Abstract:
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 0.73×104 km2 of high suitability area,1.41×104 km2 of medium suitability area and 4.33×104 km2 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.
