摘要
江湖阻隔是导致长江中下游江湖复合生态系统衰退的最主要原因,江湖连通和生物通道恢复是流域生态修复的重要措施之一.通过现场调查等方法研究了华阳河湖群、菜子湖、升金湖和安庆西江古道等与长江干流的阻隔现状及连通性特征,在此基础上探讨了技术和管理层面存在的问题并提出对策建议.结果发现:依托涉水工程建设开展恢复河湖生物通道的做法可以有效缓解江湖复合生态系统的衰退,尤其是以"过鱼设施建设、季节性灌江纳苗、生态水网建设"相结合的生物通道恢复方案具有技术可行性.相关成果可为长江中下游江湖连通性及生物通道恢复、国家水网建设提供有益的参考.
Abstract
The barriers between the rivers and lakes have been acknowledged as the main cause for the decline of the river-lake complex ecosystem in the lower-middle reaches of the Changjiang River.To restore the river-lake connectivity and biologi-cal corridors is surely one of the most important measures for its ecological restoration.In this study,on-site investigations were conducted at Huayang River as well as its affiliated lakes,Huayang Lakes,Caizi Lake and Shengjin Lake respectively,in order to investigate their connectivity to the main stream of Changjiang River.It was found feasible to perform the restoration engineering of the river-lake biological corridors by way of water conservancy projects,etc.,which could effectively slow down the decline of the river-lake complex ecosystem.In addition,a framework for biological corridor restoration was verified technically feasible,that is constructing fish passage facilities,building ecological drainage networks and seasonally flooding fries into lakes.Also,the research discusses the technical and managerial troubles that might exist as well as the countermeasures and suggestions.This study can provide useful reference for the restoration for connectivity of rivers and lakes and the biological corridors as well as the"State Water Grid Project"in the lower-middle reaches of Changjiang River.
