Water is the foundation for the survival and development of human civilization, and is a strategic resource for economic and social development. In modern society, water is the core element of sustainable economic and social development and the progress of human civilization.
Rejuvenating water conservancy and removing water hazards has always been accompanied by human beings in the process of survival and development, from Dayu to Li Bing's father and son to build Dujiangyan, to the opening of the Beijing-Hangzhou Grand Canal, etc., the historical documents left behind are full of sweat, and there are many projects that have been preserved to this day.
After the founding of the People's Republic of China, from the Yellow River to the construction of the Three Gorges Dam on the Yangtze River, it marked that China's water conservancy and water hazard removal have reached a new historical high. Through the practice of water conservancy construction, people have not only gained a deeper understanding of the law governing the development of water conservancy, but have also continuously endowed water conservancy construction with richer connotations.
In the category of traditional water conservancy, water conservancy has always been regarded as the infrastructure for the national economy, especially for agriculture, ** once pointed out: "water conservancy is the lifeblood of agriculture", this assertion is very correct, for a long time, people under the guidance of this assertion, through vigorously strengthening the construction of farmland water conservancy and flood control projects, the infrastructure of agricultural production has been continuously consolidated, laying a solid foundation for the steady development of agriculture, especially grain.
With the continuous development of economy and society, people gradually jump out of the field of traditional water conservancy, is changing to the development of modern water conservancy, accompanied by the expansion of water conservancy connotation and extension, in addition to farmland water conservancy, disaster prevention and water conservancy, its connotation is richer, such as people's livelihood water conservancy, focusing on solving the problem of drinking water safety for urban and rural residents; For example, ecological water conservancy, focusing on solving the problem of ecological restoration; For example, the boundary river water conservancy focuses on solving the problem of homeland security; For example, shipping water conservancy, focusing on solving the problem of water transportation; Such as energy and water conservancy, focusing on solving the problem of electric energy and so on. Although there is no accurate conclusion on modern water conservancy, the author believes that compared with traditional water conservancy, modern water conservancy has at least the following obvious characteristics.
The first is public welfare. Public welfare is the basic attribute of modern water conservancy. Water is a kind of public resource, which determines that the development of water conservancy should focus on improving the public service capacity of water conservancy, put the public welfare of water conservancy construction in a more prominent position, and let the broad masses of the people share the fruits of water conservancy development.
The second is engineering. Without engineering, there would be no modern water conservancy. The development of modern water conservancy should be based on engineering and continuously promote the accelerated development of modern water conservancy through the planning and implementation of systematic and key water conservancy projects.
The third is scale. Traditional water conservancy projects are relatively simple and develop in a point shape, which is mainly reflected in a single project. Modern water conservancy is more embodied in the integration of projects, which are developed in a block-like manner, with a large number and scale, and a strong momentum of cluster development.
Fourth, industrialization. Modern water conservancy pays more attention to the role of the market in the allocation of water resources, regards water conservancy as a basic industry, and at the same time embodies the service function of the national economy, it also regards itself as a system of the national economy, and the same production products also create economic and social benefits.
Fifth, socialization. Modern water conservancy is not only limited to the field of agriculture, but has penetrated into all aspects of economic and social development, and the development of modern water conservancy determines the speed, quality and efficiency of economic life development to a certain extent. This is an obvious feature of the times of modern water conservancy. To sum up, the development of water conservancy has always been closely linked with economic and social development, and the development of modern water conservancy is not only the product of economic and social development to a certain historical stage, but also the inevitable choice for further economic and social development.
