Abstract:

1998-1999年按季度对湖北浮桥河水库悬浮物进行采样和分析.浮桥河水库悬浮物现存量干重平均为9.991mg/L,有机碎屑是水库悬浮物的主要组成部分,占93.22%,浮游生物仅占6.78%.悬浮物的无灰重为3.45mg/L,其中有机碎屑无灰重的比例占85.54%,浮游生物无灰重占14.46%.悬浮物碳为1.539mg/L,其中有机碎屑碳占81.46%,浮游生物碳占18.54%.浮桥河水库悬浮物氮、磷含量分别为0.257mg/L和0.0143mg/L,其中有机碎屑氮、磷分别为0.200mg/L和0.0072mg/L;浮游生物氮、磷分别为0.057mg/L和0.0071mg/L.悬浮物可作为判断水库营养类型的指标,同时也可用来估算水库滤食性鱼类的鱼产潜力.
