservation ecological environment construction in river control, ecological environment restoration, ecological wetland construction and ecological landscape corridor construction strategy; To urban development of economy, trade and industry transformation, the integration of infrastructure construction, protection of historical cultural heritage and interlocking region, valley city new town construction, and the seven cities in the basin development strategy research, and the formation of river basin ecological environment and urban coordinated development of "DaHunTai" Basin Megalopolis, to realize the sustainable development in river basin.
