推动鄱阳湖生态保护与修复的思考及建议OA

As a crucial flood-regulation lake in the middle reaches of the Yangtze River,an internationally important wet-land,and a core node of the National Water Network,Poyang Lake has recently faced significant challenges in sustaining its ecological service functions due to the combined impacts of extreme climates and human activities.The key issues are reflec-ted in the following aspects:(1)The phenomena of"early dry seasons,prolonged low water levels,and drought reversal dur-ing the flood season"have becoming the norm.Submerged aquatic plants are gradually receding towards the center of sau-cer-shaped lakes,and the suitable habitat for the flagship species during dry seasons is gradually shrinking;(2)Agricultural source pollution within the lake basin is one of the primary drivers of water eutrophication;(3)The conflict of water supply use is acute among multiple sectors.There is difficulty in relying on existing major water conservancy projectsis to guarantee the eco-environmental water demand.Therefore,it is urgently necessary to establish a new system of governance,strengthen top-level design,and set up a unified management authority for the Poyang Lake basin.Additionally,scientific and techno-logical innovations must be accelerated,focusing on breakthroughs in key technologies for the comprehensive ecological and water management of Poyang Lake and its basin.This will enhance the ability of Poyang lake as a national water network hub,explore new pathways for transforming"Two Mountains"concept into practical action,and coordinate the synergistic development of water resources,food production,and ecosystems.The goal is to transform Poyang Lake into a smart,resili-ent,and symbiotic strategic hub within the national water network,and enhance the water security foundation of the Yangtze River Economic Belt.
