长江中下游湖泊水生植被的生态水位管理策略

ECOLOGICAL WATER LEVEL MANAGEMENT STRATEGY FOR AQUATIC VEGETATION IN THE MID-LOWER YANGTZE SHALLOW LAKES

近年来,湖泊生态水文调控受到较大的关注,但有关水生生物的水文需求还缺乏系统研究。文章较系统地总结了长江中下游湖泊水生植物分布及水位现状、水位波动对水生植物的影响及水生植物的水位波动需求模式,介绍了以水生植物为指标的湖泊生态水位评估新方法,针对不同功能类型的湖泊,提出了相应的生态水位管理建议。

Eco-hydrological regulation of lakes have received more and more attentions in recent years,but systemic research on hydrological requirements of aquatic organisms is still limited.We systematically summarized the current status of aquatic plants and water level in the mid-lower Yangtze shallow lakes,influences of water level fluctuations on aquatic plants,and the requirement mode of water level fluctuation of aquatic plants.We also introduced a new method assessing ecological water level in shallow lakes based on aquatic plants,and provided corresponding strategies of water level regulations for lakes with different functions.
