| Abstract: | Taking 7925 forestland sub compartments from data of the forest resources survey on planning and design of Qinghai Province in 2009, and using analytic hierarchy process method, the soil thickness, soil type, slope, aspect and slope position were chosen as the main 5 factors of classification of forestland quality grade, the forestland were divided into I , lI ,III , IV levels . Respectively, forestland area are 9069.9 hm2 , 277221.5 hm2 , 81778.4 hm2 , 16576.0 hm2, accounts for 6.7% , 20.2% , 60.7% , 12.4% of the total forestland. Characteristics and distribution of all levels were described and protection, utilization and management measures were proposed. |
