摘　　要：本文根据对会东县双低油菜种植有决定意义的农业气象指标,采用会东县气象局所辖国家气象站及区域气象站资料为基本资料,通过数理统计方法分别建立各指标要素的空间分布模型,利用1∶50 000地理信息资料将各指标要素按500 m×500 m分辨率展开,再利用GIS技术,以乡镇为单位,制作多层次平面区划图,根据区划指标将会东县双低油菜种植区划分为适宜区、次适宜区和不适宜区。其中,适宜区主要集中在小坝乡、姜州镇、铁柳镇、鲹鱼河镇、嘎吉镇、乌东德镇、堵格镇的大部分区域及其余乡镇海拔较低区,次适宜区主要集中在堵格镇、拉马乡、野租乡、淌塘镇、老君滩乡、满银沟镇和铅锌镇,不适宜区主要集中铅锌镇、鲁吉镇、溜姑乡和松坪镇局部区域。According to the agro-meteorological index which determines double-low rapeseed planted in Huidong County,using the data from national and regional weather stations as basic information,the spatial distribution models of each index element were developed with mathematical statistics methods. Expanding each index element in resolution of 500 m×500 m by using 1∶50 000 geographic information data,a multilevel plane zoning map was made. According to the division indexes,based on GIS technology,the double-low rapeseed-growing region in Huidong County in all townships was divided into the suitable areas,the sub-suitable areas and the unsuitable areas.Among them,the suitable areas mainly concentrated in Xiaoba Township,Jiangzhou Town,Tieliu Town,Shenyuhe Town,Gaji Town,Wudongde Town,most area of Duge Town and other township lower altitude area;the sub-suitable areas mainly concentrated in Duge Town,Lama Township,Yezu Township,Tongtang Town,Laojuntan Township,Manyingou Town and Qianxin Town;the unsuitable area mainly concentrated in Qianxin Town,Luji Town,Liugu Township and part of Songping Town.
