小蓬竹具有较高的经济、社会和生态价值，且为濒危竹种，但繁殖成活率很低，引种栽培长势也较原生境差。为探索上述原由，在野外样地调查的基础上，利用SPSS软件进行相关性分析，研究小蓬竹在不同生境条件下的生长状况，为小蓬竹的经营、利用和保护提供科学依据，结果表明：①小蓬竹生长受坡向影响很大；②坡位对小蓬竹生长的影响并不大；③小蓬竹在不同坡度均能够生长，坡度30°以下较利于小蓬竹生长；④海拔对小蓬竹的生长有很大的影响。
小蓬竹具有較高的經濟、社會和生態價值，且為瀕危竹種，但繁殖成活率很低，引種栽培長勢也較原生境差。為探索上述原由，在野外樣地調查的基礎上，利用SPSS軟件進行相關性分析，研究小蓬竹在不同生境條件下的生長狀況，為小蓬竹的經營、利用和保護提供科學依據，結果錶明：①小蓬竹生長受坡嚮影響很大；②坡位對小蓬竹生長的影響併不大；③小蓬竹在不同坡度均能夠生長，坡度30°以下較利于小蓬竹生長；④海拔對小蓬竹的生長有很大的影響。

Drepanostachyum luodianense has high economic,social and ecological value,which is endanger bamboo species,but the propagation survival rate was very low and introduction cultivation growth vigor were much more poorer than the original habitats. In this paper,to explore the reasons of the above circumstances, based on field comprehensive investigation and using of SPSS software for correlation analysis,to study on the growth of D.luodianense in different habitats,in order to provide a scientific basis of D.luodianense for the management,utilization and protection. The results showed that:①D.luodianense growth was highly effected by the slope direction;②Effection of Slope position to the growth of D.luodianense was not obvious;③D.luodianense could grow on different slope,slope below 30°was more beneficial to D.luodianense growth;④Elevation had a great influence on the growth of D.luodianense.
