摘　　要：为衔接“三调”数据与《国土空间调查、规划、用途管制用地用海分类指南(试行)》的分类体系,本文从理论层面对该指南分类方式与现行国土调查工作分类方式对比分析至二级类,并提出了一种面向国土空间用地用海分类的“三调”数据转换方法。以海南省某区第三次全国国土调查成果为例,利用本文转换方法完成目标区域数据转换,其中83.14%的图斑量自动转换,2.64%的图斑量经矢量分析转换,14.22%的图斑量结合多源参考数据叠加分析及调查举证信息间接转换。结果表明,本文转换方法减少了人工干预工作量,具有较强可行性,为“三调”数据向国土空间用地用海分类体系转换提供参考。In order to link the data of"the third national land survey"with the classification system of Classification Guide of Land and Sea Use of Territorial Spatial Survey,Planning and Use Control(Trial),this paper compares the classification methods of the guidelines and the current classification methods of land survey work to the second level from the theoretical level,and proposes a"the third national land survey"data conversion method for the classification of land and sea use for land space.Taking the results of the third national land survey in a distric of Hainan Province as an example,this paper uses the conversion method to complete the target area data conversion,in which 83.14%of the map spot amount are automatically converted,2.64%of the map spot amount is converted by vector analysis,and the remaining 14.22%of the map spot amount is indirectly converted by combining the overlay analysis of multi source reference data and investigation evidence information.The results show that the conversion method in this paper reduces the work of manual intervention,has strong feasibility,and provides a reference for the conversion of"the third national land survey"data to the classification system of territorial space and land use.
