抽水型水库在进水期和非进水期因水动力和水体自净作用不同而具有不同的水质特征，水质指标在库区的分布存在差异。利用层次分析法分析水洞沟水库在进水期和非进水期不同采样点位的水质差异，结果表明：水库在进水期和非进水期不同区域的水质特征不同，各水质指标相对于水库总体水质的重要性亦不同。在进水期，库区不同区域水质指标的变化特征基本一致，TN、CODCr、TP 对水质的影响较大；在非进水期，磷沉降导致水中 TP 对水质的影响弱化，因此 TN和 CODCr对水库总体水质的影响较大。根据进水期和非进水期的水质差异，水库在水质管理和污染控制时应针对不同的控制目标采取水质控制措施。

For the difference of hydrodynamic field and water self-purification,there are different water quality characteristics between inflow phase and no-inflow phase in a pumped storage reservoir. Analytic hierarchy process was used to analyze the differences of water quality in different sam-pling points. The results show that the water quality in different areas of reservoir has different characteristics,and the importance of each water quality index relative to the total reservoir water quality is also different. In inflow phase,the changes of water quality indexes of different reservoir areas are almost the same,and TN,CODCr ,TP have stronger influence on the water quality;in no-inflow phase,phosphorus sedimentation leads to TP weaken influence on water quality,so TN and CODCr become stronger impress on the overall water quality of the reservoir. Due to the differ-ence of water quality between inflow phase and no-inflow phase,the solutions for water quality control should be carried out according to the water quality targets in different phases.
