基于MaxEnt模型和ArcGIS的山西远志适生区预测研究OACSTPCD
Prediction Study on Suitable Growth Areas of Polygala tenuifolia in Shanxi Province Based on MaxEnt Model and ArcGIS
目的 预测远志在山西的潜在适生区分布,为远志现有资源的发掘利用及栽培区域的选择提供依据.方法 收集1 102个远志样点(其中远志1 060个、卵叶远志42个)分布信息,结合55个环境因子数据,应用最大熵(MaxEnt)模型和地理信息系统软件ArcGIS分析影响远志适生区分布的主要环境因子.结果 影响远志适生区分布的主要环境因子有植被类型、降水量、温度等.远志在山西省潜在适生区分布主要集中于临汾、吕梁、太原、长治、晋中、运城东南部、忻州西北部、朔州西南部等地.结论 本研究预测的远志和卵叶远志生态适宜性区划可为山西远志种植地区的选择和药材规范化生产提供参考.
Objective To predict the potential suitable distribution areas of Polygala tenuifolia in Shanxi Province;To provide basis for the excavation and utilization of existing resources and the selection of cultivation areas of Polygala tenuifolia.Methods The distribution information of 1 102 Polygona tenuifolia samples was collected(Among them,there were 1 060 samples of Polygala tenuifolia Willd.,42 samples of Polygala sibirica L.).Combined with the 55 ecological factor data,the MaxEnt model and ArcGIS were applied to analyze the main ecological factors affecting the distribution of Polygala tenuifolia.Results The dominant ecological factors for the suitability distribution of Polygala tenuifolia were vegetation type,precipitation,temperature,etc.The potential suitable distribution areas of Polygala tenuifolia in Shanxi Province were mainly concentrated in Linfen,Lvliang,Taiyuan,Changzhi,Jinzhong,southeastern of Yuncheng,northwestern of Xinzhou,southwestern of Shuozhou,etc.Conclusion The ecological suitability zoning map of Polygala tenuifolia Willd.and Polygala sibirica L.was obtained,which can provide reference for the reasonable selection of planting areas and standardized production of Polygala tenuifolia in Shanxi Province.
