Symbiotic Study Of Road Network And Water System In Hilly Region Of Small And Medium-sized City

With the accelerating of urbanization,the influence of road network to water system is continue expanding,urban water system degradation is serious,the contradiction between urban development and environmental protection is increasingly deepened.On the one hand,people search for ecological services which the water system can provide.The water system as the ecological corridors can provide human with continuous ecological service function,and with modern technology is widely used in water system protection,a variety of functions of water system is developed and used.On the other hand,it is hoped that from the increasingly expanding road network to obtain more economic benefits,this brought serious threat to the ecological system of water,damage to the ecological environment of river system,hilly landscape characteristic features and destruction of the species diversity,etc.In view of this,the natural factors of urban road network to small and medium-sized city in the hilly region and the ecological impact of road network to water system were fully discussed in this paper.On the basis of introducing the theory of road ecology,we are analysis the road network and water system integration symbiosis,and then propose the symbiosis methods between them.Finally we are also appraising the symbiosis network which we built.Full text is divided into three parts:The first part mainly put forward problem.We have been discussed the change of the drainage pattern under the urbanization and the natural factors of road network to water system,puts forward the research question.On the basis of stating the research significance and the related research both at home and abroad,we put forward the research content and frame.The second part is about analysis problem.From the concept of hilly area,small and medium-sized cities,road network,water system,we analysis the influence factors of urban road network in the hilly region and the ecological impact of road network to water system.The third part is about solving the problems.according to the analysis of the first part and second part,the introduction of road ecology theory,from the macro,meso and micro three aspects discusses the hilly region of small and medium-sized city road network structure,road corridor,key point and important area with water system symbiosis of fusion,and proposed the corresponding countermeasures symbiosis.Finally the south of new city water system and vegetation protection plan in Jiangxi Wanzai has carried on the case study as an example,and for the construction of the greenway network is evaluated.
