Research On The Ecological Corridor Planning Under The Ecological Security Pattern

The ecological problems behind the accelerating urban process are gradually prominent,and the establishment of ecological security pattern has become an important direction to establish an ecological garden city.In the construction of urban ecological security pattern,corridor plays an important role in landscape link and transition,and is an important factor in landscape patch fragmentation.This paper will discuss the planning and design of ecological corridor from the perspective of ecological security pattern,and study the role of ecological corridor according to the ecological security pattern of water environment,biological protection and security pattern,geological disaster and historical and humanistic protection and security pattern in the ecological security pattern.The literature review mainly elaborates the theoretical knowledge of ecological corridor and ecological security pattern.The introduction part proposes the purpose and significance of the research,and explains the method and process of the research.In the body part,the basic function of ecological corridor is firstly analyzed,and the ecological function of river ecological corridor,road ecological corridor and forest ecological corridor under the ecological security pattern is analyzed and studied.Then,according to the least resistance model,the potential ecological corridor is identified in GIS software and the comprehensive security pattern of the research area of liantang river in nanchang county is constructed,which provides the basis for the next planning and design.Finally,according to the current situation of liantang river and the comprehensive security pattern of the research area,the overall ecological design was carried out.Starting from the dredging design of the whole river bank,the design of ecological revetment,human node partition and plant theme partition was designed.The development of ecological corridor has been accompanied by the development of urban construction.The integration of ecological corridor into the landscape infrastructure will provide important ideas and methods for the sustainable development of the city,and make the ecological corridor the ecological corridor and the green framework of the city.
