摘要：In order to understand variation characteristics of the soil available phosphorus and total nitrogen (TN) content around the roots of typical desert plantsPeganum harmalaLinn. (PHL) andAsterothamnus centrali-asiaticus(AC), which are widely distributed in Jinchang mining area of Gansu Province, the soil samples around the roots of the two plants were collected, and the contents of available phosphorus and TN were analyzed. The results showed that the change trend of soil available phosphorus content was not the same in the range of 0-60 cm around the roots of PHL and AC. In most areas the change of available phosphorus content in the soil from around the root of PHL was U-shaped, and the content of phosphorus around the roots of AC increased firstly and then decreased, while the change trends of TN content around AC was decreased gradually.
