摘要
通过对 1997～ 2 0 0 1年阳宗海水质监测资料的分析 ,采用秩相关系数检验法得出结果表明 :总磷、总磷这 5年呈下降趋势 ,而高锰酸盐指数变化不明显 ,富营养化的威胁仍然存在。
Through the analysis of Yangzonghai leke water conditions from 1997 to 2001, we come to a conclusion by using coefficient of correlation check, it indicates that total phosphorus and nitrogen trends to decrease last five years, but hypermanganate exponent is not evident, the entrophication is still exist.
