| With the improvement of living standards,the demand of our residents that people need for leisure agriculture and rural tourism products or services is increasing.Compared with Western and Japan,the research and development of leisure agriculture in China had started late.In spite of rapid developing,and obtaining a lot of achievement in economic,social and ecological,the research and development of leisure agriculture seldom integrate low impact development technology into it.Besides,there have in view of the great differences in natural conditions of different regions,such as topography,climate and environment.So,it has certain academic value and practical significance to integrate low impact development into leisure agriculture for specific regions.In view of this,this paper toke the LID leisure agricultural park in Sichuan and Chongqing as the research object.Firstly,the concept,characteristics and functions of LID leisure agricultural park were defined by sorting out and analyzing the domestic and foreign literature and the LID leisure agricultural park in Sichuan and Chongqing province were investigated on the spot.Secondly,the basic strategy of planning and design of LID leisure agricultural park in this area were put forward based on the analysis and summary of the investigation data and the characteristics of ecological environment in Sichuan and Chongqing province.Finally,the strategy is applied in the actual case of Chongqing Beibei leisure agricultural park planning and design.The main conclusions were as follows.(1)Relevant references of theoretical research at home and abroad were read,with analyzing LID,leisure agriculture,LID leisure agricultural park and other related concepts.There have elaborated the characteristics and functions of LID leisure agricultural park,as a special type of leisure agriculture.LID concept and technical measures were effective ways for leisure agricultural park to achieve good ecological benefits,and develop and plan in leisure agricultural park the core of this paper.(2)To investigate the current situation of low impact concept and measures in the development and construction of leisure agricultural park,three projects such as Mingyue village of Pujiang county,Duoli organic ecological farm of Pidu districtb of Chengdu city,and Zhuli village of Daoming town of Chongzhou city have been selected as target cases.This paper analyzed the expression of low impact development concept,application types of typical local materials and main low impact facilities in the construction process of Mingyue village.We analyzed the expression of low impact development concept and main low impact facilities in the construction process of Duoli organic ecological farm.We analyzed the expression of low impact development concept,application types of typical local materials and main low impact facilities in the construction process of Zhuli village express the current situation in the development and construction of the park.In all,the paper summarized the shortcomings of LID concept and technology in leisure agricultural park in Sichuan and Chongqing.(3)Based on the above theoretical research,field case study,the geographical features and local characteristics of Sichuan and Chongqing,the paper put forward the planning strategy and six system design methods of LID leisure agricultural park.It includes the concept,principle,construction points and development process of the park planning and design.The six system design include terrain system,water system,transportation system,building system,agricultural production system and landscape plant system.The terrain system includes flat vertical design,slope vertical design,and infiltration basin design.The water system includes the protection and utilization of the original water system,the construction of water system,the design of ecological revetment and water bank derivative zone,and the collection and utilization of rainwater resources.The transportation system includes local ecological road design,road combined with green LID special design and ecological compensation of road design.The building system includes the protection and renewal design of the original building,the three-dimensional rainwater management measures of the building,and the layout of the new building to avoid damage.Agricultural production system includes object selection and design,water system design,fertilizer control system design,pest monitoring and early warning system design.The landscape plant system includes plant design of service facilities,plant design of road,plant design of water system and forest network design of farmland.(4)Taking the planning and design of leisure agricultural park of Chongqing province as the practice,they were applied in the actual case.The project planning strategy includes planning principles,concepts,structural functions and industrial layout planning,low impact planning of the park,environmental capacity estimation.The LID design was respectively carried out for six systems in the park,such as terrain system,water system,transportation system,building system,agricultural production system,and landscape plant system.We combined theory with practice,with designing a special leisure agricultural ecological park,which integrates the functions of high-quality product production,natural ecological restoration,sightseeing experience,cultural display,and popular science education.It provides a possible reference for the development,construction,planning and design of LID leisure agricultural park in the future. |
