摘要: 对冀北高原闪电河水库上游20km长的河段的多介质体中总P含量及其动态变化分析表明,同源水体的总P含量各段不一,其中最高量(0.0824mg·L-1)为最低量(0.0228mg·L-1)的3.6倍;不同介质体总P含量以土壤(3402mg·kg-1)>淤泥(1992mg·kg-1)>岩石(542mg·kg-1)>水体(0.0553mg·L-1)的排序递减,并随温度升高而增高.

Abstract: The analysis on the distribution of phosphorus in water,sediment,rock and soil at the upper reaches of Shandian River basin shows that the total P content in waters from same source is different from site to site,the maximum amount being 3.6 times higher than the minimum one. In various media,the content of total P is decreased in the order of soil>sediment>rock>water,and increased with increasing temperature.
