The comprehensive evaluation model based on matter-element analysis method was applied to evaluation of the forest soil nutrient in southeast of Yushu,with the soil organic matter,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus and available potassium chosen as evaluation indexes.Results indicated that the situation of forest soil nutrient in southeast of Yushu was favorable,but the available phosphorus became the limiting factor due to its poor content among the seven indicators.Forest type and forest community complexity had significant effects on available phosphorus (P=0.05).Available phosphorus content under mixed needle leaf forest and complex community structure was highest.Matter-element model presented its advantage in the process of assessment,and was an ideal method for soil nutrient evaluation.
