It is well known that the loess landscape is one of the most important topological types .As we know ,human is fur-ther capturing the connotation of loess landscape .Nevertheless ,in the past decades ,there is some inconsistent understanding of the semantics on the loess landscape due to the discrepancy among the disciplines ,domains and knowledge .By referencing of the former similar reports ,this paper proposes a novel semantic model of loess landscape according to the ontology .According to this paper ,the new model is composed of conceptions ,rules ,features ,semantic thesaurus and representation pattern .It is not hard to find that every component of the model highly abstract or generalize the basic features of the loess landscape in the different semantic levels .At last ,this paper carries out an analyst example according the semantic model .Of course ,the au-thor will be so cheerful for this report can help to solve the semantic share issue of loess landscape in the future .%黄土地貌景观是非常重要的地貌类型之一，人们对其认识正在不断深化。然而，长期以来，由于不同的学科、应用领域与知识等的差异，导致了人们对黄土地貌景观的语义特征认知上存在着不一致的现象。借鉴前人的相关研究成果，结合本体论的相关方法提出了一种新的黄土地貌景观语义特征描述框架模型。该模型由概念层、规则层、属性层、语义知识库和表达模式构成。不同层高度地抽象和概括了黄土地貌景观在不同语义层次上的基本特征。该研究对于今后解决黄土地貌景观的语义共享等问题具有一定的参考意义。
