湖泊清淤整治工程的生态风险评估与对策研究OA

Dredging project is one of the main engineering measures for controlling lake eutrophication,but its scien-tific basis and long-term ecological impacts on river-lake ecosystem remain controversial.Through analysis,this paper reveals the multiple ecological risks that may be associated with lake dredging projects,and proposes a com-prehensive management paradigm that shifts from"engineering-based lake treatment"to"ecology-based lake main-tenance".This paradigm is rooted in"source control"and centered on"nature-based solutions",emphasizes the measures including systematic diagnosis,zoning management,precise in-situ restoration and ecosystem reconstruc-tion with tailored strategies for each lake,long-term monitoring and adaptive management.The goal is to restore the self-purification capacity and health resilience of lake ecosystems,and provide a scientific,prudent,and reasonable approach for sustainable governance of lakes.
