针对遥感卫星应用中用户人工生成卫星成像需求的难度日益增大的现状，深入分析了用户遥感应用需求到卫星成像需求转换过程中所涉及的领域概念和专家知识，提出一种基于本体和规则的卫星成像需求转换方法。通过构建卫星成像需求转换本体，建立领域的概念模型，同时将相应的专家知识以规则的形式加入本体，并利用本体推理实现了卫星成像需求转换。利用这种方法，可以有效地解除用户人工生成成像需求的负担，极大地降低卫星编程数据申请的门槛，为卫星遥感应用带来便利。

Under the circumstance that the artificial generation of the demand for satellite imagery in remote satellite application is more and more difficult,the field concept and expert knowledge involved in the conversion from the demand for client remote sensing applica-tion to satellite imagery is deeply analyzed and a method of satellite imagery demand conversion based on ontology and rule is proposed. By building the ontology of satellite imaging demands conversion,the conceptual model is established. And adding the expert knowledge to the ontology in form of rules as the basis of conversion,the conversion of imagery demand is realized by taking the advantage of ontol-ogy reasoning. With this method,the burden of manually generating imaging demands on users can effectively relieved,the difficulty for applying the satellite programming data is greatly reduced and the satellite remote sensing applications will be more convenient than be-fore.
