摘　　要：竹丛结构状况直接影响着竹子的生长环境。通过丛初植立竹数、立竹空间分布和丛立竹数等对小佛肚竹Bambusa ventricosa秆形变异的影响进行研究。结果表明：新竹畸形秆率随丛初植立竹数和栽植后年份的增加而降低，丛初植立竹数以2～3株为宜；出笋后的丛立竹数与竹丛外围、内围新竹数分别呈正相关和负相关，与新竹畸形率呈负相关；竹丛畸形秆新竹数随丛立竹数（出笋前）增加呈先升后降的趋势，丛立竹数与新竹畸形率呈负相关，人工栽培的丛立竹数应控制于4～6株。The clump structure affected the growing environment of bamboo directly. The relationships of initial culm number per clump, spatial distribution of culm and culm number per clump with the culm morphological variation of Bambusa ventricosa were studied. The results showed that abnormal rate of new culm decreased with increasing initial culm number per clump and time. The suitable culm number per clump was 2 -3. The number of new bamboo outer and inner clump was correlated negatively and positively respectively with culm number per clump after shooting. Abnormal rate of new culm was negatively correlated with culm number per clump after shooting. Abnormal number of new culm decreased with increasing of culm number per clump before shooting; abnormal number of new culm was negatively correlated with culm number per clump before shooting. The suitable number per clump should be 4 -6 in operation. [Ch, 1 fig. 2 tab. 10 ref.]
