Soil samples from soil layers of 0-10 cm

10-20 cm and 20-40 cm in Picea crassifolia forest were collected

and the soil physical properties

soil moisture content and soil nutrient was analyzed and determined for these soil samples.The results showed that the soil bulk density values from different soil layer were all below 1.00 g/cm3

but increased with the depth;Soil porosity showed the same trend

and the soil porosity of different soil layers were above 63% percent

indicating a good ventilation.With the depth

the soil water content decreased

with a lowest value of 18.7%.Soil organic matter and soil total nitrogen content have reached extremely high levels

soil nutrient level was marked as grade 1;Total potassium level belonged to level 2;The total phosphorus was deficiency and belong to level 4 or 5;Mean soil pH is 7.5.Suggestions were made to strengthen the effective protection and management of Picea crassifolia forest ecological system in the eastern Qilian Mountains.
