摘　　要：绵竹是四川优良的乡土竹种。本研究在绵竹主要分布区沐川、叙永设置了125个经营水平大体一致的样地开展不同林分结构(年龄结构、均匀度、整齐度和立竹度)对绵竹产量的影响研究。结果表明:绵竹林的年龄结构、整齐度和立竹度对竹材产量有显著影响,而均匀度对产量影响不显著。当绵竹林以1 a^2 a年生竹为主,整齐度为10,立竹度在10 000株·hm^(-2)时,绵竹竹材产量最高,是绵竹林最优林分结构。Dendrocalamus farinosus is one of the native bamboos in Sichuan. In this study, the influence of bamboo age, even degree, uniform degree and density on bamboo yield were estimated by setting 125 sample plots which were managed in similar measures. The result showed that there were significant influence of age, uniform degree and density on bamboo yield, but the influence of the even degree was insignificant on the yield. As a consequence, it was found that the age structure（ 1 a -2 a prevailed）, 10 values uniform degree and 10000 plants per hectare were most optimized forest structure, able to obtain the highest yield.
