本文根据1989年4月至1990年1月秦山核电站邻近水域生态基线调查资料,对叶绿素α和初级生产力作了研究。结果表明,该水域潮流急,潮差大,营养盐丰富,悬浮泥沙含量高,且叶绿素α含量比较低。 光合作用同化数随季节而异,平均值为3.07mgC·mgchla~(-1)·h~(-1)。水域现场初级生产力主要受光和水体强烈混合的限制,平均值仅为27·00mgC·m~(-2)·d~(-1)。而季节变化明显,夏季初级生产力为60.14mgC·m~(-2)·d~(-1),高于秋、春两季,冬季最低,仅为2.31mgC·m~(-2)·d~(-1)。
Based on the survey data of the ecological environment of the adjacent waters of Qinshan Nuclear Power Station from April 1989 to January 1990, the chlorophyll a and primary productivity were studied. The results showed that the tidal current in this area had a large current and tidal range, rich nutrients, high suspended sediment content and relatively low chlorophyll a content. Photosynthesis assimilation numbers vary with seasons, with an average of 3.07 mgC · mg chla -1 · h -1. The primary productivity in the water area is mainly limited by light and water mixing, with an average of only 27 · 00mgC · m -2 · d -1. While the seasonal variation was obvious. The primary productivity in summer was 60.14 mgC · m -2 · d -1, higher than that in autumn and spring, the lowest in winter (2.31 mgC · m -2 · d) ~ (-1).
