The Planning Program Of Rainwater Collecting And Reusing In The Changsha Yanghu Wetland Park

The current problem of scarcity of water resources is increasingly serious, caused floods in the desert problem has occurred frequently, only will rain quickly discharged water infrastructure has been unable to meet this need, will be treated as rainwater collection, osmosis, use of multi-function rainwater management research has become the focus of the society as a whole, and is closely related to water the garden industry, but also because of the research in the recycling of water as the key. How to effective let city parks and stormwater management measures complement each other, make it play a series of ecological function is the purpose of the study in this paper.In changsha, yanghu wetland park as the research object of this topic, on-the-spot investigation, literature review and data graphic method is used for yanghu wetland park, has carried on the analysis and summary of the current situation of changsha yanghu wetland park at present physical rainwater management measures are put forward the design strategy, so as to curb flood hazard, slow stormwater runoff, reduce water pollution, and puts forward the measures such as rainwater utilization method, expectations for other city parks or other areas with valuable reference.(1) The present situation and shortage problem of water facilities at home and abroad are summarized, combined with the city park, will play the advantages of the stormwater management, and other areas for future city parks of the significance of rainwater utilization.(2) Detailed introduces the physical rainwater management measures, can be divided into the following four link, the sewage collection, infiltration recharge, storage storage, purification treatment measures.Many measures for control of the application of runoff, filtered rainwater pollution, flood prevention, prevent waterlogging, and the use of rainwater utilization at a significant effect.(3) And aiming at yanghu wetland park of rainfall, topography, vegetation, drainage condition are analyzed and summarized, based on rainwater collection using made a holistic planning, put forward measures for dealing with rainwater management system, not only weakened the rainwater runoff, but also to the rain of the pollutants removal efficiency, and the years of 1818641m3 of rainfall collection and can save water more than 500 ten thousand yuan.System is too big and stormwater management measures, application prospect in the field of city parks and other also quite comfortable. But there are also many shortcomings, but also need our mutual exchanges and cooperation in more discipline and engineers, the runoff pollution control, and the removal effect of be more WanShanHua, selection for base on the evaluation system, still need to do deeper research in more extensive field practice to lay the foundation for the future.
