红云红河卷烟原料K326的生态区划研究

摘要

为进一步探索云南省26个种植K326品种县（市）的生态区划，通过GPS定位系统及当地气象部门提供的30 a气象资料，收集了该种植区域的地理因子和气候因子信息，通过凝聚系统聚类中的组间连接聚类法，对K326品种种植区域的经度、纬度、海拔及大田期均温、降雨量和日照时间等进行聚类分析。结果表明，可将云南烟区划分为昆明、曲靖、红河、保山和昭通5个大生态区以及13个生态亚区。%In order to study the ecological regionalization of 26 counties in Yunnan tobacco-growing areas of the variety K326,through GPS system and the weather data of thirty years by the local weather bureau,we collected the climate and geography factors by the clus-ter analysis in cohesion system,and did the cluster analysis on the longitude,latitude,altitude and average temperature,average sun-shine,average precipitation in the field.The result shows that Yunnan tobacco-growing areas where flue-cured tobacco variety K326 is planted is divided into five major ecological zones and twelve ecological sub-regions.
