为小蓬竹引种栽培提供指导依据，通过样方法对贵州罗甸、平塘3块不同样地小蓬竹群落中各物种的重要值、生态位宽度、生态位相似性比例进行研究。结果表明，群落中小蓬竹的重要值最高，为792；生态位宽度值最大，为2．8904；小蓬竹与群落内榆树、女贞、云实、黄连木和椤木石楠的生态位相似性比例较高，分别为0．61、0．66、0．68、0．71和0．69。结论：小蓬竹在群落中的适应能力及利用资源的能力最强，但当环境资源不足时，小蓬竹与群落内生态位相似性比例较高的植物之间存在激烈竞争，小蓬竹的建群种地位会受到威胁，因此，引种时应避免与榆树、女贞、云实、黄连木、椤木石楠一起栽培。

In order to provide some guidance for introduction and cultivation of D.luodianense,the important values,niche breadth,niche proportional of main species were studied with three different samples in Luodian and Pingtang of Guizhou with sampling methods.Results:the important value of D.luodianense was 792 and niche breadth of was 2.8904;the important value and niche breadth were the highest, niche proportional similarity of D.luodianense was similar to Ulmus pumila, Photinia davidsoniae, Caesalpinia decapetala, Ligustrum lueidum and Pistacia chinensis. The values were respectively 0.61,0.66,0.68,0.71 and 0.69.Conclusion:the adaptive capacity of D.luodianense in the community and the use of resource were the strongest.While intense competitions were observed between D.luodianense and plants with higher proportion of niche similarity when the environmental resource was deficient. And the edificator status would be threatened. Consequently, it was essential to avoid introducing and cultivating Ulmus pumila, Photinia davidsoniae, Caesalpinia decapetala, Ligustrum lueidum and Pistacia chinensis in D.luodianense community.
