基于三调的城镇内部建设用地细化调查方法研究

Research on the Detailed Investigation Method of Urban ConstructionLand Based on the Third National Land Survey

三调成果是规划和自然资源管理的底图。为更好地衔接并应用三调成果,本文分析了当前自然资源系统对国土地表利用现状和用途的分类体系及其特征,提出城镇内部建设用地细化调查分类标准基础上,研究提出了以管理数据为基础提取工作底图及城镇边界修正、路网构建、图斑细化、综合用途处理、外业调查、数据库及国土变更衔接方法,为自然资源管理精细化分类调查提供技术参考。

The results of the third national land survey are the base map for planning and natural resources management.In order to better connect and apply the results of the third national land survey,this paper analyzes the classification system and characteristics of the current natural resources system on the utilization status and uses of the national land surface,and proposes a detailed investigation classification standard for urban construction land and studies data-based extraction of working basemap and urban boundary correc-tion,road network construction,map spot refinement,comprehensive use processing,field survey,database and land change connec-tion methods,which provide technical reference for the detailed classification survey of natural resources management.
