Landscape Planning And Design Of Urban Waterfront Green Gallery Based On Green Infrastructure Theory

At present,a variety of urban diseases have emerged in the process of rapid urban development,especially water environment problems such as urban waterlogging,water pollution and sudden decline of biological diversity.In order to cope with flood and waterlogging disasters,people blindly cut the river straight and built hard revetment,which gradually lost the natural ecological function of the river and damaged the natural environment,thus affecting the social and economic development.Green infrastructure as an important means of green infrastructure,marina aqua green corridor as a kind of linear green space,the study was based on green infrastructure of urban water-front aqua green corridor landscape planning and design,play to its ecological service function,social and economic aspects of the potential to solve serious urban ecological problems has the very good help.The waterfront green corridor planned by means of green infrastructure can give full play to the ability of various water bodies and green Spaces to control stormwater runoff,alleviate flood disasters,restore the ecological environment and increase biological diversity,etc.,with positive and significant ecological benefits.By means of multidisciplinary literature review,combination of theory and practice,field investigation,case analysis and induction and summary,this paper,on the one hand,elaborates the domestic and foreign theories on green infrastructure and waterfront green corridor,and summarizes the construction mode of waterfront landscape in small and medium-sized cities.On the other hand,the actual cases of waterfront greenway landscape planning and design based on green infrastructure at home and abroad are analyzed and summarized.Taking the landscape planning and design of he river waterfront greenway in ji ’an county,jiangxi province as an example,the main existing problems of the site include frequent flood and waterlogging disasters,serious water pollution,destruction of animal and plant habitats,lack of landscape facilities and incomplete site functions.The planning and design of he river waterfront green corridor are based on the research of green infrastructure,and the corresponding optimization strategies are proposed :(1)ecological restoration;(2)stormwater regulation and storage;(3)overall connection;(4)diverse functions.From medium city site and micro spatial scales,through the green infrastructure will shore city aqua green corridor of the natural ecology and landscape features,the combination of flood control and construction of rainwater harvesting,ecology,recreation and other multi-function as one of the complex marina aqua green corridor,connect natural areas and other open space,forming a network of interconnected green space.This paper explores the strategies and approaches of urban waterfront greenway landscape planning and design based on green infrastructure,in order to provide some reference and ideas for the construction of waterfront greenway in other small and mediumsized cities in the future.
