摘要:
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.

Abstract:
The suspended solids in Fuqiaohe Reservoir, Hubei Province were seasonally sampled and analyzed from 1998 to 1999.The mean amount of total suspended solids (TSS) in dry weight was 9.99l mg/L, among which 93.22% was contributed by organicdetritus and 6.78% by plankton. The no-ash weight in suspended solids was 3.45mg/L,among which 85.540 was contributed byorganic detritus and 14.46% by plankton. The contents of nitrogen and phosphorus in suspended solids of Fuqiaohe Reservoir were0.257mg/L and 0.0143ml,respectively,among which the contents of nitrogen and phosphorus were 0.200mg/L and0.0072 mg/L in organic detritus, respectively, and 0.057mg/L and 0.0071mg/L in plankton, respectively. TSS could be used asan indicator determining trophic states of reservoirs and could also be used to predict production potentials of planktivorous fishes.
Key words:  Fuqiaohe Reservoir  suspended solids  organic detritus  fish production potentials
