Abstract

In this paper,analysis was made of the content changes of the soil organic carbon and water soluble organic carbon through different gaps (50 square meters,L1;100 square meters,L2;150 square meters,L3;control plot,CK) in typical low-efficiency spruce forest gaps of Miyaluo forest area in Western Sichuan.Dynamic monitoring was conducted on changes in soil organic carbon and water soluble organic carbon in four plots in different soil layers (0~15 cm and 15 cm~30 cm layers),and analysis was made of seasonal variation of soil organic carbon and water soluble organic carbon and thier relationship with other activated carbon and soil temperature.The results showed that total organic carbon and dissolved organic carbon content of the soil were L2 > L3 > L1 > CK,and those of the upper layer of soil were higher than those of the lower layer.In four seasons observations,water-soluble organic carbon content in the upper and lower layer soil was the lowest in summer,then gradually increased,and the carbon content of 100 square meters of forest gap was the highest.
