青海省国土空间规划基数转换研究
Basic Data Conversion for National Land and Spatial Plan in Qinghai Province

以“三调”为基础的基数转换作为国土空间规划底图基数，是国土空间规划编制的基础性工作。本文以青海省甘德县为例，基于“三调”数据，根据“三调”工作分类与国土空间调查、规划、用途管制用地分类的不同对应关系，进行用地分类转换；并对县域内存在的已批未建、已建未批、已拆除的建筑物构筑物三类情形的管理数据分别进行转换，最终形成“三调” + 管理两个层面叠加的甘德县国土空间规划基数。
The conversion of base numbers based on the “Third National Land Survey” as the base map of territorial space planning is the basic work for the preparation of territorial space planning. This paper takes Gander County, Qinghai Province as an example, based on the data of the “Third National Land Survey”, according to the different correspondence between the “Third National Land Survey” work classification and the classification of land and space survey, planning, and land use control, the classification is converted; The management data of the three categories of buildings and structures that have been approved but not yet approved, and those that have been demolished are converted separately, and finally form the base of Gander County’s land and space plan-ning with the superimposed two levels of “Third National Land Survey” + management.
