[目的]基于气候和土地利用信息,对贵州黔西南地区特色优势中药材艾纳香种植适宜性类型分布区域进行科学划分,为黔西南地区艾纳香种植产业规划和可持续发展提供参考依据.[方法]在艾纳香成功种植经验的基础上,确定5个关键气候因子作为艾纳香种植适宜性类型分布等级指标,并且建立了关键气候因子与潜在种植分布区域海拔高度的回归模型.运用GIS技术,提取黔西南地区艾纳香种植适宜性类型分布的区域,通过与可利用的土地类型信息叠加,得到黔西南地区艾纳香种植适宜性类型的具体分布情况.[结果]黔西南地区艾纳香的种植适宜性类型主要分布在海拔747m以下区域,最适宜种植区面积共计8310hm2,适宜种植区面积共计5864hm2,次适宜种植区面积共计3738hm2.[结论]研究结果客观地反映了黔西南地区艾纳香种植适宜性类型的区域面积及地理分布情况,对未来该地区艾纳香种植产业的科学发展与精准决策具有重要的参考和指导意义.%Based on the climate and land used information, this paper scientifically divided the regional distribu-tion of suitable varieties of B.balsamifera-planting in the southwest Guizhou province,and provided reference for the planning and sustainable development of cultivating B.balsamifera.On the basis of the experience of cultiva-ting B.balsamifera successfully,five key climatic factors were identified as the distribution index of the suitability type,and the regression model of the critical climatic factors and the altitude of the potential planting area was es -tablished.Using GIS technology,the area of suitable type distribution of B.balsamifera cultivation in southwestern Guizhou province was extracted,and this was obtained by superimposing with available information about the land type.The results showed that the suitable types of cultivation in the southwest of Guizhou were mainly distributed in the area of 747m or less,and the optimum area was 8 310 hm2,the suitable area was 5 864 hm2,and then 3 738 hm2.The results of the study objectively reflect the regional area and geographical distribution of the suitability types of B.balsamifera in the southwest of Guizhou province,which is a great reference for the future scientific de-velopment and an important guidance for the precise decision making in this specific area.
