摘　　要：从农业生产的角度，在西北半干旱区县级区域尺度上，运用GIS技术，选取区域差异明显、时间序列上相对稳定特征的对甜菜生长影响较大10个因子，建立评价指标体系，h划分适宜性区域。结果表明：研究区甜菜种植高度适宜面积39261．8hm2，占总面积的29．15％，适宜面积79721．4hm2，占总面积的59．18％，勉强适宜面积15723．38hm2，占耕地总面积的11．67％；半干旱区总体上都适宜种植甜菜。In this study, 10 factors influencing the growth of sugar beet with obvious regional differences and relatively stable characteristics in time series were selected by using GIS technology. Those 10 factors were used to establish the evaluation index system which could classify suitable regions for beet planting in northwest China. The results showed that the area which were very suitable for beet planting in the study area was 39 261.8 hm2, accounting for 29. 15% of the total area; the area which were suitable for beet planting in the study area was 79 721.4 hm2, accounting for 59. 18% of the total area; and the area which were barely suitable for beet planting was 15 723.38 hm2, accounting for 11.67% of the total area. In general, semi -arid regions is suitable for sugar beet planting.
