摘　　要：通过对南湾水库 6个采样点浮游硅藻分析 ,该水库硅藻 6 1个种及种下分类单元。用多样性指数 (H′)、均匀性指数 (E)及硅藻优势种生态谱分析 ,对水质进行了初步评价。结果表明 ,南湾水库水质属清洁 轻污染等级。An analysis of six samples in Nanwan Reservior indicated that there were 61 taxa of diatom.According to the Shannon-Wiener diversity index(H′).Lloyd-Ghelardi evenness index(E) and saprobiem spectrum analysis of dominant diatom species, the water quality of Nanwan Reservior was clean to slightly polluted.
