土壤作为森林生态系统的子体系,是林木扎根并赖以生存的基础,也是土壤微生物一切生命活动的场所.因此,有关土壤养分、水分及其土壤物理结构特征等方面的研究报告颇多(王政权等,2000;张合平等,1997).

The soil thermal regime and the effect of forest harvest in the watershed were studied in virtue of thermal conductivity equation in soil and physical principle by 6 years data in Chinese Fir plantation. The results showed that the content of water in the soil determined the change of the thermal capacity, thermal diffusivity and thermal conductivity according to the time in the watershed. With the increasing of soil thermal capacity, the percent of solid and the decreasing of porosity, all thermal factors increased. After forest harvesting, th...
