近年来,受全球变化及高强度人为干扰的影响,湿地退化严重（洞庭湖湿地枯水期提前、枯水期水位持续降低和浅水洼地减少）,导致洞庭湖湿地沉水植物大面积消亡.深入研究洞庭湖低水位对沉水植物的生长影响,对指导沉水植物恢复有重要意义.以我国典型通江湖泊洞庭湖典型沉水植物为研究对象,模拟野外沉水植物主要分布区域浅水洼地水文环境,设置4个水位梯度（25、50、75、100 cm）,探讨竹叶眼子菜（Potamogeton malaianus）、黑藻（Hydrilla verticillata）、苦草（Vallisneria natans）和金鱼藻（Ceratophyllum demersum）的生长、生物量和生理活性对水位变化的响应.结果显示:（1）前期底质养分含量为:...

Due to global changes and high-intensity human activities, serious environmental problems (e.g., the advance of the dry season in Lake Dongting wetlands, the continuous decline of water levels in dry season, and the reduction of shallow water depressions) have led to the large-scale extinction of submerged plants in Lake Dongting wetlands in the recent years. In-depth study of the effect of low water level on the growth of submerged plants in Lake Dongting is of great significance for guiding the restoration of submerged plants. We take the typ...
