摘　　要：针对地理国情监测成果质量复核中如何科学、客观地检查和评价地表覆盖分类成果,使成果复核在质量控制中起到关键作用,基于地理国情监测地表覆盖分类成果特点,通过在成果验收基础上开展针对成果重要质量元素、重点内容的复核检查,以保证全国成果质量的一致性和符合性。本文提出了复核内容与方法,统计从开展成果复核起历年结果表明,分类精度不仅是地表覆盖分类成果质量的控制难点也是短板。通过归纳复核发现的地表覆盖分类成果主要问题,分析产生的原因,为监测生产提出了意见建议。To the land cover classification product of geographic national conditions monitoring, how to scientifically and objectively inspect and evaluate the results is a problem that if quality review can play a key role in quality control. Based on the characteristics of the land cover classification product, it was carried out a quality inspection for important quality elements and key contents on the basis of quality acceptance to ensure the consistency and compliance of the national results. This paper put forward the content and method of review. The results over the years since the review showed that the classification accuracy was not only a difficulty but also a short board in quality control. Through summarizing the main problems of the land cover classification product found in the review, the causes were analyzed, and suggestions were put forward for production.
