As the infrastructure of our country’s economy and society, water conservancy construction benefits the people and becomes an indispensable support to promote the sustainable development of economy. In the 21st century, modern water conservancy faces the severe challenges of water resources shortage and ecological environment deterioration while building a comprehensive flood control and disaster reduction system. Rational utilization of water resources and construction of water conservancy will still be an important strategic measure to ensure the development goal of China in the new century. Water conservancy has a long history and a wide range. In the vast number of water conservancy projects, it is not easy to select famous water conservancy projects. Due to the difference of engineering properties and various categories, it is difficult to unify the standards of water conservancy projects. The basic principle is that among all kinds of water conservancy projects that have been completed and are to be completed, water conservancy projects with the characteristics of “high, large, heavy and special” are selected, with outstanding scale, benefit, style and certain popularity. Among them, there are many dams of more than 100 meters, hydropower stations of more than one million kilowatts, irrigation areas of one million mu, large-scale water conservancy projects, important flood control projects, and projects with distinctive characteristics and special impact, etc. From a comprehensive point of view, “famous” also includes projects that should learn lessons due to major problems or accidents.
With the development of water resources in China, more and more attention has been paid to the environmental problems in the construction of water conservancy projects. We should pay attention to the protection of ecological environment in every link of planning, design, construction, operation and management of the project. At the same time, measures such as science and technology, economy and law should be taken to establish the management system of the construction environmental protection. We should make clear the respective responsibilities of the owner, the supervisor and the construction unit, formulate the plan of the environmental protection during the construction period of the project, minimize the damage to the original ecological environment caused by the construction, and coordinate the construction of water conservancy project with the sound cycle of resources and environment and the sustainable development of society and economy.

水利建设作为我国经济社会的基础设施，造福于人民，成为促使经济可持续发展不可或缺的支撑。继往开来， 21 世纪现代水利面临的是在全面建设防洪减灾体系的同时，重点解决水资源紧缺和生态环境恶化的严峻挑战，合理利用水资源与兴修水利仍将是保证我国新世纪发展目标的一项重大战略措施。水利历史悠久，范畴广泛。在浩如烟海的水利工程中，选取著名水利工程并非易事。由于工程属性差异、门类繁多，给水利工程的统一标准带来了困难。基本原则是，在已建成和待建成的各类水利工程中，选择了具备“高、大、重、特”的特点，其规模、效益、风格突出，并享有一定的知名度的水利工程。其中不乏百米级以上的大坝，百万千瓦以上的水电站，百万亩灌区，大型水利枢纽，重要的防洪工程，有鲜明特色及有特殊影响的工程等。从全面观点出发，“著名”之中也纳入了因存在重大问题或是失事出险而应吸取经验教训的工程。
随着我国水资源的大力开发，水利工程施工过程中的环境问题受到人们越来越多的重视，我们应在工程的规划、设计、施工、运行及管理的各个环节中都要注意保护生态环境，同时，还应采取科技、经济、法律等措施，建立施工环境保护管理体系，明确业主、监理和施工单位的各自职责，制订工程施工期环境保护计划，尽量减轻施工对原有生态环境的破坏， 使水利工程建设与资源环境的良性循环和社会，经济的可持续发展相协调。

With the rapid development of China’s economy, more and more water conservancy projects are constructed, but there are some problems in the quality of current water conservancy projects, which cause the hidden danger of project safety. As an indispensable part of urban construction, water conservancy project construction quality determines the development of municipal construction, and the level of construction management plays a decisive role in the whole project. At present, although the construction management level of water conservancy projects in China has been greatly improved, but there are still some deficiencies in the specific construction process, we must give a full understanding, take effective measures to improve the construction quality of water conservancy projects.
This book will mainly discuss four aspects of water resource safety, water conservancy project construction, water conservancy project management technology, flood prevention and disaster reduction safety technology.

随着我国经济的飞速发展，水利工程施工越来越多，但是当前水利工程的质量存在一定的问题，造成了工程的安全隐患。水利工程作为城市建设不可缺少的重要部分，水利工程施工质量的优劣决定了市政建设的发展，施工管理水平的高低对整个工程起着决定的作用。当前，虽然我国水利工程施工管理水平较之前有了很大的提高，但是在具体施工过程中还存在着一些不足，必须给予充分的认识，采取行之有效的改进手段，提高水利工程的施工质量。
本书将主要通过对水资源安全、水利工程施工、水利工程管理技术、防汛减灾安全技术等四个方面进行一定的论述。

The main purpose of water conservancy project is to reduce the flood disaster. Its construction relationship is an important matter of national economy and people’s livelihood. The construction of water conservancy projects must be in accordance with certain management standards, while the existing engineering construction technology and management technology standards in China obviously cannot meet the needs of economic development and the people. Water conservancy project construction and management as a public welfare project, is mainly controlled by the state. As early as in the 1990s, after the reform of management system, the system of separation of administration and enterprise has been clarified. Many construction units have been transformed into independent legal persons, thus forming the construction management mode of project legal person responsibility system. However, the separation of government and enterprise responsibility system has gradually separated the construction and management of water conservancy projects from the government, especially the local water conservancy departments. The development of construction and management of water conservancy projects has more freedom, and also breeds many management deviations, which eventually leads to the failure of water conservancy projects to achieve the expected results. As a project of benefiting the people and benefiting the people, there are still many things to be improved in the construction and management of water conservancy projects. In the construction of water conservancy projects, we should put the construction of management technology standard system in the first place. Only by establishing a scientific and reasonable standard system can we make water conservancy projects into real projects for people’s livelihood. Under the guidance of economy, we should gradually change the current situation that the current system is lack of many items, the starting point is low, and the technology and technology are not matched, so as to make the construction and management of water conservancy projects develop healthily. In this book, the introduction, water conservancy project construction, drought and flood control project, water conservancy project management system mode, water conservancy project quality supervision and management will be briefly described.

