| 摘 要： | 作为饮用水源的小型水库四斗朱连续几年在早春即开始爆发严重束丝藻水华（属于蓝藻）。水质分析发现,四斗朱水库的水质参数如总氮（TN）、总磷（TP）、氨氮（NH4^＋-N）以及BOD和COD浓度并不高,但明显高于其上游的石门塘水库,这说明在四斗朱水库的集水区存在污染源。本文分析了在低营养盐浓度情况下四斗朱水库蓝藻水华爆发的原因,认为由于集水区内的农业、生活、水土淋失以及自然沉降等途径导致水库营养浓度升高。并由于未知营养、气温回升以及水库生态系统失衡等因素,导致蓝藻水华暴发。最后,提出了相应的综合治理对策。

| Abstract: | As the water source for drinking water supply,a small reservoir named Sidouzhu in Hubei Province was found having heavy Aphanizomenon(cyanobacteria)blooms broken out at every beginning of early springs in recent years. As shown by analysis,water quality parameters such as levels of total nitrogen(TN),total phosphorus,ammonia nitrogen(NH 4+ - N),BOD5 and CODMn all were not very high,but higher than those in another reservoir named Shimentang at its upper stream. It suggests that there have pollution sources ... |
