摘　　要：以地处陇中黄土高原南部和秦岭山地北部的天水市为例,通过气候条件、地形条件和土壤养分三个方面的9项指标数据,对天水市耕地玉米的适宜性空间分布做了定量评价。结果表明:天水市耕地种植玉米适宜性情况总体良好。依据自然间断法,分为最适宜、适宜、次适宜和不适宜4个等级,其中最适宜占地面积为1232.48 km^(2),占总耕地面积的22.33%;适宜占地面积3154.38 km^(2),占总耕地面积的57.14%;次适宜占地面积1025.14 km^(2),占总耕地面积的18.57%;不适宜占地面积108.35 km^(2),占总耕地面积的1.96%,该结果可为天水市耕地提高玉米产量和优化种植结构提供重要的参考依据,对天水市耕地的科学管理和可持续利用提供理论指导。A scientific and rational evaluation of the suitability of farmland for corn cultivation in Tianshui City can offer crucial references for optimizing corn yields and the local planting structure.This study takes Tianshui City,situated in the southern Loess Plateau and the northern Qinling Mountains,as a case.Nine sets of index data were sourced from three key aspects:climate conditions,terrain features,and soil nutrient content.Using these,the spatial distribution of corn-planting suitability across Tianshui's farmland was quantitatively assessed.The results indicate that the corn-planting suitability of Tianshui's farmland can be classified into four grades:highly suitable,suitable,less suitable,and unsuitable.The areas corresponding to these grades are 1 232.48 km^(2),3 154.38 km^(2),1 025.14km^(2),and 108.35 km^(2) respectively.These account for 22.33%,57.14%,18.57%,and 1.96% of the total farmland area.The findings of this research can provide theoretical guidelines for the scientific management and sustainable utilization of farmland in Tianshui City.
