丘陵地区田间尺度农地景观坡位划分
运用基于相似度的模糊推理方法对丘陵地区田间尺度农地景观下的地形复杂区域进行了坡位分类,并分别利用土壤物理（土层厚度）、化学（有机质、碱解氮、有效铜和有效铁）和土壤发生属性（土种分布）对分类结果进行了验证,结果表明坡位分类整体上符合研究区的实际地形地貌特征,并能很好地解释土壤物理、化学和发生属性的变化,验证了基于相似度的模糊推理方法在地形复杂区域进行坡位分类的可行性。...

Soil physical, chemical and pedogenic properties were applied to test reasonability of the slope positions segmented. Results indicated that slope positions generally followed the actual feature of the land form and it could well explain the variance of soil physical, chemical and pedogenic properties. Also the results verified the validity of similarity-based approach used in the complex terrain area. Guo Pengtao, Li Maofen, Liu Hongbin,※, Wu Wei, Wang Zhengyin, Yu Mingxuan （1.
