| 摘 要： | 自我国全面建成地理国情普查成果库之后，工作重心由全面普查变为重点监测。不论普查还是监测，准确地对地表覆盖进行分类一直是工作的重点和难点。在常态化监测阶段，把握地表覆盖分类成果的主要质量指标，归纳其诸如变化率、变化区域分布、变化类型，分析影响其成果质量的主要因素，对监测生产组织及质量控制具有非常重要的作用。

| Abstract: | After China has completed the database of general survey of geographical conditions, the focus of work has changed from general survey to monitoring. No matter in general survey or monitoring, it is always the key and difficulty to classify the surface cover accurately. In the stage of normalization monitoring, it is very important for production organization and quality control to master the main quality indicators of surface coverage classification results, summarize their change rate, change area distribution, types of changes and analyze the main factors affecting the quality. |
