摘要：在草地综合顺序分类系统（IOCSG）的指导下，以甘肃省 113 个气象站点多年 0年
积温（Σθ）和年降水量（r）以及 DEM 数据为主要数据源，采用“多元回归+残差分析法
（AMMRR）”进行气象数据空间化，通过空间叠置分析完成甘肃省草地类的划分。研究结果
表明：甘肃省共有 28 个 IOCSG 草地类，面积最广的有 4 个，分别是微温极干温带荒漠类（
A3）、微温干旱温带半荒漠类（B10）、微温湿润落叶阔叶林类（E31）和寒冷潮湿高山
草甸类（F36），分别主要分布在北山山地、河西走廊、黄土高原和甘南高原；亚热带的
几个类（B12、C19、D26 和E33）分布面积较小，比例不足 1%。研究结果符合甘肃
省各区域的气候特点。AMMRR 法充分考虑了地形因子（经度、纬度和海拔高度）对气象要素
的影响，使Σθ和 r 插值结果更接近实际，得到的草地分类图也充分体现出了植被的地带性
规律，模拟效果较好。
