摘要
根据洞庭湖河湖疏浚规划,通过对典型河段疏浚前后水情、水环境质量及承载能力变化的深入分析,定量与定性相结合对洞庭湖河湖疏浚的防洪减灾效益、水环境修复效益和生态系统恢复效益等进行了分析研究和预测。
Dongting Lake is an important regulating lake in the middle reach of Yangtz River. It receives volume and sediment of flood from Xiang River,Zi River,Yuan River,Li River and Yangtz River. This leads to get level higher because of deposit, disaster of flood becomes serious and environment worsened, capability of water self cleanseing and water environment bearing becomes lower.
