摘要
黄河上游最大的一级支流湟水河,在青海省流域面积161.2万hm2,流域人口占全省总人口的55.9%,国民生产总值占全省的48.4%.该流域森林资源有限且分布不均;单位蓄积量低,林龄结构不合理;林地利用率不高,病虫鼠害严重.其生态功能中等,森林资源为弱持续状态.提出了保护和管理建议.
Huangshui River, the biggest grade one branch in upper reaches of Huanghe has 1.61 million hm^2 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.
