摘　　要：自然资源统一调查监测中的地表覆盖成果作为重要的基础性空间数据,将发挥对各类自然资源调查监测的基础支撑作用,其成果质量水平将影响各类自然资源统计、分析、评价结果的可靠性。根据测绘重大工程质量控制实践,为确保最终成果质量,需要制定科学、合理、统一的成果质量评价标准,并开展全面、高效、准确的成果质量检查。本文深入分析了地理国情监测、国土调查等已开展的自然资源调查监测工程中地表覆盖相关数据成果的质量特性,以及相关工程中地表覆盖成果质量评价标准、质量检查技术方法的现状及关键技术需求。在此基础上,探讨了基于定量化指标评定法的地表覆盖成果质量评价技术方法,应用面向对象、深度学习等遥感影像智能信息提取技术辅助的地表覆盖分类精度质量检查技术方法,以及应用新型远程化、增强化外业调绘核查技术辅助的地表覆盖成果外业质量检查技术方法,为自然资源统一调查监测中地表覆盖成果质量控制的实施提供技术参考。As an important spatial data in the unified natural resources survey and monitoring system,the land cover achievement will play a fundamental supporting role for all kinds of natural resource survey and monitoring projects.Hence,data quality of the land cover achievement will be related to the correctness and reliability for the statistics,analysis and evaluation results of various natural resources.According to the practice of quality control of major survey and mapping projects,to ensure the quality of the final achievement,it is important to formulate scientific,reasonable and unified quality evaluation criterion for the achievement,and conducts comprehensive,efficient and accurate data quality inspection on the achievement.This paper analyzes current situation of quality inspection and evaluation for the land cover achievement in some typical ongoing natural resources survey and monitoring projects,such as the geographical conditions monitoring project and the national land survey.Furthermore,this paper discusses uses quantitative index evaluation method for the quality evaluation criterion,using latest intelligent remote sensing image information extraction technologies for quality inspection of the classification accuracy,and uses latest remote and enhanced field verification method for the field quality inspection of the land cover achievement,which can provide technical references for quality control of the unified natural resources survey and monitoring.
