Abstract

In order to understand the conditions of water soluble organic carbon (WSOC), 27 soil samples under Phyllostachys praecox stands in Linan were analyzed .The findings of analysis show that the content of 25 ℃water soluble organic carbon (25 ℃-WSOC )in the soil under Phyllostachys praecox stands is within (0.155 0 0.005 3)gkg-1 and that of 100 ℃water soluble organic carbon (100 ℃-WSOC)within (0.222 0 0.006 3)gkg-1 . The content and percent of WSOC in the soil under Phyllostachys praecox stands are both higher than those in the soil under tea and Chinese chestnut .The coverage measure to increase the temperature of the soil under Phyllostachys praecox stands increases the content of WSOC in the soil .The content of WSOC in the soil having been covered for 5 years in succession is double compared to that in the soil covered for only 1 year .WSOC in the soil under Phyllostachys praecox stands has obvious (P 0.05)very obvious (P 0.01)effects on the content of TOC , toal N , hydrolyzed N , available-P and rapid-K , activities of urease and surcease , Cd , Co , Ni , Pb and Zn in the soil , which indicates that WSOC organic substances have close relationship with the quality of soil .
