| 中文摘要: |
| ２００７年８月～２００８年４月，对三道河水库的水质进行调查，监测指标包括水温、透明度、浊度、总溶解性固体、电导率、ｐＨ值、溶解氧、总碱度、总硬度、总氮、总磷、亚硝酸盐氮、硝酸盐氮、氨氮、可溶性正磷酸盐、化学需氧量、氯化物、硫酸盐等。选取其中的总氮、总磷、溶解氧、化学需氧量、氨氮等５项水质指标，利用综合水质标识指数评价法（ＷＱＩ）对三道河水库水质进行评价。结果表明三道河水库水质达到国家地表水Ⅱ类标准，枯水期水质要好于丰水期，主要污染因子为氮磷营养盐。

| 英文摘要: |
| The survey of water quality on Sandaohe reservoir was carried out from 2007 to 2008. The monitoring indexes included water temperature, transparency, turbidity, total dissolved solids, conductivity, pH, dissolved oxygen, total alkalinity, total hardness, total nitrogen, total phosphate, nitrite nitrogen, nitrate nitrogen, ammonia nitrogen, orthophosphate, chemical demend oxygen, chloride, sulphate. Five water quality items which were total nitrogen, total phosphate, dissolved oxygen, chemical demend oxygen and ammonia nitrogen, were used to calculate the single factor water quality identification index of each item and the comprehensive water quality identification index （WQI） of 6 cross sections. The results showed that the water quality of the reservoir had reached class Ⅱ of ＂National Surface Water Quality Standard＂. The water quality of the reservoir in dry seasen was better than in flooding season, the main pollutants were nitrogen and phosphate nutrients. |
