摘 要:基于云南云龙天池国家级自然保护区2019年森林资源监测数据及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,保护区林地资源丰富,占比高达97.17%,林地分布均匀,且利用率较高;有林地占绝对优势,森林覆盖率高达92.25%;森林以天然林为主,面积占比达91%以上,优势树种主要为云南松和栎类,其中天池片区云南松林面积占比高达73.30%;活立木蓄积量较大,公顷蓄积量高达300 m3/hm2,天池片区林木公顷蓄积明显大于龙马山片区;天池片区林地生产力正处于顶峰阶段,近熟林和成熟林比重过大,林地生产力趋于减缓,龙马山片区林地生产力正处于旺盛阶段,具较大发展空间。Based on the monitoring data of forest resources in Yunlong Tianchi National Nature Reserve in 2019 and GIS technology,the current situation of forest resources in this area was analyzed and evaluated.The results showed that the forest land resources were rich in the reserve,accounting for 97.17%,which were evenly distributed with high utilization rate;the closed forest land was absolutely dominant,with the forest coverage rate as high as 92.25%;the forest was dominated by natural forest,accounting for more than 91%of the total area,and the dominant tree species were Pinus yunnanensis forest and Quercus forest,and the area of Pinus yunnanensis forest in Tianchi area accounted for 73.30%;the volume of standing trees was as high as 300 m3/hm2,and the volume per hectare in Tianchi area was larger than that in Longma Mountain area;the productivity of forest land in Tianchi area was at the peak stage,the proportion of near mature forest and mature forest was too large,and the productivity of forest land tended to slow down,while the productivity of forest land in Longma Mountain area was at the vigorous stage with the large development space.
