  • Pleioblastus maculatus is one of the most excellent shoot-used bamboos in south Sichuan. 3 stand factors(age structure, DBH structure and bamboo density) were chosen to analyze the influence on bamboo shoots. The results showed that there were significant influence between 3 stand factors and bamboo shoots, and no significant influence were found between DBH uniformity and bamboo shoots. One year, two years and three years old dominant stands were found to be the better age structure with a highest shoot yield (4 770 kg·hm-2) and shooting number(13 900 hm2); 6cm DBH stand was found to be the better DBH structure with a highest shoot yield(4 550 hm2); 10 000~12 000 hm2 were found to be the better stand density with a highest shoot yield(4 700 kg·hm-2) and shooting number(15 500 numbers·hm-2).In conclusion, the ideal stand structure was found to be composed of dominant age of 1 year+2 year+3 year, DBH of 4~6cm, and medium stand density(10 000~12 000 numbers·hm-2).
