摘　　要：滩涂海水种植 养殖系统是一种新型的生态养殖模式 .对种植红树林的滩涂种植 养殖系统中细菌的生物量分布和水质的分析结果表明 ,由于红树林的净化作用 ,该系统内的水质达到Ⅱ～Ⅲ类海水水质标准 ,而对照塘的处于Ⅳ、Ⅴ类水质标准 .系统中处理塘的异养菌、弧菌、磷细菌和产酶类细菌的数量比未种红树林的对照塘低 1～ 2个数量级 .用CORREL软件分析了细菌与水质的相关关系 ,异养菌、弧菌、磷细菌和产酶类细菌的数量与水体中的氮磷含量呈正相关 .其中异养菌与弧菌的相关系数为 0 92 0 5 ,与氮磷的相关系数为 0 6 5 35 (N)、0 8342 (P) 。ng system in inter tidal zone is a new type eco culturing model.The survey on bacteria biomass and water quality in the designed planting culturing system in inter tidal zone showed that the mangrove planted in the system improved water quality and made water quality to Ⅱ～Ⅲ type,better than the Ⅳ and Ⅴ type in the control pond.Designed ponds made heterotrophic bacteria,vibrio,phosphorus bacteria and enzyme producing bacteria populations 1～2 order lower than the control pond without mongrove planting.Correlation analyses with CORREL software showed that the biomass of these bacteria was positively related with the nitrogen and phosphorus contents in water of the system,and the correlation coefficient for heterogeneous bacteria and vibrio was up to 0.9205.Heterotrophic bacteria and vibrio could be used as the water quality monitoring organisms.
