【海带目】
海带目是褐藻纲之下一个目级的海藻分类单元，现时包括有约30个属date=November 2010。
这些海带生长于浅海海洋底下的海藻林：一种类似于陆地上森林的海洋植物群落，估计从中新世（即500到2300万年前）就已出现Reason=No such article now on linked site。
==分类==
本目包括下列各科art.tze.cn：
*厚岸藻科（Akkesiphycaceae）
*翅藻科（Alariaceae）
*绳藻科（Chordaceae）
*多肋藻科（）
*海带科（海带科）
*巨藻科（Lessoniaceae）
*拟绳藻科（Pseudochordaceae）
==生长和繁殖==
生长在分生组织基部发生。
==海藻林==
海带目聚集的地方会发展成被称为「海藻林」的海底森林，为最富有丰富生产力与多样性的地球生态系统。较小片的海藻林又被称为海藻床。在挪威海岸，有接近5800 km2的海岸就长满了海藻林Abdullah & Fredriksen，还为大量动物提及栖息地。
全球海藻林分布
海藻林分布于温带到极地地区的沿岸海域。在2007年，于厄瓜多附近的热带海域也发现有海藻林分布。
和热带的珊瑚礁一样，海藻林为许多生物提供生活环境，包括软体动物、甲壳动物、棘皮动物、鱼类及海洋哺乳动物等；同时也为人类提供生产力丰富的渔场。
==商业用途==
阿拉斯加州海滩的海带
巨型海带由于其表面的树冠和在较深水域停留的生长习性，可以相当容易地收获。
