河湖清淤工程环境影响评价要点分析——以太湖输水主通道清淤工程为例

为深入了解河湖清淤工程对区域自然生态环境的影响，在对此类工程一般性环境影响特征分析识别的基础上，通过太湖输水主通道清淤工程这一典型案例，从工程分析、环境质量现状调查、环境影响预测方法、主评价结论5个方面对该工程环境影响评价工作点进行分析。结果表明，河湖清淤工程环境影响评价点与工程特征、环境特征密不可分，环境保护目标的分布及其敏感程度应当作为优先因素加以考虑，此外还应重点关注施工期间排泥场恶臭对大气环境影响、清淤活动对地表水环境及生态环境影响问题。

Analysis on Key Points in Environmental Impact Assessment of Lake and River Dredging Projects --A Case Study of Taihu Lake Water Conveyance Channel Dredging Project

To better understand the impact of lake and river dredging projects on the regional natural environment, this article first studies the characteristics of such impact. Then, by taking the Taihu Lake water conveyance channel dredging project for example, this article further studies the key points in environmental impact assessment of lake and river dredging projects from five perspectives, i.e. engineering analysis, environmental quality survey, environmental impact prediction and essential assessment conclusion. Finally, this article reaches a conclusion that key points in environmental assessment of the projects are inseparable from the features of both the project and the surrounding environment, and that priority concern shall be given to the distribution and sensitivity of the protection targets. During the construction, the impact of mud field stench on atmospheric environment and the impact of dredging activities on surface water environment and ecological should also be the key points.
