Study On Planning Of Ecological Farm Based On Stormwater Management

Aiming at the problems of drought and flood disasters, water pollution, waste of water resources, agricultural irrigation water shortage and agricultural production, landscape, service functions that ecological farms undertakes, etc. The paper takes stormwater management practice of vegetable technological and ecological farm at Dangwu Town of Gui’an New Area in Guizhou Province as the research object. The specific research contents, methods and conclusions are as follows:(1) The present research progress and development of rainwater management and ecological sightseeing agriculture at home and abroad were analyzed. Besides, the research content(methods and measures of stormwater management, specific implementation strategy of stormwater management in ecological farm), research significance and technical methods were defined.(2) Outlined the source type and distributed rainwater management theory such as best management practices(BMPs), low impact development(LID), split-flow theory, artful rainwater design(ARD) and so on. Described the relevant theoretical basis from the technical system classification, management process and some other aspects. Furthermore, researched specific technical measures through the practical application of rainwater management.(3) Based on the ecological benefit, economic benefit and social benefit provided by stormwater management, summarized the existing stormwater utilization technology of high-efficiency agriculture from aspects of rainwater collection, storage and use. And divided the ecological farm site into hard and soft underlying surface types, respectively explored the specific stormwater management measures applicable to different types of underlying surface, such as green roofs, permeable pavement, rain garden, rainwater storage and reuse system and other technical measures.(4) Taking the planning and design of vegetable technological and ecological farm at Dangwu Town of Gui’an New Area in Guizhou Province as object, through the analysis of the natural conditions and ground runoff, worked out rainwater management strategies and runoff design for ecological farm site conditions. Explored the concrete implementation strategy and engineering technology of stormwater management applied in ecological farms, and provided specific indicators and expected effect of rainwater design in the scheme.(5) Summarized the importance of this topic, the methods of water management, the specific implementation strategy of the planning and the discussion of problems that stormwater management encountered in practice at the end of the paper. In addition, described the expected results of stormwater management from the positive value, hydrological function, ecological protection and other aspects.
