The Research On The Construction Strategies Of Urban Green Ecological Network

With the accelerated pace of urbanization, continuous expansion of urban construction land leads to continual loss of species habitat and the growing of habitat fragmentation. Facing a deteriorating urban environment, how to resolve conflicts between the urban development and ecological environment, and how to explore the city’s sustainable development have become an important subject of Chinese urban development. Green ecological network, as a protection and restoration of natural resources in a holistic approach, is important for sustainable development of the city space and solving the urban ecological environment. It links all kinds of ecological and cultural resources and urban functional space to form a coherent urban green space network, playing an important role in creating city livable environment. Green ecological network is rich in connotation, from the classification of scales, including land ecological security pattern, regional ecological network, microscopic green infrastructure in urban built-up area and so on, it also has multiple functions, including hydrological protection, biodiversity conservation, cultural heritage conservation, recreation resources integration, etc. In this paper, the urban green ecological network is focused on the macro network system of urban scale.while promoting the biological protection, it also provides the main structure of urban green space network (Heritage Protection Network and Recreation Network).This paper analyzes many relevant green ecological network cases at home and abroad, and summarizes the comparative analysis of practical case and research case, biological leading case and composite case, domestic practice case and foreign practice case. Based on this starting point, with the research on influence which the evolution of landscape ecological planning theory and method of constructing strategies produces on green ecological network, this paper summarizes the construction strategies of city green ecological network, mainly divided into two categories:project strategies and implementation management strategies. In addition, project strategies can be divided into two categories:strategies of green ecological network based on ecological protection and strategies of green ecological network based on humanistic recreation protection. Finally this paper summarizes the urban green ecological network construction strategy system, to provide the reference for the domestic city construction ecological network, and takes the Beijing city as an example to explain. Inspired by the era of big data, this paper discusses the future of the green ecological network construction strategies in the end.
