平陆运河内河段沿线河流水生生态影响识别

Identification of aquatic ecological influence along Pinglu Canal inland waterway

运河开发对区域交通改善和经济发展具有显著促进效应,然而其较大的开发强度和复杂的建设内容所造成的消极环境影响,已经受到越来越多的关注。针对运河水生生态影响的识别问题,通过对平陆运河内河段工程建设内容的分析归类,结合航道整治及航电枢纽建设的生态影响分析,采用类比分析、生态因子识别等方法,提出平陆运河内河段水生生态影响的3类重点评价内容,分析了建设内容对主要生态因子的影响,并从工程设计和生态修复两种维度梳理了水生生态保护措施体系。研究成果可为运河开发建设项目的生态环境影响识别与修复提供参考和借鉴。

Canal development has a significant promoting effect on regional traffic improvement and economic development.However,more and more attention has been paid to the negative environmental impact caused by its large development intensity and complex construction contents.Aiming at the identification of aquatic ecological impact of Pinglu Canal,through the analysis and classification of the construction contents of the inland waterway of Pinglu Canal,combined with the ecological impact analysis of waterway regulation and avionics junction construction,this paper proposes three types of key evaluation contents of aquatic ecological impact of inland river section of Pinglu Canal by analogy analysis and ecological factor identification,and analyzes the impact of construction contents on the main ecological factors.Further more,it sorts out the system of aquatic ecological protection measures from two dimensions of engineering design and ecological restoration.The research results can provide reference for the identification and restoration of the ecological environment influence in the canal development and construction project.
