Nowadays, with the continuous development of economy, water conservancy construction is no longer limited to improving people's awareness of environmental protection. At the same time, pay more attention to improving people's living environment and protecting the natural environment. Integrating ecological concept into water conservancy design to promote the sustainable development of water conservancy projects. As the core of water conservancy construction, ecological technology is also of great significance to solve environmental problems and the main means to build ecological rivers. Now people have gradually accepted the integration of ecological concept into water conservancy design as the main way to develop ecological engineering buildings.
The significance of integrating ecological concept into 1 water conservancy design
Improve the ecological environment
As a way to realize the rational allocation of resources, water conservancy project construction uses science and technology to realize the storage, distribution and reuse of water resources, and uses science and technology to realize the rational allocation of water resources to arid and water-deficient areas. Therefore, while considering human needs, we should pay more attention to improving the ecological environment. Let water conservancy projects and ecological security be integrated with the development of human living environment, and realize the harmonious coexistence between man and nature.
Enhance ecological concept
In water conservancy projects, designers should not only bear the responsibility of engineering design, but also have relevant scientific knowledge of ecological protection. Through the professional training and on-the-spot investigation of engineering designers, environmental inspectors and managers, the demonstration role of nature protection consciousness is realized. Through the construction of water conservancy projects, disasters brought by natural environment can be prevented, such as soil erosion, river siltation, dam break and so on. Provide a strong guarantee for the ecological environment.
Realize the sustainable development of natural resources
Through the control and utilization of flood, the traditional concept is changed, and the idea of integrating water conservancy design into ecology is better reflected. At the same time, solve the problem of water shortage in some areas. And through the combination of water conservancy design and ecological concept, fully stimulate the clean ability of nature and strengthen the significance of protecting water resources.
2 water conservancy design into the ecological concept
Lack of information
The main purpose of integrating ecological concept into water conservancy design is to ensure that the local natural environment will not be destroyed while building water conservancy projects. Before the design of water conservancy projects, it is necessary to conduct on-the-spot investigation or find corresponding data to understand the local ecological environment, so that the ecological concept and water conservancy projects can be better integrated, popularized and brought into play. However, due to the lack of hydrological data in practical work, the staff can't start, which also causes the integration effect of ecological environment in water conservancy design. The lack of information makes it impossible to accurately grasp the local ecological situation, which leads to the accuracy of water conservancy designers' judgment and the impact of water conservancy design on the local ecological environment.
Designers lack relevant awareness.
On the basis of ensuring social life, promote local economic development and rational utilization of water resources. However, because designers attach too much importance to the economic function of water conservancy projects, it is easy to ignore the purpose of harmonious development of water conservancy projects and ecological environment, which leads to the failure to realize the real purpose of water conservancy projects to protect the ecological environment. Therefore, with the increasing diversification of water conservancy projects, we should constantly put forward more requirements for design work. Improve the designer's awareness of environmental protection, so as to better integrate water conservancy design with ecological concept, and also solve the application value of ecological concept in water conservancy design.
3 Basic principles of ecological water conservancy design
Economic security principle
The design of ecological water conservancy project should first follow the basic principles of water conservancy project and reach the basic principles of ecology, so as to improve the economy and safety of design scheme. Designers need to comprehensively consider the characteristics of erosion, sediment, sediment transport and river erosion, and also make a rigorous comparative analysis of water conservancy projects from the perspective of economic rationality, so as to reduce construction costs and ensure the maximization of economic benefits.
Principles of self-organization and self-recovery of ecosystem
Self-organization of ecosystem refers to natural selection among species, through which their species can find their own living environment and ensure their normal reproduction. Choosing reasonable species according to the self-organization and self-recovery ability of ecosystem can show the diversity of biological species, promote the self-recovery function of their species, and achieve the important purpose of water conservancy design.
3.3 the principle of maintaining and restoring the spatial heterogeneity of rivers
Biodiversity is closely related to the spatial heterogeneity of biota and abiotic environment. The complexity of biological environment space shows that there are many kinds of organisms. The design of water conservancy projects should ensure the good survival of abiotic and biotic groups. Create a good environment in the limited river ecosystem.
4 the application of ecological concept in water conservancy projects
1) The water storage capacity of water conservancy projects not only brings convenience to urban residents, but also solves many problems brought by the ecological environment. It not only satisfies their living conditions, but also allows them to better enjoy the pleasant mood brought by the ecological environment. In terms of river ecological design, it is mainly divided into two aspects: a. Regarding river regulation, before re-planning, the ecological environment of the river should be investigated in order to adjust measures to local conditions. B. Make scientific and reasonable solutions to other problems such as river positioning in combination with local natural conditions. In order to ensure the true value of the river and realize the harmony between man and the ecological environment, we must persist in retaining the self-repair ability of the river basin ecology.
2) Water conservancy engineering services are not limited to water supply, but also meet the requirements of greening. Therefore, only by clarifying the allocation and basic requirements of water resources can we serve more people. According to the data, a water conservancy design and research institute in Zhejiang Province made a comprehensive evaluation and consideration from the ecological hydrology in the process of undertaking a wetland ecological reconstruction project. During the implementation of the project, according to the needs of customers, an ecological water conservancy design scheme is put forward to replenish water for wetlands in non-irrigation period or intermittent irrigation period, and to replenish water for degraded wetlands by using tail water of irrigation area. This has become a typical case of ecological water conservancy in recent years, which not only meets the needs of agriculture, but also plays a role in restoring ecology in wetland water supply.
3) In order to minimize the unnecessary impact of water conservancy projects on environmental factors, designers will accurately identify key ecologically sensitive targets. In order to avoid future threats to the ecological environment due to negligence. Only by paying special attention to key ecologically sensitive targets can we greatly reduce the adverse impact of water conservancy project construction on the ecological environment and ensure the health of human living environment.
5 abstract
Considering that water conservancy projects have the dual nature of ensuring basic energy, reducing natural disasters and adverse effects on the ecological environment, integrating ecological concepts into water conservancy projects can not only improve its social and economic benefits, but also strictly control the balanced development of ecology. Realize the ideal of economic and environmental development and progress. It also magnifies and expands the role of the integration of water conservancy construction and ecological concepts. Realize the harmonious coexistence of human development and original ecology in a real sense, and let people accept the integration of water conservancy design and ecological concept. This is the real livelihood infrastructure and urban economic lifeline.
