【摘要】 <正> 一、青岛近海的海草场海草场是遍布世界浅海水域最显著和广泛的群落类型之一.由于海草能利用根和根茎从基质中吸取和贮存养料,因而形成一个特有生产力的系统,碳的固定率几乎和热带雨林相似.海草为附生的微观藻类、硅藻和附着动物提供了一个理想的固着基层.作为沉积物和悬浮微粒的植被都存在于这一群落生境;此外,海草场也为小型动物提供了独特的微生境.青岛近海的海草场分布较广,见于胶州湾西岸的张戈庄、红石崖、黄岛,东岸的双埠、女姑口、沦口以及胶州湾口的薛家岛,市内沿海各区和大麦岛、石老人、姜戈庄等处,其中姜戈庄为虾形藻场,其余多为大叶藻场.虾形藻的主要组成种类是红须根虾形更多还原

【Abstract】 Seagrass beds are one of the characteristics of shallow coastal waters in tropical and temperate zones. Since seagrasses are green, photosynthesizing organisms occurring as mass vegetation, they must play an important part as primary producers.According to our own survey, the seagrass beds in the Qingdao coast are distributed in Jiangezhuang, Shilaoren, Maidao, Zhanshan, Taipingwan, Huiquanwan, Tuandao, Xuejiadao, Huangdao, Zhangezhuang and Hongshiya. One of them, Jiangezhuang seagrass bed, is a Phyllospadix bed and the others are all Zostera beds. The production of Zostera marina L. is estimated to be 564 gc/m~2 -year, while Z. ceaspitosa Miki 432 gc/m~2 -year, and Phyllospadix iwatensis Makino 696 gc/m~2 -year.In the general sense an epiphyt is any organism that lives upon a plant, whether or not a nutritional relationship exists. The present paper deals with flora and fauna epiphytic on both forms of seagrass beds in the Qingdao coast. At the end two appendices are attached where 266 species of seagrass and epiphyt are listed.更多还原
