【摘要】：不断加快的城市化建设速度，使得城市的规模不断扩大，而整个西安市的水资源却跟不上其发展的速度，造成水资源短缺等问题较为严重。西安市地处我国陕西省黄河流域中部的关中盆地，其多年平均降雨量在614.6mm左右，具有丰富的雨水资源，对于雨水利用提供了相当便利的条件，这些丰富的雨水资源若能过有效利用，西安市日益紧张的水资源问题将可以得到有效缓解。本研究以维持小区建筑用地原有的水平为目标，查阅国内外城市住宅小区相关的雨水利用资料，以西安市某住宅小区为研究对象，研究雨水利用技术及结合利用模式，其主要研究结果如下： 1、根据西安市自然概况（地理、气候与土壤特征、降雨特点），对西安市进行雨水利用的可行性、必要性、可利用潜力进行分析。 2、本文通过对目标小区可收集的雨水量和用水量进行估算，同时进行雨水水量平衡分析；并结合该住宅小区不同类型下垫面的雨水水质变化情况，，对下凹式绿地，透水草坪砖，绿化屋面的蓄渗能力与减少的径流系数，进行理论研究论证并通过计算结果对比论证了其对于雨水利用系统的可行性。 3、通过对目标小区雨水年可利用量和小区年所需杂用水量的计算对比可知，其能够完全满足杂用需水量并且还有富余，对于其他需要用水的地方也能使用，并且可以有效减少小区周围由于降雨所产生的泄流压力以及提高其水资源的综合利用率。 4、结合下凹式绿地，透水铺装，绿化屋面的研究结果建立雨水收集回用系统流程和提出雨水综合利用模式,为西安城市住宅小区的雨水资源可持续利用提供了一定的理论基础与实践指导。 5、小区雨水利用具有良好的经济效益、社会效益及生态环境效益，对于城市小区广泛采用雨水利用系统具有相当的借鉴作用。
[Abstract]:The accelerating speed of urbanization makes the scale of the city expand, but the water resources of Xi'an can not keep up with the speed of its development, resulting in the shortage of water resources and other serious problems.Xi'an is located in the Guanzhong basin in the middle of the Yellow River basin in Shaanxi Province. Its annual average rainfall is about 614.6mm, and it has abundant Rain Water resources, which provides quite convenient conditions for the use of Rain Water.If these abundant Rain Water resources can be used too effectively, Xi'an 's increasingly tight water resources problem can be effectively alleviated.The purpose of this study is to maintain the original level of the residential land in the residential area, to consult the relevant Rain Water utilization data of the urban residential district at home and abroad, to take a residential district in Xi'an as the research object, to study the use technology and the combined utilization mode of Rain Water.The main findings are as follows:1. According to the natural situation of Xi'an city (geography, climate and soil characteristics, rainfall characteristics), the feasibility, necessity and potential of Rain Water utilization in Xi'an city are analyzed.2. By estimating the amount of rain water and water consumption that can be collected in the target district, and carrying on the balance analysis of Rain Water's water quantity, and combining with the change of water quality of Rain Water in different types of underlying surface of the residential district, the paper gives the concave green space and permeable lawn brick.The storage capacity of greening roof and the reduced runoff coefficient are studied theoretically and the feasibility of using the system for Rain Water is proved by comparison of calculation results.3. By comparing the annual usable quantity of Rain Water and the amount of miscellaneous water needed in the area, we can see that it can fully meet the requirement of miscellaneous water and has surplus, and can also be used in other places where water is needed.And it can effectively reduce the discharge pressure caused by rainfall and improve the comprehensive utilization of water resources.4. Combined with the research results of concave green space, permeable pavement and green roof, the flow chart of Rain Water collection and reuse system and the comprehensive utilization mode of Rain Water were established.It provides a theoretical basis and practical guidance for the sustainable utilization of Rain Water resources in Xi'an urban residential district.5. The utilization of Rain Water has good economic benefit, social benefit and ecological environmental benefit.
