天津市国土空间规划基数转换方案研究

Basic Data Conversion for National Land and Space Plan, Tianjin

国土空间规划是国家空间发展的指南,是各类开发保护建设活动的基本依据。国土空间规划的编制及其中三条控制线、自然保护地和历史文化保护范围的划定内容必须与"一张底图"相对应。将"三调"数据成果转换到国土空间规划用地用海分类(即"基数转换"),其成果是"一张底图"的重要内容和组成部分,也是国土空间规划编制的重要基础。本文以天津市为例,借助遥感影像、现状用地等数据,深化细化用地分类,针对"三调"与国土空间规划现状用地不同的对应关系(如"地类对应""地类归并""地类细分"),分类研究国土空间规划基数转换方法。

National land and space plan is the guidance and foundation for different kinds of preservation and development activities.The planning compilation,and delimitation of three control lines,natural reserves,historical and cultural preservation areas,must stay in accordance with "one base map".The conversion of the third national land survey data into land and sea uses (basic data conversion) is fundamental to the base map and national land-space planning.With Tianjin as an example,facilitated by remote sensing image and current land use data,the paper studies the categorization of land uses in correspondence to the basic data,and the methods of basic data conversion.
