分别于2009年7～9月和2009年12月～2010年1月，应用15N稳定同位素示踪法，开展了中国东海和南海北部新生产力时空分布格局及其粒级结构的研究，同时从物理过程和营养盐输送等方面探讨了不同海域新生产力的季节变化及其调控因素，取得主要结果如下： 1.表层新生产力的空间变化特征 东海表层新生产力变化范围为0.053～4.060mgC•m-3•h-1，夏季平均值为1.093±1.192mgC•m-3•h-1，冬季平均值为0.330±0.303mgC•m-3•h-1。夏、冬季表层新生产力分布呈现不同变化趋势，夏季呈现近岸...Isotope 15N protocol was used to measure new production (NP) with size-fractionation in the East China Sea and northern South China Sea in the two cruises in July-September, 2009 and December, 2009-January, 2010, respectively. Temporal and spatial distribution patterns of NP and their controlling factors were investigated. The main results were as follows: 1. Surface NP (NPs) ranged 0.053-4.060 m...学位：理学硕士院系专业：海洋与环境学院环境科学与工程系_环境科学学号：2262008115154
