以赤峰市城子乡为例，在GIS技术的支持下，借助DEM图提取高程、坡度信息，分别与2001年和2011年的土地利用空间格局分布图进行空间叠加，系统分析研究区近10 a土地利用空间格局的分布与变化的地形梯度特征，探讨地形因素对土地利用方式选择及空间格局的影响。结果表明：( a)地形因素对土地利用空间格局在垂直方向上具有控制性作用，表现为随着高程的增加，林地变为主要利用类型，耕地在各高程区域中的相对数量呈现先增加后减少的趋势，城镇村及工矿用地、交通运输用地和水域及水利设施用地的分布比例逐渐减少，同时土地利用多样性降低。与人类生产生活密切相关的土地利用类型大多分布在0o~3o坡度段内，城镇村及工矿用地主要分布在<8o坡度段内，说明其受地形地貌因素影响较大，对坡度选择性较高。( b)地形因素对研究区不同土地利用类型的转化有显著影响，不同地形区域土地利用类型的转化存在一定差异，低地形区域是土地利用空间格局变化最为活跃的区域。说明土地利用空间格局是自然条件限制和人类活动影响共同作用的结果，地形是形成土地利用空间格局的背景性基础因素。

Taking Chengzi Township in Chifeng City as an example, with the support of GIS technology, we extracted elevation and slope information using DEM maps and conducted spatial overlay analysis with the spatial pattern maps of land use in the years 2001 and 2011 , in order to systematically analyze the terrain gradient features of the spatial pattern distribution and changes of land use in the study area over the last ten years, and to explore the impacts of terrain factors on the selection of land use modes and the spatial patterns of land use. The study results are as follows: ( a ) Terrain factors play a dominant role in the spatial pattern of land use in the vertical direction. With an increase of the elevation, the woodland changes into the main land use type, the relative area of cultivated land in various elevation ranges increases initially, and then decreases, and the proportions of urban village, industrial and mining lands, traffic and transportation lands, water areas, and water conservancy facilities lands decrease gradually. Meanwhile, the diversity of land use diminishes. The land use type that is closely associated with human society ’ s production activities and living is mostly distributed over 0o to 3o slopes, and urban village and industrial and mining lands are mainly distributed over slopes of below 8o, indicating that they are greatly influenced by terrain factors and have high selectivity of slopes. ( b ) Terrain factors have a significant impact on the conversion of different land use types in the study area. There are certain differences in the conversion of land use types in different terrain areas. Low-terrain areas are the areas where the spatial pattern of land use changes most significantly, indicating that the spatial pattern of land use is affected by the joint action of natural conditions and human activities, and terrain is the background factor in the formation of the spatial patterns of land use.
