云南红河阿姆山省级自然保护区森林资源特征分析

利用阿姆山省级自然保护区2019年森林资源监测数据,从土地利用类型、林地结构、土地权属、森林起源、优势树种组成、龄组等方面分析了保护区森林资源现状特点,结果表明:保护区土地利用率高,类型较为丰富,林地面积占国土面积的92.36%;保护区森林资源极其丰富,有林地占国土面积的86.13%,天然起源的森林占森林面积的97.38%,保护区森林覆盖率高达86.35%;保护区森林组成树种较为丰富,其中面积占比较高的优势树种分别为栎类(55.09%)、其他阔叶类(24.76%)和云南松(15.86%);森林生产力较高,平均每公顷森林活立木蓄积量达104 m³;保护区中龄林面积占46.50%,幼龄林仅占3.69%,整体上树龄开始老龄化。为此,提出了相应的建议,以供参考。
