摘　　要：对北京地区园林中常见栽培的金镶玉竹和早园竹,选择不同地块对竹林结构进行了调查研究。结果表明金镶玉竹和早园竹林的存在立竹密度大、竹株胸径小、竹林内老龄竹比例大、竹林土壤中有效磷匮乏等问题。调查地块的大部分竹株胸径2 cm左右,只有参照组能达到参考丰产竹林标准3.5 cm;立竹密度大于80 000株/hm2,是丰产竹林的4-12倍;竹龄结构不合理,老龄竹占竹林的1/5-4/5,一二年生竹占竹林比例不足1/2,最少的只占竹林的8%。需要有计划地进行结构调整,提高竹林质量和景观。The grove structure of phyllostachys aureosulcata f. spectabilis and Ph. propinqua were studied at different sites in Beijing. The results indicated that their density was too high,the DBH of most bamboo shoots was too small,the high ratio of old bamboos was too high,and the effective phosphorus in the soil was too low. The DBH of bamboo shoots at most sites were about 2cm,and reached the high yield standard 3. 5cm only at the reference site. The density was higher than 80000 shoots per hm2,4-12 times of the commercial cultivation density. Old bamboo accounted for 1 /5-4 /5 of the bamboo populations and the share of young bamboo shoots was less than 1 /2. Therefore,it is urgent to adjust the bamboo grove structure in a planned way so as to improve the forest quality and landscapes.
