摘　　要：以兰州市"十一五"建设规划中1条二级公路为研究对象,采用GIS空间分析法,应用农用地分等成果,对比分析了不同公路选线在占用土地数量和占用土地质量结构等方面的差异,测算了各路线所占耕地的粮食产能状况,并立足于耕地产能保护目标优选了公路路线,推荐路线可比沿原有高等级公路扩建少损失标准粮产量约20万kg/a。将农用地分等成果应用于公路项目路线设计过程中,有利于从公路建设源头上实现对土地的节约集约利用。With a secondary road in the ＂Eleventh Five-Year＂ project of Lanzhou as the study object,based on the GIS spatial analysis method and agricultural land classification results,the paper comparatively analyzed the quantity and quality of lands occupied by different route selections,measured the crop production capacity of the farmlands covered by each route,and optimized the route based on the target to protect the production capacity of the farmlands,the recommended route could save 200 000 kg/a of crops which might loss in the expansion of the existing highway.The application of agricultural land classification results in the design of highway routes would achieve the economic and intensive utilization of lands.

关 键 词：公路路线选取 农用地分等 土地节约集约利用 粮食产能
