| 在方竹水库的上、中、下游3个不同的水质区域设3个采样点,对浮游生物以及氮、磷、pH等指标进行检测和分析。调查数据显示,方竹水库的上、中、下游水体中的氮、磷含量及浮游生物组成和数量存在着明显差异。上游污染严重,中游存在人为施肥迹象,下游水体为Ⅲ类或近Ⅲ类水质。方竹水库自净作用明显,下游与上游相比,总氮含量下降19.74%,总磷含量下降68.81%,氮、磷富营养化指数分别下降3和19。浮游植物增加了1984.4倍,浮游植物多样性指数上升了0.32、均匀度指数上升了0.16、优势度指数上升了0.01;浮游动物增加了10.6倍。在整个水库水体中,总磷的富营养化评价指数远远大于总氮的富营养化评价指数。 |
| 英文摘要: |
| As it＇s revealed in the investigation data, significant differences of N, P concentration, as well as, the component and amount of plankton were absorved mong the upper, the middle and the downstream of Fangzhu reservoir. Upstream was seriously polluted, a obvious trait, namely artificial fertilization, was absorved in the middlestream,while, compared with the Water Environment Evaluation Criteria,the water quality of the downstream was located class IU, inferior conditions were detected also. This reservoir had exhibited a high Self-purification Capacity, compared with the upstream, the concentration of TN, TP, as well as the eutrophication index of N, P in the downstream were declined 19.74% and 68.81% ,3 and 19, respectively,while the biomasses of phytoplankton and zooplankton were tremendously increased 1 984. 4 and 10.6 times,respectively, as long as the phytoplankton diversity index, evenness index and dominance index,0.32,0.16 and 0.01 increases were observed, separately. In sum, the TP eutrophication appraisal index was extremely higher than that of TP in Fangzhu reservoir. |