水利工程主要是为了减少水患灾害的，它的施工建设关系是国计民生的大事。水利工程的建设施工必须按照一定的管理标准，而我国现有的工程施工技术和管理技术标准显然不能满足经济发展和人民的需求。水利工程建设与管理作为一项公益性的惠民项目，主要由国家进行把控。早在 20 世纪 90 年代，经过管理体制的改革，已经明确了实行政企分离的体制，不少建设单位改制变为独立法人，从而形成了项目法人责任制的建设管理模式。但是，这样的政企分离责任制度导致水利工程建设与管理逐渐同政府分离开来，特别是地方水利部门，水利工程建设和管理的发展具有更多自由性，也滋生出很多管理偏差，这样导致水利工程建设项目最终没有达到预期效果，作为惠民利民项目，水利工程建设与管理仍旧有许多待改进之处。在水利工程建设中我们要把管理技术标准体系的建设放在首位，只有制定了科学合理的标准体系，我们才能把水利工程做成真正的民生工程。我们要以经济为指导，逐渐改变现行体系缺项多、起点较低、技术工艺不配套等现状，使水利工程建设及管理得到健康的发展。
本书将通过绪论、水利工程建设、抗旱防汛工程、水利工程管理体制模式、水利工程项目质量监督管理等方面进行简要的阐述。

With the continuous development of social economy and the continuous expansion of the water conservancy project market, there are higher requirements for the quality and level of water conservancy project construction. The normal operation and production of water conservancy projects can not only ensure the safety of people’s lives and property, but also bring economic benefits to the country and the people. This requires scientific and reasonable management methods to improve the construction management level of water conservancy projects, thereby enhancing the quality of water conservancy projects and ensuring the smooth progress of water conservancy projects.
At present, China’s water conservancy project construction has developed to a high level, but there are still a lot of problems. This requires further strengthening the level of water conservancy project construction management to support China’s water conservancy project development in a better direction. This book introduces water conservancy project construction management from ten chapters, with detailed content and comprehensive knowledge. Hope to promote the development and progress of water conservancy in China.

随着社会经济的不断发展，水利工程市场的不断扩大，对水利工程建设的质量和水平有了更高的要求。水利工程建设的正常运行和生产，不但能够保障人民的生命财产安全， 还能够为国家和人民带来经济效益。 这就需要有科学合理的管理方法，提高水利工程建设管理的水平，从而加强水利工程建设的质量水平，保障水利工程建设顺利进行。
目前我国的水利工程建设发展到了一种高水平状态，但是仍然存在着不小的问题，这就要求进一步加强水利工程建设管理的水平，支持我国的水利工程向更好的方向发展。本书从十章内容对水利工程建设管理进行介绍，内容详细，知识点全面。希望能够为推进我国水利事业的发展与进步。

Water is the source of life and the basis of human survival and social and economic development. However, with the rapid development of economy and the acceleration of urbanization, the increasingly serious pollution of water environment in China has seriously restricted the production, life and economic development of human beings. A series of prominent environmental problems such as water pollution and area shrinkage, eutrophication of rivers and lakes, and the degradation of ecological system, make the quantity of water resources and the quality of water environment become the key limiting factors of social and economic development in the future.
China is one of the countries with many rivers and lakes in the world. Crisscross rivers, scattered lakes, swamps and glacial snow fields on the top of mountains constitute a series of complex water systems. Because of the various and complex causes of water system formation and pollution, as well as the uneven spatial distribution of water resources and social and economic development, it brings great challenges to the
prevention and control of water pollution in China.
The State Council has issued Action Plan for Prevention and Control of Water Pollution ( hereinafter referred to as Ten Water Rules ). As a programmatic document in the field of water environment protection, Ten Water Rules defines the overall objectives, assessment indicators and key tasks of the prevention and control of water pollution in the future. At the same time, Ten Water Rules also clearly put forward “strengthen social supervision”, and the public is the core force of social supervision. Through the popularization of basic knowledge in the field of water environment protection, this book tries to spread the ideas, concepts and technologies of water environment protection in a simple and easy to form, so that the public can learn about the water environment, and then become the practitioner and supervisor of water environment protection, and effectively promote the work of water environment protection and management in China.
Due to the limited level and short time, there are inevitably some deficiencies in the
book. Readers are welcome to criticize and correct them.

前 言
水是生命之源，是人类生存和社会经济发展的基础。但是，随着经济的高速发展和城市化进程的加速，我国日趋严重的水环境污染问题对人类的生产生活和经济发展产生了严重的制约作用，水体污染与面积萎缩、河湖富营养化、生态系统退化等一系列突出环境问题的出现，使得水资源量和水环境质量成为未来社会经济发展的关键限制因素。
我国是世界上江河湖泊众多的国家之一，纵横交错河流与星罗棋布的大小湖泊、沼泽和绵亘于高山之巅的冰川雪原，共同构成了一系列复杂的水系。由于水系形成原因和污染成因多样复杂，加之水资源空间分布和社会经济发展的不均衡，给我国的水污染防治工作带来极大挑战。
国务院印发了《水污染防治行动计划》 （以下简称《水十条》 ） 。作为水环境保护领域的纲领性文件， 《水十条》明确了未来水污染防治工作的总体目标、考核指标和重点任务；同时， 《水十条》也明确提出要“加强社会监督”，而公众是社会监督的核心力量。本书通过水环境保护领域基本知识的普及，力图用浅显易懂的形式传播水环境保护的思想、理念和技术，使公众了解水环境，进而成为水环境保护工作的践行者和监督者，有效推进我国的水环境保护和治理工作。
