Research On The University Campus Landscape Construction Based On Rainwater Resources Utilization

The water pollution and the shortage of water resources has become a worldwide concernproblem,with the the acceleration of urbanization process, the problem of water resource hasseriously restricted the sustainable development of the city. As an important part of nature watercirculation system, rainwater is a natural water resources with mild pollution. The universitycampus is an important part in the city,The campus crowd and a large quantity of building need agreat amount of water, with the combination of utilization of rainwater and campus landscape isan effective way to solve campus landscape water circulation.This thesis consults a lot of domestic and international relevant rainwater utilization literature,understanding the theory,the related concept of rainwater utilization and the relationship betweenthem.Combined with the domestic and foreign research, proposed the problems of campusrainwater utilization in China,and analyzes some outstanding case of campus rainwaterutilization,we know that the study combined with campus landscape rainwater utilization has ademonstration and exploration nature.Based on the geographical location,climate,city meteorological conditions and theevaluation of urban rainwater utilization potential in Zhengzhou, analyzing the necessity andfeasibility of rainwater utilization in this city, which will provide background support forrainwater utilization in Zhengzhou campus.Colleges and universities is an important part of the city, advanced concepts and managementwill play an exemplary role in rainwater utilization,Taking Zhengzhou college campus as anobject, select12universities in different range of Zhengzhou City, through the campus buildingroofing, road material and form, green elevation, waterscape patterns and rainwater pipe networkfacilities statistical and survey, it is obvious to see that the awareness of using rainwater in collegeconstruction is not strong, There has no complete system of rainwater utilization on campus andcausing a huge loss of rainwater resources.According to the basic principles and the influent factors of creating landscape which basedon rainwater utilization on campus in Zhengzhou city,the author puts forward3kinds of rainwatercollection mode, by comparing the proposed scheme put forward the most suitable one forZhengzhou campus.From four main aspects to discuss the way of rainwater collection to be usedin landscape construction,they are roofing, road, green space and water features, and finally setHenan Agricultural University as an example, based on the existing problems and potentiality ofrainwater resources situation, designed the landscape rain water integrated process,and finallyestimate the economic benefits, ecological benefits and social benefits in university campusrainwater utilization.Finally, Through estimate the rainwater resources in Zhengzhou City, quantified the rainwater resources, through the study of campus rainwater utilization in landscape design,aimedto provide a reference for other regional rainwater utilization.
