【摘要】 城市的快速发展产生了一系列水问题。一方面,由于人口和经济活动的集中,城市建筑面积不断扩大,不透水地面增加,城市的暴雨径流产生的洪涝灾害不可忽视。另一方面,城市淡水资源匮乏,迫切需要寻找新的供水水源。雨水资源作为轻度污染的水源,水中污染较少,经过简单处理就可用于生活用水和工业用水。因而增加城市雨水资源的利用量,避免其灾害,并且提高城市雨水资源的利用率将是节水型城市建设的有效措施。本论文主要研究了城市雨水利用与城市水环境的改善。在调查国内外城市雨水利用发展状况及实例的基础上,分析了城市化进程中,城市化对水资源、水环境、水循环造成的影响,以及城市化、水环境与城市雨水利用的关系,深入研究城市雨水利用的必要性和可行性;对城市雨水利用进行分类,探讨城市雨水利用的途径;对城市雨水利用的理论基础进行研究,建立城市雨水利用基本方式和步骤,并进行分类讨论;探讨城市雨水利用景观及其对城市水环境的改善,并通过对雨水渗透理论和设施的分析,结合计算机模拟计算(运用hydrus软件进行数值模拟)等方法,分析雨水入渗对地下水的影响,提出雨水渗透对城市水环境改善的作用。在具体应用研究上以邯郸市为背景,选取邯郸市美意苑为具体研究区域,进行了雨水资源利用的系统分析。初步研究成果如下:①运用hydrus软件进行数值模拟,分析降雨入渗对地下水的影响。②对邯郸市的典型次降雨进行分析,得到邯郸市降雨量和雨水利用的关系,作为雨水利用量计算基础数据。③根据美意苑居住区的规划情况,分别对该流域使用透水性地面前后进行汇流量计算。④分析计算流域内各种地面收集的雨水量,并且计算美意苑居住区的绿地和草坪用水。最后对美意苑居住区流域内收集的雨水量与居住区内绿化用水进行分析验证,得到绿化用水的水量仅占收集的雨水量47.1%和58.1%。更多还原

【Abstract】 The fast development of cities caused a series of water problems. On the one hand, with the centralization of the people and the economic activities, extension of the urban buildings and increase of the area of impervious stratum, the flood caused by urban storm flow cannot be neglected. On the other hand, new water-supply source is urgently demanded for the scarcity of urban fresh water. As a kind of slightly polluted water source, rainwater has less contaminations and it can be used as domestic water and industrial water by simply treatment. So the exploitation of the urban rainwater and making best use of the urban rainwater will be the effective measures of the water-saving city.The primary purpose of this paper is to research the utilization of urban rainwater and the improvement of urban water environmental system. Based on the investigation of the present research of the utilization of urban rainwater, it analyze the influence of urbanization on water source, water environmental system and water circulation, the relationship of the urbanization, water environmental system and the utilization of urban rainwater, and research the necessity and feasibility of the utilization of urban rainwater; The utilization ways are classified and the utilization modes are discussed; On the ground of the theoretical basis of the utilization of urban rainwater, the basic mode and procedure of the utilization of urban rainwater are established and discussed; After the discussion of the landscape and its contribution to the improvement of urban water envirorunental system and the analysis of the theory and facilities of rainfall penetration, combine imitate a calculation of computer(Make use of the hydrus software carries on number emulation ) method and so on, the analysis rainfall penetration to the groundwater influence,the effect of rainfall penetration on the improvement of urban water environmental system is presented.On the specific application study, the paper makes a systematic analysis of the utilization of rainwater on the community of MeiYiYuan in HanDan. The findings of the paper are as follows:①M ake use of the hydrus software carries on number emulation,the analysis rainfall penetration to the groundwater influence.②The analysis of rainfall gives the relationships of distribution of rainfall and the utilization of rainwater as basic data for the utilization of rainwater.③According to plan situation of the community of MeiYiYuan,the amount of afflux of the basin used water-permeable ground around are calculated.④Rainfall that can be collected in each situated area and the water amount used on lawn are calculated. The amounts of two kinds of water are compared and then we can see that water amounts used on lawn are 47.1% and 58.1% of rainwater that can be collected in two drainage areas respectively。更多还原
