摘要
川蔓藻是近海生态系统中重要的初级生产者,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。本文结合我们在天津滨海湿地生态修复工程中对于川蔓藻的研究成果,从以下几个方面探讨了川蔓藻的生态学特征及其与环境的关系:川蔓藻对极端环境因子的适应;川蔓藻在资源分配上的繁殖策略;川蔓藻的矿质营养代谢以及对栖息地生物地球化学循环的影响;川蔓藻种群衰退的原因;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 an important elementary producer in the inshore ecosystem. Understanding its ecological characteristics is significant to restoring the degenerated and polluted coastal wetland ecosystems. We integrated a research on R. maritime to review and discuss its ecological characteristics from the following aspects： niche and adaptation with extreme environmental factors; propagation strategy in resource allocation; nutrition metabolism and impact on the biogeochemistry process; the reason of R. maritima declines in population; and application to environmental restoration. The organism＇s response to the environment changes greatly, and research into R. maritime has potential application in environmental engineering of water restoration.
