摘　　要：分析了荞麦芦丁含量与气象因子的关系,结合荞麦地理分布信息,筛选出影响芦丁含量的主要气象因子,利用Arc GIS软件的空间分析功能,对荞麦芦丁含量进行生态区划,并进行评述。结果表明,品种和生态区域对芦丁含量具有明显的影响,而温度、降水、日照时数是影响芦丁含量的主要生态因子。芦丁含量与8月上旬均温、7月大于30℃天数具有负相关性,与8月降水量、生育期日照时数具有正相关性。利用GIS对芦丁含量进行区划,将晋中市分为3个区,即高、中、低芦丁含量荞麦种植区,与实际状况基本符合。研究结果可为高芦丁含量荞麦生产基地的确定和区域化、规模化种植提供参考。In this study,the correlation of buckwheat rutin content and meteorological factors were analyzed and combining with the geographical distribution information the major meteorological factors influencing rutin content were screened.The ecological zonation was evaluated using the ArcGIS spatial analysis technique.The results showed that the effect of varieties and ecological factors on rutin content was obvious,and temperature,rainfall and sunshine hours were the main ecological factors.The rutin content had positive correlation with rain fall in August and growing period sunshine hours and had the negative correlation with the mean temperature of middle ten days in August and the days of T 30 ℃ in July.Jinzhong city was divided into high,mid and low rutin content three planting zones using GIS,and the zonation was largely in line with the actual condition.The results could provide a reference for determining bases and regionalization,large-scale planting the high rutin content of buckwheat in Shanxi.
