摘　　要：通过调查分析吉林市林业局区划内不同地貌、坡向、坡度、坡位的地理环境下长白落叶松人工林的分布情况,对比不同土壤类型、土壤厚度下长白落叶松人工林生长状况,分析长白落叶松人工林不同龄组的面积、蓄积现存量等资源现状,对比相同龄组下不同林龄的长白落叶松小班个数占同龄组小班总个数的百分比,横向对比分析和纵向对比分析不同郁闭度等级的长白落叶松分布情况,为更好的经营管理人工落叶松林提供数据支撑。This article investigates and analyzes the distribution of Larix olgensis A.Henry plantations under different geographical environments such as landforms,slope orientations,slopes,and positions within the Jilin Forestry Bureau.It compares the growth status of Larix olgensis A.Henry plantations under different soil types and thicknesses,and analyzes the current resource status of Larix olgensis A.Henry plantations in different age groups,such as their area,storage,and standing stock.We compared the percentage of the number of small classes of Larix olgensis A.Henry in different forest ages under the same age group to the total number of small classes in the same age group,and conducted horizontal and vertical comparative analysis on different canopy closure levels to support the data.
