The paper dealt with soil nutrients of a Chinese firstand after clear cutting in Yunyong Forest Farm based on the determination of soil pH value, soil organic matter, hydr olyzable nitrogen, available phosphorus, and available potassium in 0) 100 cm layer in October, 2004 and April, 2005. The study may provide a scientific basis for Chinese firstand reforestation and site productivity maintenance. Compared with all the soil layers in 2004, the pH values of all the soil layers in 2005 decreased; the contents of soil organic matter and available potassium and the contents of soil available phosphorus except for 0) 5 cm increased; and the contents of hydrolyzable nitrogen increased in some soil layers and decreased in other soil layers.
