| 摘 要： | 依据2000年甘肃省土地利用数据,运用地理信息系统空间分析方法以及最小方差法,在全面分析了甘肃省81个县(市)土地利用结构类型的基础上,对甘肃省土地利用进行了分区研究,结果表明：全省可划分为陇东黄土高原、陇中黄土丘陵、陇南山地、甘南高原和河西走廊5大土地利用区,这不仅揭示了甘肃省土地利用的空间分异规律,而且也为全省的农业区划和规划以及土地资源的可持续利用提供了科学依据。

| Abstract: | Some forerunners have studied the regionalization of land use in Gansu Province which was based on the qualitative analysis. This paper discusses the regionalization of land use in this Province from a new point of view. By means of GIS technology and Least Square Error, we provide a quantitative method to study the problem. According to the classification of land use structure types, we compare the result with the regionalization mentioned in Study on comprehension development and planning of land use in Gansu Province. The research has shown the means of Least Square Error is reasonable and scientific.;At the end, we discuss the result of regionalization. Gansu Province can be divided into five regions of land use: Long-dong Loess Plateau, Long-zhong Loess Hills, Long-nan Mountains, Gan-nan Mountains and He-xi Corridor. |
