摘　　要：基于吉林省柳河县2019年森林资源管理“一张图”、三岔子林业局森林资源管理“一张图”和吉林哈泥国家级自然保护区的界线,利用ArcGIS软件,对吉林哈泥国家级自然保护区内的森林资源现状进行了分析和评价。结果表明:保护区内林地占保护区总面积的97%,森林覆盖率为93%。保护区森林资源以天然林为主,乔木林以阔叶混交林为主。林地活立木公顷蓄积相对较高,乔木林中中龄林、近熟林和成熟林所占比例较大,林木处于快速生长阶段,森林生态系统生态价值正在提升。保护区内针叶混交林、针阔混交林、阔叶混交林、灌木林地面积较大,生态系统服务价值较高。保护区内生态系统具有完整性和典型性,湿地生态系统和森林生态系统开发较低,部分区域仍保持着原始林分,有利于开展科学研究和生态系统监测。保护区内居民活动对生态环境产生影响。Based on“One Picture”of forest resource management in Liuhe County of Jilin Province in 2019,“One Picture”of forest resource management of Sanchazi Forestry Bureau,and the boundaries of the Jilin Hani National Nature Reserve,the status of forest resources in Jilin Hani National Nature Reserve was analyzed and evaluated with ArcGIS software.The results showed that the forest land in the reserve accounted for 97%of the total area of the reserve and the forest coverage rate was 93%.The forests of the reserve were mainly natural forests and the arbor forests were mainly broad-leaved mixed forests.The living wood growing stock per hectare in forest land was relatively high.Among arbor forests,middle-aged forests,near-mature forests and mature forests accounted for a relatively large proportion.Forest trees were in a stage of rapid growth and the ecological value of forest ecosystems was increasing.The areas of coniferous mixed forests,coniferous and broad-leaved mixed forests,broad-leaved mixed forests,and shrubs in the reserve are large.The ecosystem service value was high.The ecosystem in the reserve was complete and typical.The development of the wetland ecosystem and the forest ecosystem was low and some areas still maintain original forest stands.That was conducive to scientific research and ecosystem monitoring.The resident activities in the reserve had an impact on the ecological environment.
