中山大学海洋科学学院教授刘岚："海草床介于陆地和海洋中间，代表的是海洋当中三大生物多样性最丰富的生态系统，就是红树林、珊瑚礁、海草 床，这块沙滩的生物多样性非常高，海草床为生态系统提供了重要的营养来源，承担了初级生产力的地位，是食物链的底端。" 刘教授说海草往往长在海平面以下，退大潮的时候才能见到，加上形体纤细弱小，所以很难被人关注到。不知情的赶海游客在用铲子和耙子挖坑找海货 的时候，往往就把这些海草连根铲除了。记者在一片海滩上经过指点和仔细辨认，才拍下海草的模样。 央视网消息（焦点访谈）：赶海原本是沿海地区传承千年的一种生活方式。赶海时，渔民会在退潮后的滩涂和礁石区打捞或者采集一些鱼虾、贝类。记 者最近在一些海滩拍摄到一些赶海的人，他们并不是海边的渔民，而是专门赶海的游客。赶海已经被开发成旅游休闲的新项目，再加上社交平台的热推，吸 引了大量游客前往网红赶海地。游客蜂拥而至，同时也带来了简单粗暴的赶海方式。这么做的后果是什么？赶海体验与生态保护又该如何兼顾呢？ 今年暑假，珠海唐家湾沙滩作为社交媒体上的网红赶海目的地，吸引了大量的游客，每天有上万人来赶海。赶海原是海边渔民日常捕获鱼虾蟹的生产活 动，如今游客们模 ...
