面向国土空间规划的地表变化监测体系构建与实践研究OACHSSCD

To improve the governance efficiency of national spatial planning under the framework of"Multiple Plans Integration",this paper addresses the current issues in the monitoring system,such as fragmented multi-source data,delayed dynamic response,and insufficient cross-departmental collaboration.Based on theories like"terrestrial surface system evolution theory"and"multi-source heterogeneous data fusion theory",an integrated terrestrial surface change monitoring technology system oriented to national spatial planning is constructed.This system encompasses four levels:space-air-ground-sea data perception,intelligent fusion processing,dynamic simulation and early warning,and full-process support for planning practices,forming a closed loop of"data-technology-application".Practical verification was conducted in Yulin City,Shaanxi Province.The results show that this system can significantly improve the efficiency and accuracy of natural resource monitoring,construction project site selection,ecological protection,and cultural heritage management,providing reliable technical support for refined governance and sustainable development of national spatial planning.
