| 摘 要： | 对粗放经营的苦竹林林分结构与竹笋产出的关系进行了调查，利用SPSS软件构建了竹笋产量与立竹年龄结构的关系模型：Y=9192．375＋0．02027N＋0．12607D-0．11412X1＋0．24912X2＋0．33746X3-0．09919X4（R=0．94），提出了在粗放经营初期的优化年龄结构，立竹度7200～8100株／hm^2时竹笋产出高，1—4年生立竹比例为3：3：3：1。

| Abstract: | Through the investigation on the relationship between stand structure and shoot yield of extensively managed Pleioblastus amarus forest converted from natural stand, the model of relationship between shoot yield and age structure was established. Y=9 192.375＋ 0.02 027 N＋ 0.12 607D-0.11 412X1＋ 0.24 912X2＋ 0.33 746X3- 0.09 919X4 （R=0.94）, thus providing the method to optimize structure of Pleioblastus amarus forest at the initial stage of extensive management. The shoot yield is the highest when the culm density is 7 200-8 100 per ha. The ratio of 1-4 years old bamboo was 3：3：3：1. |
