Preface

The process of water resource development and utilization is nothing more than the process of open source, throttling, pollution reduction, and efficient allocation. In this process, science and technology play a vital role. Urbanization refers to a historical process in which the rural population is constantly shifting to towns, and the secondary and tertiary industries are converging to towns, thereby increasing the number of towns and expanding the size of towns. Its main manifestations are that with the development of social productivity in a country or region, the advancement of science and technology, and the adjustment of the industrial structure, the migration of rural residents to urban areas and the transfer of rural labor employment to urban secondary and tertiary industries. The process of urbanization is also a reflection of the social changes experienced by various countries in the process of industrialization and modernization.                         

Urbanization is not only an increase in the population and number of cities, but also the further socialization of cities and the intensification of resources. It is a complex process of spatial changes and social and economic development.

Urban water supply project is an important infrastructure to protect urban residents ’living and ecological environment. The scientific operation of urban water supply system is directly related to the quality of life of residents and the effective use of water resources. In the design and construction of urban water supply projects, the overall scientific planning and rational design are necessary.

Therefore, the content of this book provides a comprehensive description of water resources utilization and urban water supply projects, hoping to help the work of relevant staff.

前言

水资源开发利用的过程不外乎开源、节流、减污降排和高效配置的过程，在这个过程中，科学技术起着至关重要的作用。城镇化是指农村人口不断向城镇转移，第二、三产业不断向城镇聚集，从而使城镇数量增加，城镇规模扩大的一种历史过程。其主要表现为随着一个国家或地区社会生产力的发展、科学技术的进步以及产业结构的调整，其农村人口居住地点向城镇的迁移和农村劳动力从事职业向城镇二、三产业的转移。城镇化的过程也是各个国家在实现工业化、现代化过程中所经历社会变迁的一种反映。城镇化不仅是城市人口和城市数量的增加，也包括城市的进一步社会化和资源的集约化，是一个复杂的空间形态变化和社会、经济发展过程。

城镇供水工程是保障城市居民生活和生态环境绿化用水的重要基础设施，城镇供水工程系统的科学运行直接关系居民的生活质量和水资源的有效利用，在城市供水工程设计施工中，需要做到整体规划科学和设计合理。

因此，本书内容对水资源利用及城镇供水工程进行全面的阐述，希望能够有助于相关工作人员的工作开展。
