With the national attention to agricultural economy, how to improve the quality of agricultural economic development has become one of the important contents of national economic development. From the actual development of China’s national economy, the agricultural economy occupies an important proportion and the development of agricultural economy is related to the overall development quality of the national economy. From the current development of agricultural economy, in order to improve the quality of agricultural economic development, it is necessary to make full use of rural resources. In addition to seriously analyzing the actual development situation of rural areas, it is also necessary to conduct in-depth research on the overall development status of agricultural economy. Through the analysis of the current situation of China’s agricultural economic development, we can see that circular economy has become a new mode of agricultural economic development, which has a huge role in promoting the agricultural economy and improving the overall development quality of agricultural economy. Therefore, we should pay enough attention to the circular development mode of agricultural economy, and actively seek innovation based on the existing development mode, so as to ensure the comprehensive development of agricultural economy and improve the development effect of agricultural economy.
In the process of agricultural economic development, in order to improve the quality of agricultural economic development, we must seriously sum up the experience of agricultural economic development, actively innovate the development mode of agricultural economy, adopt the development mode of agricultural circular economy, improve the overall development quality of agricultural economy, form the effective use of agricultural resources, and ensure that the development quality and level of agricultural economy are effectively improved.
Water is an indispensable and important material for human beings and all living things. It is also an irreplaceable and precious natural resource for industrial and agricultural production, economic development and environmental improvement. However, the shortage of water resources, flood disasters and water environment pollution are becoming increasingly serious, which forces human beings to pay attention to the protection and utilization of water resources and water environment. Water environment is one of the basic elements of the environment, is an important place for the survival and development of human society, and is also the most seriously disturbed and damaged area by human beings. At present, based on the evaluation of regional water resources, scientific researchers begin to study the rational planning, scientific management and effective protection of water resources from the perspective of optimizing the benefits of water resources system, so as to coordinate the water demand of water resources with the water resources carrying capacity of regional environment, and realize the sustainable utilization and coordinated development of water resources.
This book mainly describes the related knowledge of hydrology and water resources, and introduces the development, management and protection of water environment. The development of national economy and the improvement of human living standards are restricted by the state of water resources. The reasonable development and utilization, effective protection and management of water resources is an important guarantee to maintain the sustainable utilization and virtuous cycle of water resources, and also the key to maintain social progress and sustainable development of national economy. In the past decade, the situation of water resources in the world has been deteriorating, the shortage of water resources is serious, and the contradiction between supply and demand has become increasingly prominent. The direct causes are the blind and disorderly development and utilization of water resources, the unreasonable layout of development and utilization projects, especially the uncontrolled expansion of exploitation and utilization, poor management, and ineffective protection measures. Effective and rational use of water resources, protection and management of water resources has become an important research topic in the field of world water resources research.
本文主要讲述了水文水资源的相关知识，介绍了水环境的开发、管理与保护的内容。国民经济的发展和人类生活水平的提高受水资源状态的制约。水资源的合理开发利用、有效保护与管理是维持水资源可持续利用、良性循环的重要保证，也是维持社会进步、国民经济可持续发展的关键所在。近十几年来，世界范围内水资源状况不断恶化，水资源短缺严重，供需矛盾日益突出，产生的直接原因是盲目和无序地开发利用水资源， 开发利用工程布置不合理， 尤其是无节制地扩大开采利用量、管理不善、保护措施不力。有效合理地利用水资源、保护和管理水资源成为世界水资源研究领域的重要研究课题。
Water resource is a very important and special natural resource. It is an indispensable precious resource for human beings and all living things. It is an important condition to support the normal operation of life system and non life environment system. At the same time, it is also an important natural resource and material basis for the economic construction and social development of a country or region. If there is less water or no water, it will not be able to maintain the vitality of the earth and the ecological and biological diversity, and it will not be able to carry out various social and economic activities. Therefore, the abundant and dry water resources and the development and utilization of water resources affect the economic development and ecological balance of a region to a great extent, and the sustainable development of water resources is one of the components of the sustainable development of the whole society.
The sustainable development of water resources refers to the sharing of water resources not only with the present era, but also with future generations. It is not only the sharing of water resources by people, but also the sharing of water resources by people and the environment. It is an important guarantee to realize the sustainable development of water resources to reasonably and comprehensively consider the relationship among water resources, social economy and ecological environment, and reasonably allocate water resources.
Environment, including natural environment and human environment. Natural environment, composed of biosphere, atmosphere, hydrosphere and lithosphere, is the necessary geological condition for people's survival and development, and the sum of various natural factors around human beings. Human activities have a great impact on geology and environment, especially a series of reactions caused by over exploitation of groundwater. This book analyzes and discusses this.
