运用地形分布指数、地形位指数将贵州省六盘水市“玉—马”经济带2012年、2018年的土地利用数据在不同地形位的分析研究。结果表明：耕地、公共管理与服务用地、水域设施用地、园地、工矿仓储用地、住宅用地在低地形位上优势明显，林地、草地、灌木集中分布在中、高地形位上；在研究期间内，耕地、草地在高地形位上面积减少，中高地形位上灌木的优势区增加，工矿仓储用地和其他用地集中到了低地形位和中高地形位，设施农用地由中地形位向低地形位转移，其余土地利用类型的优势区分布变化不明显；人类活动对土地利用变化的影响较大，地形位对土地利用变化的影响不明显。研究可为我国西南喀斯特山区地形地势对小型经济区的发展提供验证解读。

We used topographic distribution index and topographic position index to analyze and study the land-use data of“Yu-Ma”economic belt in Liupanshui City, Guizhou Province in 2012 and 2018 at different topographic positions. The results show that cultivated land, public management and service land, water facility land, garden land, industrial and mining storage land and residential land have obvious advantages in the low topographic position, while woodland, grassland and shrub concentrate in the middle and high topographic position. During the study period,the area of cultivated land and grassland decreased at the high topographic position, the dominant area of shrub increased at the middle and high topographic position, the industrial and mining storage land and other land concentrated at the low and middle topographic position, the facility agricultural land shifted from the middle topographic position to low topographic position, and the distribution of the dominant area of other land-use types did not change significantly. Human activities have a great influence on land-use change, but topography has no obvious influence on land-use change. The research can provide the verification and interpretation for the development of small economic zone of Karst mountain terrain in southwest China.
