| there is no doubt,water resource is an important resource for human essential,is necessary for human survival,human development can not boiling water resources,is the material basis for the sustainable development of modern society,is the social stability and economic development for a long time is necessary for the development of natural resources,water resources is a part of ecosystem,but also to adjust effective control of ecological system.Since the industrial revolution,the process of city is more and more quickly,with the development of the industrial revolution,production rate increase,the city has become a global trend of development,city scale is continually expanding,affects the city industrialization also more and more profound and wide.The development of the city population increasing,city to the needs of the water resources quantity sharp growth,in order to obtain the available water resources more,a lot of groundwater mining city,the groundwater is not timely supply decreased year by year;a large number of water and waste of water resources so that the water balance of natural ecological maladjustment in large range;the number of water water destroys the benign cycle of natural water environment worsening ecological environment,these phenomenon and a series of problems of these phenomena is the production of human life inconvenient,hindering the construction in city life,the city water conservancy construction has become a problem that can not be ignored,more and more local the extensive and long-term attention all over the world.Without a doubt,the development prospects of city rainwater utilization foreseeable,suit one’s measures to local conditions for rainwater utilization plan,through scientific and technological innovation,continuously improve the utilization of rainwater resources city rate,the increasing use of city rainwater resources in production and daily life,will be the national and city to optimize the city structure to construct the necessary proposition of water-saving city to face the.To be sure,city rainwater resource industrialization can bring economic and social benefit and ecological benefit of city,city rainwater resource industrialization will promote contains rainwater collection and utilization,rainwater collection production and construction related processing facilities,as well as management related department of the enterprise and the other field--water effectively using a series of industrial chain,to become the new city development,ecological environment and promoting the economic growth point.The required,ease the city ecological deterioration in order to meet the city water,the collection and reuse of rainwater which is a new type of renewable water resources become an inevitable.This is the purpose of this study. |
