鄱阳湖五河及湖区生态岸坡及滨水带综合治理关键技术体系初探

鄱阳湖流域是长江生态系统的关键支点,在长江经济带发展中占有重要地位。面向鄱阳湖五河及湖区分布广泛的岸坡及滨水带区域,辨析了滨水带纵横向上的空间差异与存在的主要问题,提出生态防洪堤岸、生态水利血防、生态岸坡净化等单项关键技术的思路。通过分析单项技术的功能属性及其适用范围,明确了不同区域相协调的关键技术总体布局,初步构建了包括对象层、功能层、技术层、效果层和应用层的河湖生态岸坡及滨水带综合治理关键技术体系,为在鄱阳湖五河及湖区典型区域开展技术应用试验打下了基础。研究成果对其他类似河湖水系综合治理具有参考价值。

Preliminary Study on Key Technologies System for Comprehensively Managing Ecological Bank and Waterfront in the Poyang Lake Region and Its Five Major Tributaries

As a pivot in the Yangtze River ecological system, the Poyang Lake Basin plays a crucial role in the construction of the Yangtze River Economic Belt. The Poyang Lake region and its five major tributaries boast wide banks and waterfront zones. The spatial differences and major problems of waterfronts in vertical and horizontal directions were analyzed. On this basis, key technologies in ecological flood control embankment, ecological water conservancy combined with schistosomiasis prevention and control, as well as ecological bank purification were put forward. By analyzing the functional attribute and application scope of each single key technology, the overall layout of key technologies coordinated with different regions is defined. The key technology system includes object layer, function layer, technology layer, effect layer and application layer. The present research lays a foundation for technology integration and application in typical areas within the five tributaries and lake area of Poyang Lake, and also holds reference value for other similar rivers-lake systems.
