摘　　要：数字制图是近年来土壤学的研究热点,而将数字制图与砂姜黑土研究相结合,目前国内研究甚少。选取河南省为研究区,获取该区的气候、母质和地形信息,以土壤—景观定量模型,定量获取砂姜黑土土类属性与主要成土要素之间的相互关系,应用该模型来预测土类分布并制图。在土类图的基础上,根据土属高程分布差异,进一步预测土属分布并制图。结果表明,该方法在土类数字制图尺度上与调查结果重合度可达到80%以上,并且可弥补调查缺失地方,同时间接证明砂姜黑土的成土母质为石灰性母质,其差异部分表明人为、地表径流因素对砂姜黑土土类的分布具有重要的影响。在土属数字制图尺度上,与调查结果面积数量和分布趋势大体一致,具体空间分布难于比较,有待于景观模型进一步细化,还需更详细的地形和气候资料,这些可为砂姜黑土数字制图的下一步研究和完善提供指导。Soil mapping plays a vital role in soil science in recent years,while the research between lime concretion black soil and soil mapping has seldom been carried out.This study was held in Henan Province, acquiring the information of climate, parent material and relief. Based on the soil-landscape model, according to the relationship between the properties of lime concretion black soil and main soil forming factors, the lime concretion black soil group was derived in a digital way.Based on the digital map of the soil group ,the distribution of soil genus was anticipated according to the difference of altitudes. The result showed that in the soil group map, the contact ratio of digital and investigative soil map was 80%, and some areas hard to survey could be mapped by digital method.In the soil genus map, the basic area and the trend of distribution between digital and investigative soil map were the same. But both the digital maps needed taking more influencing factors into cousideration, such as the impact of human activities and surface runoff in the soil group map, more explicit climate and relief dates in the soil genus map.
