Abstract

Taking Daheiting Reservoir as an example, the water quality changes were studied by investigation and field sampling, and the water eutrophication and the main influencing factors were evaluated and analyzed in view of the gradually serious eutrophication of the water body in China. And the results were shown as below: DO concentration did not reach class II water standards only in the dry season. TN was inferior to class V in dry and normal season, and class IV in wet season; TP water quality was inferior to class V in dry and normal season, class III in July in wet season and not exceed the standard in August in wet season. CODMn exceeded the standard only during normal and wet water periods in August, and the water quality was class III. In dry season, the water body was slightly eutrophic; in normal water period, the water body was slightly to moderately eutrophic; in the wet season, the water body was slightly eutrophic in July and moderately eutrophic in August. Principal component analysis showed that temperature, nitrogen and phosphorus nutrients were the main influencing factors and do, pH and CODMn were the main manifestation factors of water eutrophication.
