摘要
海草床具有重要生态服务功能和经济价值,其生态修复成为沿岸环境工程的重要内容之一。但日本大叶藻(Zostera japonica)的生态功能与保护在东西方科学界却倍受争议。日本大叶藻不仅在形态上与同属物种有着明显的区别,生长与繁殖具明显的纬度效应,进化出多种环境适应机制。其资源分布在太平洋两岸呈现相反趋势:在原产地,资源衰退,是重点保护物种;在北美沿岸地区,分布区域不断扩展,给当地的生态系统和经济发展带来负面影响,成为入侵物种。密切跟踪日本大叶藻资源动态、甄别其生态功能和制定科学的管理措施将成为今后研究的重点方向。
Seagrass bed provides a variety of ecological services and economic values, and its ecological restoration has been one of the important coastal environmental engineering. However, the ecological functions and protections of Zostera japonica are controversial focuses between the western and eastern scientists. Z. japonica, known as dwarf eelgrass, shows obvious differences in morphology with other species of the same genus and the latitude effect of growth and propagation, evolving a series of envi- ronmental adaptation mechanisms. The resource distribution presents the opposite trends in the east and west coasts of the Pacific. Z. japonica has been a threatened species in native area, but it is recog nized as an invasive species in the coastal areas of North America. The expanded distribution has been bringing negative impacts on the local ecosystem and economic development. Closely tracking Z. ja ponica resources dynamic, screening its ecological functions and the development of scientific manage- ment measures will be the focuses of future research.
