Preliminary study on ecological project design

Way to repeated cycles manner. In this process, monitoring is the foundation. Monitoring, including biological monitoring and hydrological observations, early in the project need to establish a sound monitoring system for long-term observations. Also need to establish a system of river health assessment to assess the river ecosystem structure and function of the status and trends. Indirectly affect the ecological objectives,[link widoczny dla zalogowanych], and in the planning stage to give full consideration. However, the current design of many water conservancy projects have little or no ecological sensitive point to be considered. Another example is the implementation of flood protection in the Sanjiang Plain waterlogging early works,[link widoczny dla zalogowanych], some parts of the inter-basin water, such as the concentration of total dry duck cut Hung (1988 built) to the upper reaches of river runoff concentrated by ducks into the Green River Basin, Heilongjiang, rather than concentrated along the middle and lower river discharged into the reservoir and then into the great Canadian lakes in Heilongjiang, which makes the middle reaches of the Honghe National Nature Reserve Wetland 730km2 surface runoff due to reduced import, and to significant degradation of water resources, which are related to ecological sensitive point was not considered directly related. 3.3 The design of eco-hydraulic engineering and environmental engineering design combining ecological water projects should be designed to fully absorb the environmental science and engineering theory and technology, scientific distribution of water and water quality objective of sync, especially with the water pollution control should be organic combination works. The role of the hydraulic water generally larger and significant seasonal changes, so the design of eco-hydraulic design and implementation makes it possible there is a big challenge and resistance. In order to slow the dry mix the sediment or pollutants enter the drainage downstream of the lake or natural wetland into the lake or in the transition zone of the wetland design of ecological treatment oxidation pond or ditch. For paddy field drainage ditches can take advantage of the growing season, water storage, the use of artificial wetlands ditch the degradation of organic pollutants,[link widoczny dla zalogowanych], in fact, artificial canals in the storage conditions, if the slope of the growth of the two canals of aquatic vegetation, more significant treatment effect on water quality. Therefore, in the dryland rice cultivation, especially rice cultivation in areas of groundwater mining should be carried to the efficient use of water and water purification for the purpose of the ecological project design. This design ideas should come from the natural stabilization pond treatment of water pollution in theory and technology. Therefore, the ecological water conservancy and water pollution control project after the combination is an important ecological water conservancy development. 3 eco-project design the basic theory and method 4 Conclusion past 20 years, with the development of ecology, people have a new understanding of river management, recognizing that in addition to water conservancy projects to meet human needs of the community, but also to meet the maintenance of biological diversity of demand, the corresponding development of ecological engineering and theory. Ecological project design should follow the following three aspects of the theory and technology route. 3.1 The eco-hydrological and engineering as the basis for hydrologic analysis and calculation of hydrological processes will be applied to engineering design Ecohydrology is also rare in the current. This may be in the ecosystems of scientists do not engage in the actual design of hydraulic engineering. However, should attach great importance to the future eco-hydrology combination of hydrology and engineering, in order to provide the basis for the design of eco-hydraulic engineering. Serve as ecological water conservancy and broad, often involve wetlands, forest, grassland, agriculture, animal husbandry and ecological water rivers and lakes, and industrial, urban, fire,[link widoczny dla zalogowanych], residents and other economic and social life of water, the water so clear ecological goals resources, time and space requirements of the law in order to establish the ecological design of water projects on the basis of science. 3.2 The project should identify the likely impact of the key objectives of ecologically sensitive eco-hydraulic design should be able to be identified by the project directly or present, China is the construction of water conservancy and hydropower, exploration and development of eco-hydraulic engineering, the need to encourage multi-disciplinary cooperation and integration; need to actively learn from the experiences of developed countries, based on independent innovation. While also continue to improve project planning and design concepts and technology, engineering, based on demonstration and practice lifting theory, summed up the technical standards and specifications, exploration, development and eco-friendly project technology system.
