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．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.
