摘　　要：本文采集贵阳市花溪区3株构树,通过树干解析方法,研究其树木生长特性。结果表明:构树生长快,11年生时构树单株平均胸径总生长量已达17.35 cm、胸径连年生长量大,一般1.5 cm左右,树高总生长量13.43 m、材积总生长量0.1572m3,胸径速生期在5-7 a。The research objects were Broussonetia Ipyrifera （ L. ） Vent. in natural forests in Huaxi District of Guiyang , by measuring trunk analysis to study the analytical method of growth characteristics. The results indicated that was Broussonetia lpyrifera （ L. ） Vent fast - growing . 11 - year - old＇ s total diameter at breast height growth was 17.35 cm in diameter. Generally,diameter at breast heiht was about 1.5 cm, height growth was 13.43 m,and the total volume of timber growth was 0. 1572 m3. The fast - growing period for was diameter at breast height growth 5 - 7 years.
