摘　　要：“城区范围”是我国国土空间规划体系建构、城乡划分和统计、城镇化政策制定的重要地理空间基础。本文采用理论研究与实践相结合的方法,首先分析我国当前“城区范围”的现状问题,对相关概念及划定方法进行梳理,结合国际经验,提出我国的城市实体地域概念即“城区范围”,进而提出“城区范围确定”方法;选取115个城市对“城区范围确定”方法进行实践和验证,探讨该方法的科学性、合理性和可操作性;经过反复实践、优化,最终形成了可用于全国设市城市的“城区范围确定”技术流程框架。“Urban built-up area”is an important geospatial basis for establishing the territorial planning system,urban-rural division and statistics,and formulation of urbanization policies in China.Based on both theoretical research and practice,this paper analyzes current problems concerning urban built-up area in China and summarizes its relevant concepts and delineation methods.The paper puts forward the concept that the physical urban built-up area is the urban built-up area based on the international experience,as well as the method for“urban built-up area delineation”.Taking 115 cities as examples,it confirms the scientificity,rationality,and operability of the method.After repeated practices and optimizations,a technical framework for“urban built-up area delineation”is finally formed,which is applicable to all cities in China.
