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.

Key words: Phosphorus content, Upper reaches of Shandian River basin, North Hebeiplateau, model evaluation, population dispersal, Pomacea canaliculata, risk analysis., biological invasion, adaptability
