Abstract
To address the challenge of imprecise delineation and fuzzy boundaries of ecological zones in complex terrain regions,this study adopted the Weinan section of the northern foothills of the Qinling Mountains as the study area,and pro-posed a multi-source-data-fusion-based approach for ecological boundary delineation.Starting from the Qinling ecological-conservation scope outlined in the Shaanxi Province Qinling Ecological Environmental Protection General Plan,this paper first performed a preliminary verification of the boundary by integrating remote sensing imagery,basic geographic informa-tion,results from the third national land survey,and sectoral datasets.Next,field surveys and UAV-based aerial photogra-phy were combined to precisely delineate disputed boundaries.Finally,a multi-level argumentation and review process,combined with on-site boundary surveying and monument placement,optimized the line to produce the legally recognized ecological boundary.The results demonstrate that the proposed approach can precisely delineate the Qinling ecological-conservation area within Weinan City,achieving mapping accuracy compatible with a 1∶10 000 scale.The outcome supports zoning plans for Qinling ecological protection,provides clear spatial delimiters for ecological management,supervision,and law-enforcement,and offers an engineering reference for boundary delineation in other complex terrain ecological zones.关键词
