Landscape Structure Of Research In Urban Ecological Corridor In Fuzhou

As a part of the urban landscape of green space system, the research of urban ecological corridor has become an important field of studying landscape ecology now. Well-constructed urban ecological corridor will not only to maintain the stability of the urban ecosystem, but also to provide the public good green recreational spaces. This paper expounds the gradual deterioration of urban environmental problems in urgent need of renovation based on the research of ecological corridor. The basic principles of ecological corridor concept, function and classification provide theoretical basis. This paper analyses the ecological corridor landscape architecture in the center of Fuzhou by combining macro-mesoscale methods.This paper study the landscape structural of the central city of Fuzhou by using of geographic information software in a macro perspective. The results of calculating the length, area and completion rate show the problems and the insufficiency of the urban ecological corridor in Fuzhou. Investigate on the construction of urban ecological corridor by mesoscale, found that he width of the road and river ecological corridor is not enough to form internal habitat, green patch fragmentation is obvious, the connectivity to road corridor is poor, vegetation allocation is irrational, including how to allocate herb bushes and trees and poor three-dimensional spatial structure. According to Fuzhou City Planning Bureau relevant documents and site visits, combined with the characteristics of the wind climate, make a rational planning of Fuzhou urban ecological corridor network systems, expounds the specific optimization of construction scheme:"a barrier, three stripe, two rings, seven gallery, multi-point multi-channel"(Building the barrier as the north of mountains, two riparian along river as the central, Erhuan road and Sanhuan road as the framework, using all kinds of roads and rivers to connect ecological patch which all around the urban, then the urban ecological corridor network system would be formed). And propose specific optimization program based on regional land use conditions and functional requirements. Finally, introduce natural wind outside the city to the city by the rational layout of ecological corridor, achieve a good cycle of urban microclimate combine eco-corridor road, river ecological corridor and plants configuration. Exert the ecological function (such as reducing the Reduce the urban heat island effect, dispersing pollutants, urban air purification) of urban ecological corridor fully.
