论县级国土空间规划“一张底图”的构建及应用

基于县级国土空间规划实施性的管理需求,实现“多规合一”的“一张蓝图”的前提是构建以“三调”为基础的“一张底图”。“一张底图”的构建需要在“所见即所得”的“三调”数据基础上,合理甄别整合各部门提供的必要空间关联动态数据和信息,才能得到附加了管理事权属性的县域全类型国土空间用途底图。结合山东省若干县级国土空间规划实践案例,探讨如何通过“基数转换+数据叠加”的方法,统一不同类型数据的覆盖范围、分类体系和应用方式,构建全类型全覆盖的“一张底图”,并将其应用于国土空间开发保护年度评估、资源环境承载能力评价和国土空间开发适宜性评价以及国土空间规划的“四类空间”初步划定等方面,为县级国土空间规划编制、实施和管理奠定基础。

Discussions on the Construction and Application of"One Base Map"of the County-Level Territory Development Planning

Based on the management need for the implementation of the county-level territory development planning,forming the single base map based on the third land survey is the foundation of satisfying the requirement of"one blueprint"for"multi compliance".The third land survey data are an approximate of reality.It is necessary to intelligently integrate different dynamic and spatially-correlated data from various departments to form"one base map"covering overall territorial development types in the county.By resolving the differences in land coverage,classification system and application methods of existing data,this paper explains the development of the single base map by using the combined methods of base conversion and data superposition in several county-level territory development planning projects in Shandong Province.The paper also helps lay the foundation for county-level territory development planning,implementation and administration by showing the application of the single base map to the annual assessment of territory development and protection,"double evaluation",and preliminary designation of"four kinds of space".
