摘　　要：基于云南省“十三五”期间各年度森林资源调查、监测数据,采用比较分析法,对云南省及滇中、滇西、滇西北、滇东北、滇东南、滇西南六大片区森林覆盖率动态变化进行分析。结果表明,云南省“十三五”期间森林覆盖率年均增长1.44个百分点,呈快速增长趋势。从时间上看,2020年增长最为迅速,2017年增长最缓慢;从区域上看,滇东北、滇东南等少林地区森林覆盖率增长迅速,滇西、滇西北、滇西南等多林地区森林覆盖率增长缓慢;从变化原因上看,人工造林更新措施是云南省森林面积增加、森林覆盖率增长的主要原因。Based on the annual forest resources investigation and monitoring data during the 13th Five-Year Plan period,the dynamic changes of forest coverage in Yunnan Province and the six regions of central,west,northwest,northeast,southeast and southwest Yunnan were analyzed by using the comparative analysis method.The results showed that the average annual growth rate of forest coverage was 1.44 percentage points,showing a rapid growth trend.In terms of time,the growth was the fastest in 2020 and the slowest in 2017;in terms of regions,the forest coverage in northeast and southeast Yunnan increased rapidly,but increased slowly in the west,northwest and southwest Yunnan;in terms of change reasons,artificial afforestation and renewal was the main reasons for the increase of forest area and forest coverage.
