Landscape Ecological Planning Of Urban Green Space System

After the third scientific and technological revolution,the process of urbanization is accelerating with the coming of the new century.The urban land is increasing rapidly.Due to the destruction from human beings,the environment suffers from series of problems such as global warming,soil erosion,and resource reduction.With the rapid development of urbanization in China,how to rationally use the land resources and promote the development of urban and rural construction has become very challengeable.An example of destructive construction which cuts off the natural ecological environment can be seen in the expressway constructing.That and other similar behaviors have resulted in the vanishing of biodiversity and shrink of ecological space which is already very limited.Then green space loses its ecological function when used as construction lands.How to maintain the ecological landscape and enrich ecological spaces when keeping stable economic development has become an urgent problem in urbanization.In this paper,the landscape ecological planning of urban green space system is set as a major research direction.A set of corresponding landscape ecological planning models and methods is put forward on the basis of the study of ecological planning,landscape ecology,and urban green space system planning theory.At the same time,by means of a case study,the basic resources survey and current situation analysis of the green space system in Guangde County are carried out,and the strategy of landscape ecological planning,as well as construction of green space system in Guangde County,is put forward by using "macroscopy-midscopy-microscopy" planning method.Details are illustrated in five chapters:Chapter one is the literature review,which consists of the definition of the urban green space system,the concept of landscape ecological planning,and the summary of the domestic and foreign research status of green space system and landscape ecological planning.Chapter two is the introduction.The main content is the purpose and significance of the urban green space system landscape ecological planning research,as well as the representation of the technical route used in the research methods.Chapter three discusses the research of landscape ecological planning theory and methods of urban green space system planning,which is the key of this paper.First,the direction of landscape ecological planning of urban green space system and the summary of its structure and mode are given.Second,the planning procedure and planning content of the landscape ecological planning of urban green space system are discussed concretely,and a set of systematic planning methods for landscape ecological planning and design is put forward from the perspective of "macroscopy-midscopy-microscopy".The macro perspective has a view of an overall layout of landscape ecology planning and there are five ways of the layout.The main content of the middle perspective is planning green space by classification,including the establishment of related planning index system,park green space planning,ecological corridor planning,biodiversity planning and wetland planning.The micro perspective mainly considers tree species planning,establishing target zonal community system and reasonable plant selecting.Chapter four is a case study of landscape ecological planning in Guangde County green space system.This chapter base on the research of actual project to certify the relating planning theory and method in chapter three.Comprehensive investigation and analysis of the actual situation in Guangde County are shown,series relating problems of the green space system planning are summed up.Furthermore,feasibility strategy is put forward basing on the corresponding procedures and methods of the landscape ecological planning of the green space system in Guangde County.
