以我国第八次森林资源清查(2009~2013年)青海省森林资源结果为基础,与森林资源第七次清查(2004-2008年)对比,系统分析了森林面积、森林覆盖率和森林蓄积量等指标动态变化过程,认为:天然林增加幅度较大,人工林建设速度加快,森林数量与质量明显提高,生态系统功能进一步增强,存在森林总量不足、林龄组结构不合理、分布不均、森林保护压力大、造林难度大成本高、森林抚育与病虫鼠害防治任务艰巨等问题。提出了青海省有效保护和建设森林资源,需要扎实推进国家公园体制试点、高效实施国家生态建设工程、加大造林力度和林业产业结构调整等对策建议。
Based on the results of forest resources in Qinghai Province during the eighth forest inventory (from 2009 to 2013) of our country and the seventh inventory (from 2004 to 2008) of forest resources, we systematically analyzed forest area, forest coverage and forest stock volume And other indicators of the dynamic process of change, that: a greater increase in the natural forest, plantation construction speed, forest significantly increased the quality and quantity, function of ecosystems to further enhance the existence of insufficient total forest, irrational age group structure, uneven distribution The pressure of forest protection, the difficulty of afforestation, the high cost and the arduous tasks of forest tending, pest, rodent control and arduous tasks. Proposed the effective protection and construction of forest resources in Qinghai Province, the need to promote the pilot national park system, efficient implementation of national ecological construction projects, increase afforestation and forestry, industrial restructuring and other countermeasures.
