On the Construction of Water Ecological Civilization Driven by Ecological Water Conservancy Project

In recent years, China's traditional water conservancy projects are experiencing an unprecedented large-scale construction stage. Let's talk about ecological water conservancy projects to promote the construction of water ecological civilization.

Ecological water conservancy project has played a great role in ensuring social security, promoting economic development and protecting ecological environment, and it is a sustainable water conservancy project. By analyzing its characteristics, classification, importance and necessity of construction, the significance of typical ecological water conservancy projects in historical development is reviewed, and the important role of ecological water conservancy projects in the construction of water ecological civilization is discussed.

In order to implement the spirit of the 18th CPC National Congress, the Ministry of Water Resources proposed to speed up the construction of water ecological civilization, which is an important content of ecological civilization construction. The key to the construction of water ecological civilization lies in water ecological protection. Speeding up water conservancy construction and building ecological water conservancy has become an important content of water ecological civilization construction.

Water conservancy projects play a very important role in the construction of ecological civilization, which also puts forward more and higher requirements for water conservancy projects, and the development of ecological water conservancy projects is more rapid and epoch-making. Many people pay too much attention to the economic benefits brought by the construction of water conservancy projects, while ignoring the impact of the construction on the ecological environment. In the construction of water conservancy projects, how to realize the harmonious development of project construction and ecosystem protection, how to build ecological water conservancy projects and vigorously promote the construction of water ecological civilization is very important.

1 Difference between traditional water conservancy project and ecological water conservancy project

In recent years, China's traditional water conservancy projects are experiencing an unprecedented large-scale construction stage. People have met the growing demand for water supply, power generation, irrigation and flood control by developing, utilizing, transforming and harnessing rivers. However, the construction of water conservancy projects will affect the river ecological environment and terrestrial ecological environment to varying degrees, such as climate, soil environment, geology, river water quality and temperature, terrestrial environment and biology, human environment, forest and vegetation. We are facing the severe situation of shortage of fresh water resources and gradual deterioration of ecological environment, which is very inconsistent with the requirements of building a good ecosystem and developing ecological water conservancy in the construction of water ecological civilization.

Compared with traditional water conservancy projects, ecological water conservancy projects pay more attention to the protection, improvement or restoration of natural ecology, emphasize the construction goal of ecology and service ecology, pay attention to economy and environmental friendliness, and pay more attention to its ecological benefits. It can be said to accelerate the transformation from traditional water conservancy to modern water conservancy, ecological water conservancy and sustainable water conservancy.

2 the importance of ecological water conservancy projects in the construction of water ecological civilization

2. 1 typical ecological water conservancy project

Ecological water conservancy projects are divided into three categories: direct protection and improvement, substitution and synthesis. There are typical engineering cases since ancient times, which is of great significance. For example, the earliest water conservancy project to protect the ecology in China was Dayu's flood control and dredging of the Nine Rivers, which protected the ecology of the Yellow River basin and resisted the invasion of floods. The typical alternative ecological water conservancy project is the Lingqu built in the Qin Shihuang era, which connects Xiangjiang River and Lijiang River, solves the transportation of grain and grass, and plays an important role in unifying Lingnan. Sanqishui? The ecological protection of the original channel of Xiangjiang River has been realized in the following forms: Dujiangyan is a model of comprehensive ecological water conservancy project with a long history and remarkable benefits. It perfectly combines ecological environmental protection with economic and social development, realizes the harmony between people and water, and brings great economic, social and ecological benefits.

China built and utilized large-scale water conservancy projects in ancient times. At present, there are more and more ecological water conservancy projects with remarkable ecological benefits, such as water transfer from Tarim River, water transfer from Heihe River, water replenishment from Zhalong Wetland, construction of two rivers and four lakes in Guilin, construction of warping dams in northern loess areas, and construction of small hydropower stations.

2.2 the importance and necessity of ecological water conservancy project construction

With the continuous development of economy and society and the improvement of people's living standards, people put forward higher requirements for ecology. We should not only protect ecology, but also improve it, which requires us to build more ecological water conservancy projects. Ecological water conservancy projects not only efficiently develop and utilize water resources, but also properly protect environmental resources, which embodies the harmonious unity of man and nature, social and economic development and environmental protection, meets the needs of sustainable development of ecosystems, and constructs an organic combination of traditional water conservancy projects and modern ecology.

To promote the construction of water ecological civilization, it is required that all water control work should adhere to people-oriented, harmonious coexistence between man and nature and sustainable development, and properly handle the relationship between water control, water damage removal and ecological environment protection. The construction of water ecological civilization requires strengthening the protection and restoration of water and soil resources, the carrying capacity of water resources and water environment, and the construction of major water-saving and water-supply projects. The construction of ecological water conservancy projects plays an important role in optimizing the land development pattern, promoting resource conservation, maintaining the stability of ecological system and protecting the environment. Establishing the system guarantee system of water ecological civilization has become the top priority of water ecological civilization construction.

2.3 Requirements and measures for the construction of ecological water conservancy projects

2.3. 1 General requirements for ecological water conservancy project construction

The construction of ecological water conservancy projects should always follow three principles: protecting and restoring diversified rivers, maintaining and maintaining self-recovery ability, and aiming at restoring the whole water ecosystem. Man and nature live in harmony? And then what? Eco-environmental protection is a priority? Policy, give full play to the ecological and environmental benefits of water conservancy projects.

2.3.2 Specific measures for the construction of ecological water conservancy projects

? Proceeding from the reality of water conservancy, the essence of any water conservancy and hydropower project should be ecological engineering? . The construction of ecological water conservancy project is a complex project, which requires scientific layout, management and development projects, and comprehensive implementation of ecological environment protection measures for water conservancy projects.

The concept of ecological water conservancy should be integrated not only in the planning stage of the project, but also in all aspects of the project construction, which requires the project to meet the ecological requirements of the whole system and individual ecological design requirements. Meet the ecological requirements in the early planning, design, construction methods, management and operation of water conservancy projects, and strive to minimize the impact on the ecological environment. In engineering planning and design, engineering facilities must conform to the laws of hydrology and engineering mechanics, carry out content design in strict accordance with specifications, and organically combine with environmental engineering design. In the process of construction, priority should be given to eco-friendly technical measures to treat wastewater and waste residue, strengthen engineering environmental monitoring and protect the working area. After the completion of the construction, it is necessary to restore the completed land, and implement standardized management, scientific management and legal management, implement post-evaluation of the imported ecological water conservancy projects, and establish a monitoring and feedback mechanism for the impact of the projects on the ecological environment.

3 outlook

With the rapid development of social economy, people's demand for water supply is increasing, and the amount of sewage is also increasing. At the same time, in the face of serious pollution of ecological environment and shortage of water resources, it has become the main content of modern water conservancy construction to strengthen the protection of water ecology and water resources environment and promote the harmonious coexistence between man and nature. Ecological water conservancy project is an effective combination of water conservancy project and ecological construction, which can not only realize the development and utilization of water resources, but also protect and respect the natural ecological environment. This will be the inevitable trend of the construction and development of water conservancy projects in the future, which is of great significance to promoting the construction of water ecological civilization.
