摘　　要：在思茅松适生的临沧市临翔区,通过调查428株思茅松采脂木的树高、胸径及材积等生长量,并对未采脂的45株思茅松进行树干解析,建立其树高、胸径与材积标准生长曲线,对比分析了思茅松采脂后树高、胸径、材积等生长量降低比例,研究了采脂对思茅松林木生长的影响。研究结果表明,(1)采脂使思茅松林木生长放缓,对各径阶林木生长皆有不同程度的影响,其中,采脂对思茅松材积生长影响最大,其材积降低24.84%,其次是胸径,采脂后胸径生长降低17.12%,对树高生长影响较小。(2)林木径阶越小,林木受采脂影响越大,各指标生长降低比例越大。建议规范采脂,降低对思茅松林木生长的影响。To understand the impact of resin tapping on tree growth of Pinus kesiya var. langbianensis, a survey ontrees＇ height, diameter at breast height （DBH） and volume of 428 trees with resin tapping were conducted in theLinxiang district of Lincang city. After sem analysis, and establishing standard curves of tree height, DBH andtree volume of 45 trees without tapping, a comparative analysis on corresponding indicators before and after resintapping were made. The results showed that ： （ 1 ） resin tapping make Pinus kesiya vat. langbianensis grow slower,and this affects tree growth of each diameter grade. Its effect on volume growth is the greatest with a reduction of24. 84 %, following by the DBH with a reduction of 17.12 %, and less effect on tree height growth; （2） thesmaller of diameter grade while resin tapping, the greater reduction of trees growth and relevant growth indica-tors. To reduce its negative effects on tree growth of Pinus kesiya var. langbianensis, resin tapping with some regula-tions should be adopted in practice.
