Study On Rainwater Utilization Of City Park

The shortage of water resources has become a common concern of the whole society, howto study the sustainable utilization of water resources is an important content of all walks of life.Since the landscape industry is closely related with water, more attention should be paid to thesustainable use of water resources. How to use effective ways and measures for the city parkrainwater utilization is the purpose of this study.This thesis starts from a series of social problems caused by water, analyzes the importantsignificance of rainwater recycling. Through the analysis of present situation of city park water,this article emphasizes the importance of using rain water in city park, analyzes the Researchstatus and feasibility and necessity of rainwater utilization of city park.The main research innovation of this paper lies in its starting point---city park elements. Itanalyzes the ways and measures for city park rainwater utilization one by one and feasiblerainwater utilization facilities. it provides the basic idea for rainwater utilization in urban parkdesign:(1)Combined with paving rainwater utilization approaches and measures, analyzes from twoaspects, the permeable pavement and impermeable floor. Permeable paving rainwater utilizationis divided into rainwater infiltration and rainwater harvesting, impervious paving is divided intorainwater harvesting and rainwater drainage.(2)Combined with green rain ways and measures, starting from two aspects,the infiltrationof rainwater utilization of green space and green rainwater collection using. Penetration andutilization of green rain is divided into a sunken green space, rain gardens, low gradient green,slope of the green, greens, and a high of six green high coverage and dissect them one by one;Proposed the basic rainwater harvesting strategy to various types of green space.(3)Combined with water features, rainwater utilization approaches and measures, analyzesthe city park common artificial lake, constructed wetlands and other water features rainwaterutilization technical methods; rainwater utilization of the artificial lake is divided into theintroduction of the rain, ecological revetment and Lake water storage capacity of the body;artificial wetlands analyzes from two aspects, rainwater storage and rainwater purification;and italso introduces the fountain and other water features such as rainwater utilization strategies.(4)Combined ways and measures of using building rainwater, starting from the city parkconstruction characteristics, analyzes the roof rainwater harvesting, green roof applications aswell as roof rainwater drainage infiltration method.(5)Analysis of feasible rainwater utilization facilities in the city park, using methods such asartificial rainwater storage tanks, water purification facilities and infiltration facilities in city park.Through the above study, combined with dual-Hong Park, Chuzhou City, Anhui Province,South Qiao New practice cases, to explore the ways and measures for rainwater utilization in acity park planning, design and engineering feasibility, Theory implementation and actual project.This article attempts to explore the city park rainwater utilization ways and measures incombination with city park planning and design problems, and provides some valuable referencefor the garden industry practitioners in future work.
