水域生产力

渤海水域初级生产力10年间的变化

The Fluctuations of Primary Productivity in Bohai Sea Waters Over Ten Years

大型海藻构成近岸水域初级生产力的主要部分，其光合作用与生长受到多种环境因子的影响。

Macroalgae compose the important parts of primary production near the sea , and the photosynthesis and growth of which are affected by many kinds of environmental factors .

本文从热能转换的生态效率出发，结合水域基础生产力和渔获量变化趋势，论证了海洋再生资源的潜力；

In this report the marine renewable resource potential is demonstrated starting from the ecological efficiency of the heat energy change , and combining the primary production and catch change tendency .

根据我国沿海特点，建议我国今后对生物海洋学研究的重点是：1.对不同水域初级生产力的研究。

Based on the coastal features of China , we propose that the focal points of research in biological oceanography hereafter in China should be : 1 . Primary productivity studies in different sea areas ;

这些污水中包含了大量的有利于藻类生长的营养盐，氮、磷是藻类生长的必需的营养元素，他们构成藻类细胞的结构分子，并参与植物生长的新陈代谢，是水域的生产力的限制因子。

There are a large number of nutrients which is helpful to the growth of algae in the water . Nitrogen and phosphorus which form the structural molecules of algae cell and participate in the metabolism of plant growth are necessary for the growth of algae .
