摘　　要：以国家退耕还林政策的实施为背景，结合三峡库区护岸林建设，通过对栽植于重庆涪陵南沱镇连丰村的笋用竹撑绿杂交竹3号护岸林的调查，测定了撑绿竹杂交3号在不同立地条件下的竹丛秆数、胸径、生长宽和竹高等生长因子，并分析了这些因子和立地条件的关系，采用F检验、SSR法多重比较，结果表明：坡向对竹高有极显著影响，阳坡竹子比阴坡竹子平均高1．30m；土壤厚度对生长宽和竹高有显著影响，在40～60cm厚的土层上竹子的生长宽比在20-40cm厚的土层上的竹子生长宽平均宽0．20m，竹高平均要高0．82m；不同立地因子组合对竹高有极显著影响，平均竹高变化范围在7．47～9．54m之间．With the implementation of the national policy of reforestation and the construction of bank protection forests in the Three-Gorges Reservoir, an investigation was carried out, in which the number, stem DBH, growth width and stem height of hybrid bamboo No： 3 （Bambusa pervaiabilis × Dendrocalamopsis oldhami） planted in different environmental conditions were measured. The interrelation between these factors and environmental conditions were analyzed by F test and Duncan＇s new multiple range method （SSR）. The orientation of the bank had a significant effect on stem height： the average stem height on the sunny bank was 1.30 m more that that on the shady bank. Soil layer depth had a significant influence on growth width and stem height, the average growth width and stem height of the bamboo growing in soil 40 -60 cm in depth were 0. 20 m and 0. 82 m greater than those growing in soil 20-40 cm in depth, respectively. Different site conditions highly significantly affected stem height, which varied from 7.47 to 9.54 m.
