摘　　要：对福建省建瓯市野生福建酸竹低效林实施松土、施肥等低效改造抚育措施,比较分析改造前后竹林立竹密度、地径、林龄结构及笋产量的变化情况,结果表明:与对照区相比,2007年改造区竹林立竹密度增加5021株.km-2,平均地径提高0.3 cm,Ⅰ-Ⅲ度竹所占比例提高42%,产笋量增加433 kg.km-2,经济效益明显,低效改造基本成功。The transformation and cultivation measures such as turning soil, fertilization were conducted in the wild low yield Acidosasa notata forest in Jian＇ou, Fujian, the change in density, ground diameter, forest ages and shoot yields before and after transformarion was compared and analyzed. The results showed that, compared to the control, the density was increased by 5021 trees per square kilometers, average ground diameter was increased by 0.3 cm, percentage of the first to third grades bamboo was increased by 42%, and shoots yield was increased by 433 kg · km-2 in the transformed forest, 2007. The significant economic effect has proved the success of transformation of the low yield A. notata forest.
