摘　　要：数字孪生是实现国土空间智能规划的基础。与传统的工程技术孪生不同,城市数字孪生因其对象中存在动态复杂的人口社会因素,一直以来在人口底数方面缺乏足够的映射精度。这使得目前的数字孪生技术较难提供精准的人口信息以支持城市规划决策。梳理城市数字孪生发展概况及其技术难点,总结当前主流的人口映射方法及其问题,围绕“真实空间、真实人口、真实需求”的逻辑,提出精准映射城市人口底数的创新技术框架。该框架融合以各类政务数据为主的大量数据源,构建面向政务服务需求的人口底数数字化平台。该项技术有助于实现高颗粒度的城市人口分析、精细化的社区公共品供给以及高质量的国土空间规划。Digital twin is one of the fundamental technologies for achieving intelligent spatial planning.Unlike traditional engineering twin technologies,urban digital twins have not achieved sufficient mapping accuracy over a long period of time due to complex population dynamics and social changes,especially fluctuations in population statistics.This limitation has made it difficult for existing digital twin technologies to provide precise population databases necessary for effective planning decisionmaking.This paper reviews the technical challenges of urban digital twins and examines current mainstream population data mapping methods and their shortcomings.It proposes an innovative technological framework for accurately mapping urban populations based on the principles of"real space,real population,and real demand".This framework integrates extensive data from various government sources to establish a comprehensive digital population base through data engineering.The framework enables fine-grained multidimensional analysis of urban population,accurate provision of community facilities,and improved quality of territorial spatial planning.
