Applied Research On Utilization Of Rainwater Landscape In Residential Area

As we all known,Water is one of the most important source in life.During the process of urbanization,people tend to attach importance to social benefits and economic benefits and meanwhile ignore the ecological benefits.The contradiction between urban waterlogging and sever scarcity of water has increasingly intensified.The infrastructures and the way of disposing rain water are simplex.The way of disposing rain water mainly by draining away has caused largely loss of rain water resource.That’s way researching on the usage of rain water is very urgent.Taking the combination of rain water utilizing in residential region and landscape construction as point-cut in this research,we enrich the theory and method of utilizing rain water in our country by analyzing and using the experience of constructing rainwater landscape successfully at home and abroad.Aiming to the status of rain water utilization in our country,we put forward theoretical guidance and practical reference for how to strengthen the function of rain water collection and regulation and storage in residential Greenland,how to utilize rain water in a scientific and artistic way,and how to design the landscape in residential region.The followings are the main contents of this research.First,summarizing the measures and directions of utilizing rain water in residential region and indicating the status and deficiency of utilizing rain water in Greenland in our country through analyzing the progress and relative theories of utilizing rain water at home and abroad.Second,analyzing the successful cases of constructing rain water landscape in residential Greenland in order to sum up experience and point out deficiency.Third,putting forward thee water resource problem in residential Greenland and the method of utilizing rain water in residential Greenland sustainably and discussing the main measures and ways to utilize rain water and discussing the closed connection between constructing landscape and utilizing rain water.Fourthly,indicating the essence of constructing rain water landscape and its three basic principles,discussing the ways of rainwater storage and permeation and transportation and analyzing the practical application of all infrastructures to rain water landscape construction,making general layout of rain water landscape and building the holistic rain water utilizing system.Finally,Taking Yun Feng Lake placement community as an example,analyzing the current situation,formulating detailed measures to utilizing rain water and exploring the ways to combine rain water and landscape and calculating the suitable dimension of rain water garden,and then balancing the economic benefits and ecological benefits of rain water landscape so as to provide practical significance for constructing rain water landscape in our country.
