摘　　要：为提高农用地定级精度,更加精确地量化定级过程中耕作距离的作用分值,基于高差修正法修正后的研究区道路网,考虑道路级别及通行时间成本,运用ArcGIS网络分析功能,考虑道路级别,以时间成本作为量化耕作距离的依据。结果表明,考虑时间成本的最小时间成本路径法更加贴合实际,能够更好地求取更加精确的耕作距离,为量化耕作距离提供可靠依据,为推进评定耕地质量提升土地利用效率和资源利用率提供科学参考。In order to improve the grading accuracy of agricultural land and quantify the function value of the tillage distance in the process of grading more accurately,based on the road network of the research area modified by the elevation difference correction method,the road level and passage time cost were taken into account,and the ArcGIS network analysis function was used to consider the road level and take the time cost as the basis for quantifying the tillage distance.The results show that the minimum time cost path method considering the time cost is more practical,can better obtain more accurate tillage distance,and provide reliable basis for quantifying the tillage distance,which provide scientific reference for promoting the evaluation of cultivated land quality and improving the land use efficiency and resource utilization rate.
