【摘要】：城市化的快速发展对城市地区的自然水文状况造成严重影响,城市水资源紧缺、水体污染、洪涝灾害等问题综合并发。从20世纪60年代开始专门研究城市水的运动和变化的学科---城市水文学应运而生。近几十年来随着科技的进步,监测分析能力的提升以及国内外大量学者的参与,城市化地区水文效应的研究日趋深入和精细。城市化水文效应研究成为国内外学者研究的热点和前沿问题之一。目前,国内外城市化水文效应研究较为成熟。大量学者针对上海、北京、深圳、南京、济南等城市的城市化水文效应做有系统性深入的研究。武汉市作为长江流域的重要枢纽,荆楚大地的带动性城市近年来城市化水平快速提升,但是城市洪涝灾害屡屡发生,水资源紧缺问题渐渐呈现,水质污染普遍存在,因此研究武汉的城市化对于水文、水环境的影响,具有很大的必要性。本论文以武汉市相关数据资料为基础,结合其他学者的研究成果,从城市化水文效应的三个主要表现形式：城市化对于水文循环系统的影响、城市化对于水资源数量的影响,以及城市化对于水资源质量的影响为主要研究对象。鉴于水循环理论基础以及数据资料的限制,本文从降水和径流两个方面入手,研究城市化对于自然水循环的影响。因此本论文主要包括以下六个部分：第一部分介绍选题背景、研究意义、国内外研究现状以及论文的主要研究内容；第二部分阐述论文研究的相关理论基础；第三部分介绍武汉市的自然经济和城市化发展的基本概况；第四部分是论文的主体,分别从武汉市的城市化对于降水、径流、水资源数量以及水质等方面的影响研究武汉城市化的水文效应；第五部分结合武汉城市化水文效应的分析,提出武汉市的水文水环境改善策略；第六部分是论文的结论和展望,明确论文的不足和有望改进之处。
[Abstract]:The rapid development of urbanization has a serious impact on the natural hydrology in urban areas. The shortage of urban water resources, water pollution, flood disasters and other problems are concomitant. Urban hydrology, a discipline specialized in the movement and change of urban water, came into being in the 1960s. With the development of science and technology, the improvement of monitoring and analysis ability, and the participation of a large number of scholars at home and abroad, the study of hydrological effects in urbanization areas has become more and more in-depth and refined in recent decades. The research on the hydrological effect of urbanization has become one of the hotspots and frontier problems of scholars at home and abroad. At present, the research on the hydrological effects of urbanization at home and abroad is relatively mature. A large number of scholars have made systematic and in-depth studies on the hydrological effects of urbanization in Shanghai, Beijing, Shenzhen, Nanjing, Jinan and other cities. Wuhan, as an important hub of the Yangtze River valley, the belt city of Jingchu land has been rapidly increasing its urbanization level in recent years. However, the urban flood disasters occur frequently, the water resources are in short supply and the water quality pollution is widespread. Therefore, it is necessary to study the influence of urbanization on hydrology and water environment. Based on the relevant data of Wuhan city and the research results of other scholars, this paper analyzes the three main forms of the hydrological effect of urbanization: the influence of urbanization on hydrological circulation system, the influence of urbanization on the quantity of water resources. And the impact of urbanization on the quality of water resources as the main research object. In view of the theoretical basis of water cycle and the limitation of data, this paper studies the effect of urbanization on natural water cycle from two aspects of precipitation and runoff. Therefore, this paper mainly includes the following six parts: the first part introduces the background of the topic, the significance of the research, the domestic and foreign research status and the main research content, the second part describes the theoretical basis of the paper research; The third part introduces the basic situation of Wuhan's natural economy and urbanization development. The fourth part is the main body of the paper, which studies the hydrological effects of Wuhan urbanization on precipitation, runoff, quantity of water resources and water quality from the impact of urbanization in Wuhan. In the fifth part, based on the analysis of the hydrological effect of urbanization in Wuhan, the author puts forward the strategies of improving the hydrological and water environment in Wuhan. The sixth part is the conclusion and prospect of the paper, which makes clear the deficiency of the paper and the hope of improving it.
