Abstract:

2002年1~2月,在南极普里兹湾及其北部海区对浮游植物生物量、优势种类组成、细胞丰度、初级生产力和新生产力的观测结果表明,叶绿素a浓度、初级生产力和新生产力的高值均出现在湾内及湾口陆架区,并且远高于陆坡和深海区.湾内和湾口陆架区表层叶绿素a浓度均高于1mg/m3,平均为(2.34±0.85)mg/m3,而陆坡区和深海区平均只有(0.19±0.14)和(0.15±0.05)mg/m3.湾内和陆架区平均初级生产力[(355.8±192.1)mg/(m2·d)]高于陆坡区[(82.0±20.8)mg/(m2·d)]和深海区[(100.5±83.4)mg/(m2·d)].在陆坡和深海区初级生产力的粒级结构以微微型浮游生物(<2μm)对初级生产力的贡献最大(分别为49.6%和46.2%),湾内和陆架区则以小型浮游生物(为20~280μm)的贡献为主(66.2%).在湾内和湾口陆架区同时具有较高的新生产力和再生生产力.
