Study And Optimization Of The Landscape Structure Of Green Corridors In Nanning High-tech Industrial Development Zone

As the link connecting the city Green Heart,the urban green Corridor has the important function of realizing the material and energy exchange between the city and the region,improving the urban ecological environment and providing the recreation space for the urban residents,therefore,many cities realize the effective improvement of the urban environmental quality and the overall improvement of the urban landscape level through the construction of urban green corridor activities.This study discusses the related concepts,basic structure and functions of urban green Corridor,expounds the research methods of the present situation of urban green corridor,and applies these theories and methods to the study of the landscape structure of green corridor in Nanning Hi-tech zone,which mainly includes the landscape composition of green corridor,network structure,The relationship with the urban green heart and the current situation of the internal structure of the study.It is pointed out that the following problems exist in the green corridor of Nanning high-tech zone: The tranquil area is not fully connected with the other two areas through the green corridor,forming an independent green corridor system,which will have the island effect for a long time,and the poor connection between the green corridor and the green heart in each area hinders the flow;The green corridor has more discontinuity,low connection rate and lack of loop,the green corridor width is narrow,the construction rate is low,it is difficult to construct green travel green space,and it is not conducive to the formation of internal habitat,and the road greening allocation in each area is not reasonable,which restricts the full play of the ecological service function of green corridor.According to the problems existing in the green corridor of Nanning Hi-tech zone,combined with the actual situation of the road,river and Urban green area of the high-tech zone,the optimization goal of the green corridor in Nanning Hi-tech Zone is scientifically set,and the overall layout optimization of the "two-axis,four-loop,six-axis and seven-longitudinal lines" Based on the conditions of the road in the high-tech zone,the optimum width of all kinds of green corridors is put forward,and the scheme of optimizing the internal structure of green corridor by setting up green car belt and reasonable collocation of greening plant species is put forward.It is considered that optimizing and constructing green corridor in Nanning Hi-tech Zone provides a theoretical basis for improving the ecological environment,improving landscape quality and shaping urban green recreation space in Nanning high-tech area,and strengthens people's cognition of Urban Green Corridor and provides a new construction idea for urban green sustainable development.
