摘　　要：目的探讨基于多元统计方法分析在地理信息系统技术支持下研究影响地榆在吉林省分布的各个生态因子,寻找吉林省地榆分布的主要的生态因子,建立吉林省地榆分布的Logistic模型,分析地榆在吉林省的资源分布情况。方法对地榆在吉林省各地区分布进行实地调查,利用GIS技术获取地榆在各个分布点的各项生态数据和各分布点的经纬度等信息。利用主成分分析确定吉林省地榆分布主要的正态因子;利用Logistic回归分析确定对地榆分布有显著影响的生态因子。结果吉林省地榆分布的生态因子主要有三个主成分,分别为代表降水量因子、温度因子和土壤因子。海拔、纬度、年均温变化范围、温度季节性变化标准差、最干季降水量、最干月降水量、年平均降水量、季节降水量变异系数是显著影响吉林省地区地榆品种分布的因素(P<0.05)。结论主成分分析和Logistic回归分析可以对吉林省的地榆资源分布的影响因素做出有效的分析。Objective To investigate the significant influential ecological factors of Sanguisorba officinalis in Jilin Province based on the muhivariate statistical analysis in support of GIS, analyse th main ecological factors , establish the Logistic mode[ of San- guisorba officinalis in Jilin Province. Methods Conduct field survey of Sanguisorba officinalis distribution in Jilin Province. Ac- cess the information of the latitude and longitude and various ecological data in each distribution point using GIS. Determine the major significant ecological factors of Sanguisorba officinalis distribution in Jilin Province using Logistic analysis. Results There are three major factors made up of linear coMbination of various precipitation factors, temperature factors and soil factors. Alti- tude, latitude, temperature range, temperature variation of seasonal precipitation in dt＂y season, the standard deviation, the dry monthly precipitation, mean annual precipitation and seasonal precipitation variation coefficient is significantly at]ected areas in Ji- fin Province factors Sanguisorba species distribution （P 〈 0.05 ）. Conclusion Principle component annlysis and logistic regression analysis can effectively analyse the significant influence factors of the distribution of Sanguisorba offieinalis resources in Jilin Prov- ince.
