摘要：

2008年6月13日和9月23日2次对石头口门水库进行光谱测量,并测定有色溶解有机物(CDOM)、总颗粒物质量浓度、叶绿素a质量浓度等水质参数,分析石头口门水库CDOM的光学特性以及季节变化特征,同时讨论不同季节CDOM吸收在水体各组分总吸收中所占的比重.6月份CDOM主要来源为路源,而9月份CDOM主要由浮游植物的光学降解形成;光谱斜率S与a_CDOM(355)具有稳定的对数递减关系;石头口门水库总体上是非颗粒物吸收和CDOM吸收占据主导地位,叶绿素a吸收比率最小.

关键词: 有色溶解有机物, 光学特征, 石头口门水库, 光谱斜率

Abstract:

Two experiments were carried out in Shitoukoumen Reservoir on June 13^th, 2008 and September 23^rd, 2008 separately and some important parameters of water were measured. CDOM mainly comes from the terrestrial source in June, while the degeneration of phytoplankton in September. There is a steady inverse relationship between S and absorption of CDOM at 355nm. The ratio of CDOM absorption varies with season.

Key words: CDOM, optical properties, Shitoukoumen Reservoir, spectral slope
