摘要
2016年某水库入库水中硝酸盐氮含量与往年有着明显的不同。研究该水库2016年硝酸盐氮年际变化,以及硝酸盐氮含量与大通站径流量及藻类生长之间的关系。结果表明:该水库库内外硝酸盐氮含量季节性变化明显,冬季>春季>秋季>夏季;库外硝酸盐氮含量受到径流量影响,随径流量增大而减小;库内硝酸盐氮含量受藻类生长影响较大,藻类生长越好对硝酸盐氮吸收量越大。
In 2016, the content of nitrate nitrogen in a reservoir was different from previous years. Annual changes of nitrate nitrogen in this reservoir, relationship among nitrate nitrogen content, algae growth and discharge in Datong hydrological station, were studied. Results showed that seasonal variation of nitrate nitrogen content in the reservoir was obvious. The content in winter is high- est, followed by spring, autumn and summer. Nitrate nitrogen outside of the reservoir was affected by discharge and decreased with the increase of discharge. Nitrate nitrogen in the reservoir was greatly affected by algae growth, and the better algae growth was, the greater the nitrate nitrogen absorbed.
