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。
數字製圖是近年來土壤學的研究熱點,而將數字製圖與砂薑黑土研究相結閤,目前國內研究甚少。選取河南省為研究區,穫取該區的氣候、母質和地形信息,以土壤—景觀定量模型,定量穫取砂薑黑土土類屬性與主要成土要素之間的相互關繫,應用該模型來預測土類分佈併製圖。在土類圖的基礎上,根據土屬高程分佈差異,進一步預測土屬分佈併製圖。結果錶明,該方法在土類數字製圖呎度上與調查結果重閤度可達到80%以上,併且可瀰補調查缺失地方,同時間接證明砂薑黑土的成土母質為石灰性母質,其差異部分錶明人為、地錶徑流因素對砂薑黑土土類的分佈具有重要的影響。在土屬數字製圖呎度上,與調查結果麵積數量和分佈趨勢大體一緻,具體空間分佈難于比較,有待于景觀模型進一步細化,還需更詳細的地形和氣候資料,這些可為砂薑黑土數字製圖的下一步研究和完善提供指導。

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,ac?quiring 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 con?cretion 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 cli?mate and relief dates in the soil genus map.
