The Strategic Study About Greenway Planning Of Waternet City In Southern Jiangsu Province Based On The Ecological Conception

In the process of urbanization in our country, water network construction and development of the city in the south of Jiangsu is relatively quickly. Due to water ecological landscape with high sensitivity, rapid urbanization brought about by the ecological environment problem is increasingly outstanding, such as drainage ecological function, regional water features disappear and the obvious contradiction between protection and development, etc. The greenway as with linear, connectivity, multi-functional open space and urban corridor, it is an effective way to solve the problem of city status. Therefore, through the analysis of characteristics of the natural ecology of water city in the south of Jiangsu and strategy, current problems and puts forward the greenway planning for construction of ecological city and provide theoretical guidance to build urban ecological pattern, is the focus of this article and meaning.First of all, this paper analyzed the ecological structure characteristics of water city in the south of Jiangsu, summarize and analyze the present situation and causes of urban problems to put forward the importance of the greenway planning from the perspective of ecology, to provide targeted the greenway planning research foundation. Secondly, based on the analysis on the present situation of city, combining the theory of landscape ecology, giving priority to the green way of ecological function and connectivity, aiming at constructing urban ecological security pattern, proposed the greenway planning strategies: one is the general layout of a macro level through green layout influence factors and sensitivity analysis of ecological resources, on the basis of the greenway node and route selection evaluation standard, determine the node and route choice, combined with the surrounding land use status under the background of different layout strategy and layout structure; Second, medium level of planning and design, in view of the special water environment from the integration of scattered around the node, attaches great importance to the ecological planning and perfect the slow study on planning and design service system in three aspects. Finally, the greenway planning in Suzhou city as an example, case analysis, through practice of greenway planning strategy of water city in the south of Jiangsu, feedback and optimization.
