摘　　要：根据 1999年 5月～ 6月的杭州湾现场调查资料 ,对杭州湾粪大肠肝菌及异养细菌的分布特点进行了研究 ,并分析了其与环境因子的相关关系。结果表明 ,杭州湾粪大肠肝菌数量分布主要受陆源性物质的支配 ,呈现西北高东南低的特征 ;而异养细菌则主要与浮游植物的数量有关 ,其分布特征为西南低东部高。与环境因子的相关分析表明粪大肠肝菌和异养细菌除均与水温、盐度相关较高外 ,前者还与无机磷、而后者则与叶绿素a呈现数量上的相关性。In this paper, the distribution of feal coliform bacterial and heterotropic bacteria in Hangzhou Bay, and the relationship between the biological abundance and the environmental factors have been resarched based on the data got from the field, May to June 1999. The results show the distribution of feal coliform bacteria with charateristics of the northwest higher and southeast lower, which mainly influenced by continental matter, while the distribution of hetorotropic bacteria in the east was higher than the southwest and actively coincidence with phytoplankton in the bay. Furthermore, the analysis of correlation between the bacteria and the environmental factors showed that feal coliform bacteria and heterotropic bacteria have obvious relativity with inorganic phosphorus and chlorophyl a respectively beside both of them were actively coincidence with water temperature and salinity.
