摘　　要：采用2001年和2013年二类调查数据,统计吉林省柳河县8个国有林场和15个乡(镇)林业工作站12年间林地地类面积变化。通过分析,全县12年间林地面积增加2731.1hm 2,主要是退耕退林和有争议林地回收管理力度加大;同时增加了未成林地、无立林地、宜林地、辅助生产林地等面积。This paper uses the second-category survey data in 2001 and 2013 to count the changes in the forest land area type in 8 state-owned forest farms and 15 township(town)forestry workstations in Liuhe County of Jilin Province during 12 years.Through analysis,the county's forest land area increased by 2731.1hm 2 in the past 12 years,mainly due to the increased management of returning farmland and forests and controversial forest land recovery;at the same time,the area of uncultivated forest land,non-established forest land,suitable forest land,and auxiliary production forest land has been increased.
