| 摘 要： | 2007年2～5月在三峡水库香溪河库湾及其支流布置了17个断面,对藻类生长指标叶绿素a、相关环境因子及水动力因子进行同步监测,据此分析水华期间叶绿素a浓度和相关环境因子的动态特性.结果表明,香溪河库湾在监测时段内属于重富营养水平,库湾内叶绿素a、环境因子及流速分布具有较显著的空间差异,香溪河的藻类生长可能主要受NO3-N和SiO3-Si的影响,各分区对藻类生长有显著影响的因子各不相同.香溪河库湾流速较小,藻类在香溪河的生长体现出较大的空间异质性,而这种空间异质性与流速的空间的差异性有着较显著的相关关系.

| Abstract: | Chlorophyll a,environmental and hydraulic parameters were monitored in the Xiangxi River Bay and its branch of the Three Gorges Reservoir during February to May of 2007.From these,dynamic characteristics of Chlorophyll a concentration and other factors were analyzed.It is shown that the Xiangxi River Bay was at high eutrophication level.Chlorophyll a concentration,environmental parameters and flow velocity have significant spatial differences in the bay.NO3-N and SiO3-Si may be the key factors impacted on algal growth;and there were different key factors in different groups.Flow velocity in the bay is small;and the spatial differences of algal growth is related to similarity in the spatial differences of flow velocity. |
