Abstract:The present paper is dealing with the relationships between the growth of Pinus yunnanensis, of which stands were established by aerial sowing, and the soil conditions in the district of Liangshan, Sichuan Province, where there are many different types of soil such as mountainous laterite, sometimes in dark red colour, and yellowish red earth and brown earth and etc. Among those soils, mountainous laterite and yellowish red earth are more suitable for growing P. yunnanensis. Within the same type of soil there are some variations in depth, texture, pore size, amount of gravel and other physical characters by which the growth of the pine is significantly affected. The result of correlation analysis showed that,the growth of Pinus yunnanensis in height, diameter and volume was positively correlated with the depth of soil, and the pine stands growing on the loam contribute the greatest volumes compared with the other soils. It was also found that for this species the optimum bulk density was in 1.2—1.7g/cm3,porosity and gravel content around 36—55% and 10%, respectively.
