摘　　要：川蔓藻是近海生态系统中重要的初级生产力。了解它的生态学特征对于河口海岸带的生态修复具有重要意义。本文结合在天津滨海湿地生态修复工程中对于川蔓藻的研究成果,从5个方面探讨了川蔓藻的生态学特征及其与环境的关系:(1)川蔓藻对极端环境因子的适应;(2)川蔓藻在资源分配上的繁殖策略;(3)川蔓藻的矿质营养代谢以及对生物地球化学过程的影响;(4)川蔓藻种群衰退的原因;(5)川蔓藻在环境修复中的应用。其中着重讨论了川蔓藻对环境变化的响应,并结合我们的研究工作展望了它在环境工程与近岸水体修复中的应用潜力。Ruppia maritime is the important elementary productivity in the offshore ecosystem. Understanding its ecological characteristics is significant to the restoration of degenerated and polluted coastal wetland ecosystem, we use our research findings on Ruppia maritime.L to review and discuss its ecological character from five aspects including （ 1 ） niche and adaptation of the extremely environmental factor, （ 2 ） propagation strategy in resource allocation, （ 3 ） nutrition metabolism and impact on biogeochemistry process, （ 4 ） reason why Ruppia maritima declines （ 5 ） application in the environmental restoration. Response to the environment changes is studied emphatically, and the research work on Ruppia maritia has looked forward to its potential applications in the environmental engineering and the nearshore waters restoration.
