Abstract


The river training works is mainly to prevent flood in construction project. After the great flood of1998, the state invested a huge sum of money into the governance of river construction and all over the country lifted the river training construction of new climax. Traditionally river training play a huge role in protecting the country and the people’s engineering property plus safety of life, but its role in the protection of the ecological environment is also important. Although construction of river training works was improved to economic efficiency and the social efficiency, but the engineering construction to the influence of ecological environment and the ecological problems are becoming more and more outstanding.In the ecological environmental impact assessment of the river training works, the related theoretical studies and the actual evaluation work carried out late, evaluation methods and systems are still in the explore research, there are still many immature at. Firstly, Based on the ecological environmental impact assessment at home and abroad the research progress of the review and sort out the useful experience by drawing from the river training works at home and abroad according to the construction project environmental impact assessment and in accordance with the Environmental Impact Assessment Technical Guidelines For The Ecological Impact (HJ19-2011) the specific requirements of the basic theory of the impact assessment of the ecological environment of the river training works, such as sustainable development theory, niche theory, the theory of ecosystem diversity, biomes, succession theory, the limiting factor theory and evaluation methods are introduced respectively, such as analog analysis, a list of list law, eco-map method, biological productivity evaluation, landscape ecology method.On this basis, taking the Nanjing Xin Jizhou river ecological environment impact assessment for the example, this paper focus on the study of the status and construction of the terrestrial ecological environment of the area on the regional eco-environmental impact. Closely around the characteristics of impact of the river training works on the ecological environment, This article mainly analyze the terrestrial ecological environment problem brought by river training works, adopting various estimating method in drawing the conclusion. Through the analysis of these effects, minimal impact on environmental protection measures, construction and environmental management of river training works to provide a scientific basis for the ecological environment of the river training works.The significance of this thesis lies in:through the study on the terrestrial ecological environmental impact assessment of river training works, this dissertation summaried, complemented and improved the theories and methods of China’s river training works terrestrial ecological environment impact assessment at the first time. The theoretical study of the existing system, there are actual cases of scientific research, the lessons learned from case studies and the reference class river remediation work terrestrial ecological environment impact assessment of China’s ecological environment impact evaluation also there are some reference value.
