| 摘 要： | 本文介绍了在地貌及土壤类型均较复杂的低山丘陵区,利用航片在概查后依中地貌为单元进行样区详查的结果.另结合立体观察,分析了各种土壤的定性特征与影响土壤判读的干扰因子.采取的土壤判读方法是从识别地貌、岩性、植被(指示植物)和土地利用类型入手,结合其他环境条件的分析,间接判读土壤至土属一级.经试验,土类、亚类与土属的定性精度依次为98.6%,92.5%及86.3%.定量(图斑界线)精度为75.3%,如扣除在航片上彼此难以准确定界的紫色土(自然土壤)与耕型紫色土图斑,则为86.6%.

| Abstract: | Present paper deals with the application of air photo-analysis and interpretation of the soils in the hilly region with more complex landforms in combination with detailed soil survey following reconnaissance survey along selected lines in model aeras with typical landforms.The qualitative features of soils and the factors interfering soil interpretation were analysed by stereoscopy.The soils were discriminated by landforms,rock types,vegetations (indicator plants),and land use patterns in combination with analysis of other envionmental conditaons.The soils could be discriminated from the level of great group to that of genus.The results obtained showed that the qualitative interpretation accuracies were 98.6%,92.5%,and 86.3% respectively at the level of great group,subgroup,and genus.The quantitative accuracy (of bounderies between aeras) was 75.3%.It amounted to 86.6%,if the areas of natural and cultivated purple soils which were difficult to discriminate were deducted. |
