【摘要】 结合牡丹峰自然保护区的资源现状，选定阔叶红松林设置大样地进行了森林资源监测，小样地进行了生态功能监测。监测样地初期为2019年，复测期为2022年，监测期3年。调查研究表明：通过两期对比分析，平均胸径增长了2.93 cm,总株数减少120株，碳储量增加4.3844 tc,蓄积量增加8.7864 m~3。生态功能等级评定为中等，森林的健康等级略有下降，但仍稳定在健康标准内。森林灾害面积增加了74.96%。生态功能指数变化差值为-0.04。森林生态功能本期较前期向中、差的方面发展，森林综合生态功能有变弱趋势。提出了保护区森林群落固定样地监测工作是一项长期任务，保护区管理应加大力度，严防社会闲杂人员对保护区的资源的破坏行为，为保护长期生态监测奠定必要基础。更多还原

【Abstract】 Combined with the resource status of Peony Peak Nature Reserve, the broad-leaved red pine forest was selected for forest resources monitoring and ecological function monitoring for small samples. The initial monitoring of the sample plot is 2019, and the retest period is 2022. The monitoring period is 3 years. The survey showed that through the comparative analysis of the two phases, the average breast diameter increased by 2.93cm; the total number of plants decreased by 120 plants; the carbon storage increased by 4.3844tc, and the stock increased by 8.7864m~3. The ecological function rating was average, and the health level of the forest decreased slightly, but remained stable within health standards. The area of forest disasters increased by 74.96%. The difference in the change of ecological function index was-0.04. Compared with the previous period, the ecological function of forest has developed to medium and poor aspects, and the comprehensive ecological function of forest has a weakening trend. The detection of fixed sample plots of forest communities in protected areas is a long-term task, and the management of protected areas should be strengthened to strictly prevent the destruction of resources in protected areas by social idle personnel, so as to lay the necessary foundation for long-term ecological monitoring.更多还原
