| Abstract: | Huangshui River,the biggest grade one branch in upper reaches of Huanghe has 1.61 million hm2 of basin area in Qinghai province,the basin population accounts for 55.9% of the total provincial population,and total value of national production accounts for 48.4% of the total.The forest resource in the basin is limited and distributes unevenly.It also shows low unit stock volume,unreasonable forest age structure,low forestland use ratio and severe pest,disease and rat disaster.Owing to moderate ecological function and poor sustainable state of forest resource,the paper proposes the suggestions for the protection and management. |
