To address the issues of low efficiency and insufficient resource utilization in multi-project monitoring,this study proposed the"1+X"change monitoring method.This method extracted change patches through a single monitoring process,facilitating shared applications across multiple projects and effectively integrating remote sensing data resources.Utilizing Fuqing City in Fujian Province as a test area,the study explored and applied the method and conducted statistical analysis of its application effects,so as to further optimize the method.Experimental results demonstrate that the"1+X"change monitoring method significantly enhances the efficiency and completeness of change patch extraction.It can be effectively applied to projects such as national land change surveys,illegal behavior monitoring of natural resources,and annual updates of basic geographic information data.The method reduces production costs and minimizes resource wastage,thereby providing robust support for enhancing natural resource management capabilities.
