Study On Landscape Planning And Design Method Based On Lid On Site Scale

Low impact development is from the source,to maintain or restore the site's natural hydrological base,small-scale,decentralized technical measures to achieve a comprehensive management and control of rain protection of a site development model.But now the development of the city land type is changed,the use of the site of impervious surface expansion,coupled with the municipal facilities "drainage" drainage system is not perfect,resulting in many problems caused by rain resources,environment,ecology,society,etc..In this background the city ecological corridor as the main object of study,through literature review,case analysis,field research method,comprehensive induction,planning and design method,with low impact development to provide some advice to the Taizhou area rainwater management.This study is based on the theory of low impact development and its related theories,and summarizes the research progress at home and abroad.(1)The study has an important influence on low impact development theory and the related concepts of system design goals and principles of building and design process,and play a major role in the natural hydrological cycle in the rain is one of the site of the sustainable development of the main problem,so in the planning and design should focus on the problem of rain start.(2)The research progress at home and abroad through the literature research and analysis,we can see that foreign rainwater control facilities are complete,perfect design of rainwater infiltration and rainwater collection system,also promulgated the relevant laws and regulations,building standards,formed a relatively mature theory and technology system.Study on the application of LID at home and abroad is still in the initial stage,mainly by absorbing the foreign advanced idea and technology,relevant laws and regulations need to be further improved,coupled with the ingrained traditional concept of development at home,which makes LID facing lots of obstacles in the domestic promotion.(3)Through the analysis of domestic and foreign cases,clear application of low impact development have been implemented in the project,the results achieved,and can learn from the methods,have a certain reference for the actual project later.(4)Through the example of Taizhou sea corridor planning respectively expounds the method of low impact development in the planning and design of concrete,including the conditions analysis,the establishment of ecological safety base,land use planning,water system planning,green roof design,road design,vertical design,pavement design,parking lot design etc..The plant is an important part of the water cycle,and the selection and distribution of plants in different LID measures are summarized.The varieties of plants suitable for each facility are enumerated.
