摘要
以往的土壤图反映了土壤调查者在土壤制图时的思想模型 ,土壤制图单元与环境空间数据的关联可以被重新建模并用以推导形式上的调查规则 .然后这些规则可以被用于对相同地区或其它类似地区的空间信息的重新解译 .本研究将浙江省龙游县已有的土壤调查图与地质图、土地利用现状图、DEM及其派生属性 ,双时相的 TM卫星数据相结合 ,使用分类树方法提取了该地区的土壤制图规则 .精度评价结果表明 。
The existing soil maps reflect the mental models developed by soil surveyors, and the association between soil map units and other environmental spatial data can be remodeled to infer formal survey rules. Then these inferred rules can be applied to reinterpreted the soil type for the same area or another similar area. Based on the existing soil map, geology map, landuse, DEM and its derived topographic attributes, bi temporal Landsat TM imageries, classification trees modeling was used to extract soil mapping rules of Longyou County in Zhejiang Province, China. The result showed that these regional soil landscape rules achieved comparable success to predicting most of soil types of study area.
