摘　　要：介绍了浮游植物生物量变化的研究方法。综述了南海北部浮游植物生物量在营养盐、光照、季风等理化因子影响下出现的变化特点。该海域生态环境复杂,由富营养的珠江口、沿岸带、北部湾和广阔的陆架及贫营养的开阔海区等不同生态区组成,因此浮游植物群落和生物量有其自身复杂的空间和时间变化特点。some advanced methods for studying phytoplankton biomass cycle are introduced in this paper. The characteristics of the phytoplankton biomass variation affected by the governing physico-chemical factors, such as nutrients, PAR, monsoon, etc. in the northern South China Sea （SCS） is also summarized. The northern SCS consists of various ecological zones, such as eutrophic Pearl River Estuary, coastal zone and Beibu Gulf （〈 50 m of water depth）, broad continental shelf （50 ～200 m of water depth） and oligotrophic open seas （〉 200 m of water depth）, which result in complex spatial and temporal patterns of phytoplankton communities and the biomass variation.
