摘　　要：耕地是石家庄市主要的土地利用类型,耕地与粮食密不可分,更与人类生产生活息息相关。基于石家庄市的DEM数据、坡度数据、地貌数据、地形起伏度数据、石家庄各市县行政区划数据,结合地理信息系统理论以及空间分析方法,借助ArcGIS软件,得到石家庄市各市县耕地适宜性结果。研究表明:石家庄市东部地区耕地适宜性等级较高,西部和北部地区适宜性等级比较低。石家庄市耕地适宜性等级为高度适宜的区域面积最大,为7705.96 km2,超过了总面积的一半,其次为耕地适宜性等级为不适宜的区域,面积为4287.9 km2,约为总面积的30%,然后是中度适宜的区域,面积为1499.32 km2,最少的是勉强适宜的区域,面积仅为494.39 km2。平山县和井陉县耕地适宜性为不适宜面积占比过大,不适宜进行耕作。Cultivated land is the major land use type in Shijiazhuang.Cultivated land is inseparable from food,and is closely related to human production and life.Based on Shijiazhuang’s DEM data,slope data,landform data,topographic undulation data,and administrative division data of cities and counties in Shijiazhuang,combined with geographic information system theory and spatial analysis methods,and using ArcGIS software,the results of the suitability of cultivated land in each city and county in Shijiazhuang were obtained.According to this study,the suitability level of cultivated land in the eastern part of Shijiazhuang is relatively high,while the suitability level of the western and northern areas is relatively low.Shijiazhuang has the largest area of cultivated land suitable for highly suitable grades,which is 7705.96 km2,which is more than half of the total area,followed by the cultivated land suitable grade of unsuitable areas,with an area of 4287.9 km2,which is about the size of the total area 30%,and then the moderately suitable area,with an area of 1499.32 km2,and the least suitable area,with an area of only 494.39 km2.The suitability of cultivated land in Pingshan County and Jingxing County is that the proportion of unsuitable area is too large and it is not suitable for farming.
