摘　　要：目的建立山西省酸枣的分布区划,助力山西省酸枣产业的发展。方法基于山西省第四次全国中药资源普查所获酸枣样点经纬度等信息和中药资源空间信息网格数据库环境因子数据,利用地理信息系统软件ArcGIS和最大熵(MaxEnt)模型筛选出影响山西省酸枣分布的主要环境因子并进行分析。结果影响酸枣分布的主导环境因子为植被类型、最冷月最低温、11月份降水量、10月份降水量、海拔、坡度。从ArcGIS重分类的适生度栅格数据得出酸枣在山西省的高适生区面积约为0.73×10^(4) km^(2),中适生区面积约为1.41×10^(4) km^(2),低适生区面积约为4.33×10^(4) km^(2),同时发现酸枣中、高适生区主要分布在山西省中南部。结论本研究得出酸枣最适生长区主要位于山西省中南部,可为山西省酸枣资源开发利用和规范化种植提供参考依据。Objective To establish the distribution zoning of Ziziphus jujuba var.spinosa in Shanxi Province;To help the development of Z.jujuba var.spinosa industry in Shanxi Province.Methods Combined with the information of longitude and latitude of sample points from the forth national survey resources and environment factors data in Grid Database of Spatial Information of TCM Resources,the MaxEnt model and ArcGIS were applied to analyze the main environmental factors affecting the suitability distribution of Z.jujuba var.spinosa.Results Dominant ecological factors for the suitability distribution of Z.Jujuba var.spinosa were vegetation type,lowest temperature of coldest month,monthly precipitation in November,monthly precipitation in October,altitude,and slope.The reclassified suitability grid data of ArcGIS software showed that Z.jujuba var.spinosa suitability distribution area including 0.73×10^(4) km^(2) of high suitability area,1.41×10^(4) km^(2) of medium suitability area and 4.33×10^(4) km^(2) of low suitability area.The potential suitable distribution areas of Z.jujuba var.spinosa were mainly concentrated in the central and southern Shanxi Province.Conclusion This study shows that the most suitable growth area of Z.jujuba var.spinosa is mainly located in central and southern Shanxi Province,which can provide reference for the development,utilization and standardized planting of wild resources of Z.jujuba var.spinosa.
