Abstract: Cupressus gigantea is a precious species growing on the banks of Yaluzangbujiang River.The height may reach to 45 m and the diameter may be 420 cm.Four types of sites (Tc₁,Tc₂,Tc₃,Tc₄)were classified and the study was carried on each of site types with following results: Soil moisture,maximum water holding cappacity and total soil porosity decrease from top to bottam of soil profile;Organic matter and total N content are rich.There is accumulation of ash elements in litter layer obviously,Except B,the microelements,such as Cr,Ni,Co,Cu,Pb,Zn,Sr,Mo,and Cd,are higher in cotent than that in the soil of Zhumulangma Peak area.Except Cr,Ni,other microelements are higher than that of normal everage content of the world soil.
