摘要(Abstract)：

本文采用贡嘎山竹类调查分布位点和World Clim生物气候数据,利用集合模型构建了贡嘎山区3种竹类的分布预测。模型结果反映出了竹类分布的地域和生境特征,丰实箭竹和冷箭竹主要分布在贡嘎山东部地区,而峨热竹主要分布在东南部和西北部地区。丰实箭竹的分布海拔最低,而冷箭竹的最高,但是在分布面积上则以峨热竹最多,冷箭竹最少。粗分辨率的气候数据导致分布预测的海拔范围出现较大偏差;将研究区域细分成相对均匀的小块做模型分析,能够更加准确地预测物种的分布。本研究结果可作为保护区区划规划和生物多样性保护工作的依据。
Ensemble modeling of Biomod2 package was used to predict the distribution of three bamboo species in the Gongga Mountains with the survey data of occurrence locations and bioclimate dataset of WorldClim. The results reflected a clear pattern in distribution and habitat preference. Fargesia ferax and Bashania fangiana grew in the east part of the Gongga Mountains while Bashania spanostachya in the west and southeast. Bashania spanostachya was sandwiched between the higher Bashania fangiana and lower Fargesia ferax in elevational distribution,but stretched more extensively than the latter two species. Bashania fangiana was distributed to the upper part of eastern valleys and forms a much narrow belt. This research would be helpful for the biodiversity conservation and regional planning of the reserve.
