| 摘 要： | 对尹府水库进行野外取样和室内实验,运用综合营养指数进行评价,结果表明枯水季营养程度略高于丰水季,全年处于中营养状态,接近轻度富营养。进行水质分析显示：在时间变化上,枯水季节营养物含量明显高于丰水季节,枯水季总氮含量是丰水季的3.5倍,氨氮含量是丰水季的2.3倍,总磷含量也比丰水季高,而溶解氧的季节变化不大;在空间变化上,水体总氮和氨氮呈现水库入口大于出口大于库中的变化规律,水体磷含量的空间差异不大,出口和库中磷含量略微高些,入口磷含量略低。

| Abstract: | The field investigation and laboratory experiments were conducted on Yinfu reservoir.The integrated index indicated that Yinfu reservoir was under the moderate eutrophication status.The experiment result showed that the content of each nutrient in the dry season was higher than in the rainy season.The total nitrogen content and ammonia content of the dry season is 3.5 times and 2.3 times higher than the rainy season,respectively.In the dry season,total phosphorus was also higher.The dissolved oxygen had little different in each season.On the spatial variation,both the total nitrogen and ammonia showed that in the reservoir entrance the content was highest and in the export the content was lowest.The total phosphorus had not obvious difference in different locations. |
