摘　　要：为研究西昌市印度黄檀人工林生长规律,对西昌地区8 a生印度黄檀人工林进行调查,选取标准木进行了树干解析,通过绘制树高、胸径、材积生长和胸高形数的生长曲线图,分析探讨了该地区印度黄檀的动态生长规律。结果表明,西昌地区8 a生印度黄檀树高、胸径、材积生长分别可达12.20 m、18.50 cm、0.12690 m^(3),其树高、胸径和材积生长曲线均呈“S”形变化的趋势,均表现出最初生长阶段值较小,但生长速率较快的特点。树高和胸径的年平均生长量、连年生长量均分别在第5年、第4年达到最大值后逐渐下降。材积生长的年平均生长量和连年生长量曲线未交叉,均处于持续增长期,表明8a生印度黄檀材积生长还具有较大增长空间。To analyze the growth law of Dalbergia sissoo in Xichang City,the 8-year-old Dalbergia sissoo plantation in Xichang was investigated,the tree trunk was analyzed by selecting standard trees,and the growth curves of tree height,diameter at breast height,volume growth and shape number at breast height were drawn to analyzes and discusses the dynamic growth law of Dalbergia sissoo in this area.The results showed that the height,DBH and volume of 8-year-old Dalbergia sissoo in Xichang grew up to 12.20 m,18.50 cm and 0.12690 m^(3) respectively,and showed an"S"shape change trend,which reflect the characteristics of smaller value in the initial growth stage but faster growth rate.The average and current annual increment of height and DBH respectively reached the maximum value in the 5th and 4th year,and then gradually decreased.The average and current annual increment growth curves of volume didn't cross,both was in the period of continuous growth,indicated that there was still a large space for growth of volume of 8-year-old Dalbergia sissoo.
