摘　　要：土地经济系数是农用地分等中重要的修正参数。论文以上高县为例,对"规程法"和"地统计学法"计算土地经济系数进行了比较分析。通过对样点数据的变异函数模型的分析,结果表明土地经济系数具有很强的空间相关性。在结构分析基础上,本文采用克里格内插(Kriging)法,计算出每个分等单元的土地经济系数。经过样点验证,结果表明"地统计学法"计算的土地经济系数更精确。Land economic coefficient is an important corrective coefficient in farmland classification.With Shanggao County cited for the case study,the article made a comparative analysis of the calculation of land economic coefficient based on Rubrics and Geostatistics.In the article,the Model of Variation Function was used to analyze the data of the soil samples from the county.Results indicated that spatial correlation existed between land economic coefficients.To calculate economic coefficient of each land unit based on the structure analysis,the Kriging method was adopted.Results of sampling verification indicated that the land economic coefficient from Geostatistics method is more accurate.
