| 中文摘要: |
| 2010-2011年每2个月对河南南湾水库悬浮物进行了采样和分析。悬浮物现存量干重平均为11.93mg/L,有机碎屑是水库悬浮物的主要组成部分,占76.04%,浮游生物占24.96%。悬浮物无灰重为10.00mg/L;其中,有机碎屑无灰重的比例占80.45%,浮游生物无灰重占19.55%。悬浮物碳含量为7.43mg/L;其中,有机碎屑碳占84.70%,浮游生物碳占15.30%。悬浮物周年变化明显,其中7月和1月悬浮物的量最高;水平区域内,上游和库汊悬浮物量较大,中游和下游次之;垂直区域内悬浮物的变化不显著。悬浮物可以作为判断水库营养类型的指标,用悬浮物碳量估算的滤食性鱼类渔产力为49.5t。 |

| From 2010 to 2011，we take samples and analyzed the suspended solids every two months in Nanwan Reservoir in Henan Province. The average dry weight of standing crop of suspended solids was 11.93 mg/L which 76. 04% was contributed by organic detritus and 24. 96% by plankton. The no-ash weight of suspended solids was10.00 mg/L which 80.45% was contributed by organic detritus and 19.55% by plankton. The carbon content of suspended solids was 7. 43 mg/L which 84. 70% was contributed by organic detritus and 15. 30% by plankton. Annual variations of suspended solids are obvious that July and January showed the highest. In horizontal direction，suspended solids of upstream and library branch are greater，middle and backward part take second place，and there are no significant changes in vertical direction. TSS (total suspended solids)could be an indicator judging trophic types of reservoirs. The production potentials of filter-feeding fishes，which estimated from the carbon amount of suspended solids，are 49.5 t. |
