Preface
At present, water resources are increasingly affecting the economic and social development and the improvement of ecological environment. The total amount of water resources in China is relatively rich, but the per capita share of water resources in China is low, and the spatial and temporal distribution is uneven, which does not match the land resources and economic layout, so it is difficult to develop and utilize water resources. On the whole, it is faced with serious drought and flood disasters, prominent contradiction between supply and demand, extensive water use methods, and great pressure on water ecological environment. With the continuous growth of population, acceleration of urbanization, economic and social development, improvement of people’s living standards and global climate change, the contradictions and problems of water resources in China will continue to intensify, especially in the northern region. Due to the influence of continuous drought and human activities, the problem of water resources is more prominent.
The problem of water resources and water environment is being paid attention to by all walks of life. Reasonable development and utilization of water resources, scientific treatment of sewage, and strengthening the management and protection of water resources have become an important means and guarantee measures for the sustainable development of human environment, economy and society. The protection of water resources and the treatment of water pollution are very important contents. Therefore, it is necessary to put the protection of water resources in a more important position. It is proposed to strengthen environmental protection, actively promote regional environmental governance of key river basins, urban sewage and garbage treatment, agricultural non-point source pollution control, comprehensive treatment of heavy metal pollution, and strengthening the development of water resources science and technology. The rational utilization and protection of water resources is not only a major strategy that must be vigorously developed and urgently promoted in our country at this stage, but also a common subject faced by human society
前 言
当前，水资源正日益影响着我国区城经济社会发展与生态环境改善。我国水资源总量较为丰富，但是我国水资源人均占有量低、时空分布不均，与国土资源和经济布局不相匹配，开发利用难度大，总体上面临着旱涝灾害严重、供需矛盾突出、用水方式粗放、水生态环境压力大等水问题。随着我国人口不断增长、城市化进程加快、经济社会发展、人民生活水平提高和全球气候变化，我国水资源面临的矛盾与问题会不断加剧，特别是北方地区，由于气候持续干旱和人类活动的影响，水资源间题更加突出。
水资源水环境问题正受到各界的关注和重视。合理开发与利用水资源，科学治理污水，加强水资源管理与保护已经成为当前人类维持环境、经济和社会可持续发展的重要手段和保证措施。水资源的保护和水污染的治理都是十分重要的内容，因此要把水资源保护摆到更加重要的位置，提出要加强环境保护，积极推进重点流域区域环境治理及城镇污水垃圾处理、农业面源污染治理、重金属污染综合整治、加强水资源科技发展等工作。水资源的合理利用与保护，不仅是我国现阶段必须大力发展和急需推进的重大战略，更是人类社会共同面临的课题。
