摘　　要：在顼目主持单位统一指导下，自1991－1994年期间考察了北疆昌吉、呼图壁、玛纳斯，南疆吐鲁番、鄯善、轮台、库车、新和、阿克苏、乌什、疏勒等地的灌淤旱耕人为土，加上疏附、莎车、和田等以前的考察资料，基本上可以代表新疆灌淤旱耕人为土分布较为集中的地区。经系统分类，类型上有弱盐灌淤旱耕人为主、斑纹灌淤旱耕人为土、水耕灌淤旱耕人为土、普通灌淤旱耕人为土，并对其诊断层和诊断特性以及基层分类予以总结研究。Nanjing Institute of Soil Science,Chinese Academy of Sciences,takes change of research on Chinese Soil Taxonomic Classification,we assume study the Taxonomic Classification of Sil -Orthic Anthrosolswith Siltichorizon in Orthic Anthrosols and its diagnostic horizon and characteristics. Based on their diagnostic horizon and characteristics, four soil subgroups are classified, i. e., Pas - Sil - Orthic anthrosols. Mot- Sil - Orthic Anthrosols,Ans - Sil - Orthic Anthrosols and Tup -Sil - Orthic Anthrosols. So,Siltigic horizon is major diagnostical horizon, and organic matter and rnechanical composition in the soil profile are major diagnostic characteristics. The Sil- Orthic Anthrosols in Xinjiang which has been shaped over all the year round irrigation water which has much silt. But now it is main cultivated land,and it is of great importance standing for land disposition of planting industry in Xinjiang area.
