摘　　要：为评价我国东北东部山区脂松(Pinus resinosa)的引种效果,探究脂松在各引种栽培区的生长适应性,以3个不同试验区(帽儿山、露水河、湾甸子)19年生的脂松人工林为研究对象,通过外业调查和树干解析获取生长数据,分析树高、胸径和材积生长过程。结果表明:引种到东北东部山区3个试验区的脂松均能正常生长,而且生长规律基本一致;胸径随着年龄的增大呈S型曲线增长,树高和材积生长整体呈J型曲线增长;5年生脂松树高生长速率为0.17~0.20 m/a,树高从生长第6年开始进入速生期,6~19年生脂松的树高生长速率达0.53~0.66 m/a;脂松胸径起始连年生长量小,之后随着林龄的增加胸径快速增大,林龄达到17 a时,脂松胸径生长开始缓慢下降;林龄1~6 a的脂松材积增长缓慢,且各试验区相差不大,随着林龄的增加迅速增长,露水河脂松材积生长优势逐渐明显。露水河试验区19年生脂松平均树高、胸径和材积表现最好。因此,引种至我国东北东部山区的脂松生长适应性良好,连年生长量大,生长速率快,可以作为优良常绿针叶树种栽培。To evaluate the introduction effect of Pinus resinosa in the eastern mountainous areas of Northeast China,and explore the growth adaptability of P.resinosa in different introduction cultivation areas,a study was conducted on 19 yearold artificial forests of P.resinosa in three different experimental areas(Maoershan,Lushuihe,and Wandianzi).Growth data were obtained through field surveys and trunk analysis,and the growth processes of tree height,diameter at breast height(DBH),and volume were analyzed.The results showed that P.resinosa introduced to the three experimental areas in the eastern mountainous areas of Northeast China could grow normally,and the growth patterns were basically consistent.The DBH showed an S-shaped curve growth with increasing age,while the tree height and volume showed a J-shaped curve growth overall.The growth rate of tree height for 5 yearold P.resinosa was 0.17-0.20 m/a,and it entered the rapid growth period from the 6 th year onwards,with a growth rate of 0.53-0.66 m/a for 6-19 year old P.resinosa.The initial annual growth of DBH of P.resinosa was small,and then it rapidly increased with the increase of stand age.When the stand age reached 17 years,the growthof DBH started to slow down decreased slowly.The volume growth of P.resinosa was slow for 1-6 year old stands,and there was not much difference among the experimental areas.However,it increased rapidly with the increase of stand age,and the growth advantage of P.resinosa volume in Lushuihe gradually obvious.The average tree height,DBH,and volume of 19 yearold P.resinosa in Lushuihe experimental area performed the best.Therefore,P.resinosa introduced to the eastern mountainous areas of Northeast China has good growth adaptability,large annual growth,and fast growth rate,and can be cultivated as an excellent evergreen coniferous tree species.
