摘要：

选择东莞市4个镇（街）作为珠三角典型高度城镇化地区和第三次全国国土调查试点，针对试点内容设置、试点典型性选择、试点方法、成果和质量控制等全过程进行了总体策划和设计。从调查底图层面提出了数据源精选类别，形成了3套数据组合配置思路。从调查技术层面阐述了内业分析判读、外业调查核实和内业录入整理的3个关键方法实施路径。通过试点：形成了丰富的专题报告、专题报表、专题图和专题库等实验成果，以土地利用现状调查为例分析了各试点区历经快速城镇化后的土地利用差异性和空间格局特征，提出了在涉密基础数据使用、不一致图斑举证、细碎图斑处理、地类认定标准、多源数据空间不套合和标识码核心关联等7个问题环节的具体先验经验和未来需要深入探索提升的方向。试点成果可作为试点区土地精细化管理之用，试点经验可供快速城镇化地区参考之用。

Abstract:

Four towns in Dongguan city in the Pearl River Delta were chosen as a typical urbanization region and as pilot sites for the third national land survey. The overall planning and design involved pilot contents, typical choice, pilot approaches, study route, quality control, etc. Data source category selection was proposed according to the quality of referable base maps for land surveys, and three data combination models were used for comparative experiments. From the perspective of investigative technology, the implementation approach consisted of three key stages: indoor operation for map interpretation or data analysis; field operation for investigation and verification; and final indoor operation for database construction. In this study, pilot exploration and practice utilized special reports, statistical tables, maps, and databases, yielding rich research findings. Taking the land use survey as an example, the differences and spatial pattern characteristics of each pilot area that has experienced rapid urbanization were analyzed. Meanwhile, seven key technical issues were discovered: the use of confidential basic data, proof of inconsistent map spots, processing of tiny map spot, identification standard of land class, spatial mismatch of multi-source data, database structure, and core association of identification code. The advanced and highly efficient implementation measures were studied to provide a series of pilot experiences. The pilot results provide an important basis for meticulous land management during a new period for the four pilot areas. Additionally, prior knowledge and reference samples were provided for the third national land survey in Dongguan or for other highly urbanized areas.

Key words: third national land survey, highly urbanized area, land use, Dongguan
