在河口是一个结构复杂、功能独特的生态系统。陆地、海洋、大气在物理和生物等多学科、多因子变量间的交互作用,形成了基础生物生产力最高、生态功能脆弱和敏感、人类活动最为活跃的景观。如果说河口地区及其沿岸带是人口最为密集区,那么我们也不容置疑,水生生物栖息地随生态环 In the estuary is a complex structure, unique ecosystem. The interaction between land, ocean and atmosphere in multidisciplinary and multi-factor variables such as physics and biology has formed a landscape with the highest basic biological productivity, fragile and sensitive ecological functions and the most active human activities. If the mouth of the estuary and its coastal zone is the most populated area, then we also have no doubt that aquatic habitats with ecological ring
