摘　　要：应用1971～2000年气象资料和1∶25万地理信息数据资料,在Citystar平台上,制作张掖甘蓝型油菜农业气候区划,数据图层准确性较好,据统计与实际资料的相对误差在10%以下;张掖甘蓝型油菜种植可划分为4个区,即最适宜区、适宜区、次适宜区和不适宜区,为当地农业结构调整和基地建设提供了科学依据,并使得农业气候区划数字化、立体化成为可能。Based on meteorological data (1971~2000) and geographical information data (1∶250000), the climate division of cabbage rape was conducted in Zhangye by using the platform of Citystar. It was proved that the data layers were fairly accurate, and the relative error was less than 10% compared to the actuality. The results showed the possibility of digital and solid agricultural climate division and might provide scientific basis for local agricultural production.
