| 摘 要： | 本文根据1993—2001年太湖站常规监测资料及2001-2002年周年实验资料，分析研究了太湖水体透明度的分布特征、季节变化，重点分析了透明度与光学衰减系数、悬浮物及叶绿素a的相互关系，阐述了影响透明度的主要因子。研究表明：太湖透明度的区域分布为湖心区最低，其次是河口区．东太湖最高；季节变化表现为全湖平均透明度夏秋季大、冬春季小，不同湖区变化不尽相同；光学衰减系数与透明度的关系为：Kd＝0．096 1.852/ST；悬浮质与透明度的关系为：S1/4＝8．103—5．847lnST；对透明度主要影响因子进行分析，发现太湖透明度主要受悬浮物的影响，透明度跟叶绿素的相关性不是很大，只存在微弱的线性相关。

| Abstract: | Based on the regular monitoring data from 1993 to 2001 and experimental data from 2001 to 2002, the distribution, seasonal variation of transparency, the relationship between transparency and beam attenuation coefficient, total suspended matter, and chlorophyll a and their influential factors are analyzed. The results show that the transparency is characterized by regional variation, being the lowest in the lake center and the highest in Dong Taihu lake; the seasonal variations of transparency are characterized by the fact that it is higher in summer and autumn, lower in winter and spring, with distinctions in different lake regions. There exits a relationship between the beam attenuation coefficient and transparency as follows: K d=0.096+1.852ST , and the relationship between the total suspended matter and transparency is found to be S 1/4 =8.103-5.847 ln ST . Because the transparency is mainly affected by the total suspended matter in Taihu lake, there only exits a slight linear correlation between the transparency and chlorophyll a. The main influential factors of transparency include total suspended matter and meteorological conditions. |
