The Eco Water Systems in traditional river management work focus on water control, and the purpose is to meet a series of functions such as shipping, water supply, power generation, and flood control. With the gradual increase of the population in social development, the contradiction between population growth and water supply has become more and more prominent.
Here are the articles to explain, Eco Water Systems Conservancy in River management
The rational use of water resources and the sustainable development of human beings have become issues that must face. River management has an old past in China. This article briefly expounds on the application of ecological water conservancy in river management engineering.
Eco water systems conservancy or protection
Ecological water conservancy refers to a way of using water resources, and it is a new understanding of resource utilization in the development of human civilization to the ecological Ming era, and its essence reflects sustainable development. The construction of ecological water conservancy is based on several necessities.
- The first is the needs of the ecosystem itself. An important factor for organisms is the existence of water resources, and also the circulation process of natural substances requires water to participate in it. Only the good development of the ecosystem can provide an effective guarantee for human development.
- The second is the requirements of the actual environment. In the past, people did not have a scientific understanding of the utilization of water resources, which led to a certain degree of waste and pollution, which had a serious impact on the environment.
- Finally, in the previous water conservancy work, human beings themselves existed not considered as part of the environment. Also, They unilaterally demanded the environment, causing serious damage to the environment in the basin.
Problems existing in current water conservancy projects
(1) Diversification of artificially altered rivers
In the process of utilization of water resources, the natural form of the river ignore, and the river stands artificially transformed. Furthermore, This leads to the change of the original layout of the river, and the local ecological environment formed by the river itself affect. For example, the disappearance of wetlands and the increasing scarcity of aquatic resources. The ecology of rivers forms in the long-term development process, and it is difficult to restore effectively in the short term for human transformation activities. Biodiversity will damage to a certain extent.
(2) Impact on the environment in the basin
The river forms a local small environment in the river basin, in which various elements present a virtuous circle, and human activities have changed the original circulation pattern. At the same time, after the development of the river, no attention stood paid to the restoration of biological populations. Also, the shoals and wetlands in the river basin stood replaced by modern facilities under the effect of economic benefits. Which formed obstacles to the water cycle.
The difference between eco water systems conservancy and traditional water conservancy projects
The differences between ecological water conservancy and traditional water conservancy projects are mainly in the following aspects. Scope, resource utilization, management work in the later stage of governance, principles, development of water functions, governance of river channels, and construction of embankments. It can be intuitively felt through the chart.
Application of eco water systems conservancy in river management projects
(1) Concept
Concepts guide human behavior. The application of ecological water conservancy must first establish the concept of sustainable development, recognize the damage to the environment caused by traditional water conservancy projects, and the development of human civilization and environmental development is unified. In the natural environment, human beings are a part of the cycle.
For the natural environment, it is necessary to change the previous single demand and transformation but to make reasonable use of it and live in harmony with nature based on protecting the environment. Water conservancy projects do not only reflected in flood control and water supply but also play a role in ensuring social development. To improve the ecological environment, the construction of a water environment is part of the construction of ecological civilization. It is necessary to recognize the national conditions.
In general, my country’s water resources are lacking. Without resources, social development cannot discuss. From the perspective of the history of human development, most of the birthplaces of quasi-civilizations are in large river basins. Water resources are the guarantee of agricultural production in the agricultural era and the foundation of social development in the industrial civilization era. The utilization of resources should include in the overall situation of social development. Consideration should take to improve the effective utilization of water resources.
(2) Method
A Revetment works. There is no fixed method for ecological water conservancy, and each region should respond flexibly according to its situation. There are several aspects to consider during the construction process.
The first is to effectively combine the flood control function with the optimization of the water environment, rationally arrange the layout, maintain the ecological environment along the river basin, and provide a guarantee for the sustainable development of the river bank.
The second is to consider the environment’s carrying capacity in the river basin. The natural environmental conditions in the river basin determine the environmental carrying capacity. Therefore, it is necessary to optimize the allocation of water resources in the process of utilization.
The third is the protection of aquatic systems. Furthermore, This work is a comprehensive large system, which reflects many aspects. Ecological embankment. The embankment stands mainly protected by plants, such as willow, poplar, reed, and calamus, and the embankment reinforces with plant roots. Natural revetment. The bottom protection makes of natural materials, the slope angle is artificially set up with bank protection, and also the slope surface is planted with vegetation. Artificial revetment. This model is based on natural bank protection, supplemented by certain artificial materials, and also mainly used for river sections with high flood control requirements.
Other things
One of the purposes of the dredging water conservancy project is flood control. Furthermore, The river needs to clean regularly during the artificial development process. The cleaning work should consider from an ecological point of view, such as the treatment of silt. Underwater operations will have a certain impact on aquatic organisms. So it is necessary to strengthen environmental monitoring during the work.
River wetland development Wetland knows as the kidney of the earth and is an important part of the ecological environment. The size of the wetland area directly affects the functioning of the ecological environment in the region. For the wetlands along the rivers, protection should be given priority. And for the inevitable development, planning should be done to combine economic and environmental benefits. Protecting the environment is the result of protecting the development of human civilization.
Degraded river belt Restoration river belt refers to the part between the high. And low water levels of the riverbed, including the submerged riverbed and the new and new tidal flats. The restoration work mainly includes the following aspects. The first is biological restoration, artificial introduction of related species, and promotion of population development through a series of protection measures. The second is environmental restoration, which is mainly to improve the local environment. And also improve the stability of the environment through a large number of greenery.
Conclusion
The application of eco water systems conservancy in river management is mainly the construction of the ecosystem. The rational allocation of water resources is based on meeting basic water consumption. And also the comprehensive management of the river environment. The essence of ecological water conservation is the harmonious development of man and nature. Which embodies the concept of sustainable development. For the utilization of water resources, the laws of nature should be respected. The economic and ecological benefits should be organically unified.
