摘要: 云南永平金光寺省级自然保护区森林资源丰富,基于该保护区2019年林地调查数据及GIS技术,对该区域的森林资源现状进行分析和评价。结果表明:1)森林覆盖率较高,达96.21%,林地资源较为丰富,有林地占绝对优势;2)森林以天然林为主,占比达87.66%,活立木蓄积量较高,近140万m3;3)保护区乔木优势种以栎类为主,龄组以中龄林和近熟林为主。应加强保护区森林资源监测,掌握保护区森林资源的总体结构特点,为未来制定合理的管护方案和预测森林资源发展方向提供依据。Abstract: Jinguang Temple Provincial Nature Reserve is rich in forest resources.Based on the forest land survey data and GIS technology in 2019,the analysis and evaluation of the forest resources in this region show that:1) the forest coverage rate is high,up to 96.21%,and the forest land resources are rich,with the forest land taking the absolute advantage;2) the forest is dominated by natural forests,accounting for 87.66%,and the stock of living wood is relatively high,nearly 1.4 million cubic meters;3) the dominant species of trees in the nature reserve were Quercus,and the middle and near mature forests were the dominant species in the age group.The monitoring of forest resources in the nature reserve should be strengthened to master the overall structure characteristics of forest resources in the nature reserve,so as to provide a basis for making reasonable management and conservation plans and predicting the development direction of forest resources in the future.
