摘　　要：生态保护红线勘界定标面临边界不规则、碎片化和绵延广等难题,而利用实景三维的真实、立体、时序化特性,可有效辅助边界内业校核分析和预标注等工作。本文以实景三维的尺度特征为研究视角,从数据采集精度、表达内容、覆盖范围3个方面,结合生态保护红线勘界定标对工作底图的尺度要求,分析了其与实景三维尺度特征的关系,并提出多尺度实景三维模型融合应用思路。以重庆市照母山森林公园生态保护红线勘界定标工作为例,分析了多源多尺度实景三维数据在不同环节的应用情况,有效提升了勘界定标工作的科学性和工作效率,为持续进行红线监测监管奠定了基础。The demarcation and calibration of ecological protection red line is faced with problems such as irregular boundary,fragmentation and long extension.With the real,three⁃dimensional and sequential characteristics of 3D real scene,it will be effective to assist the boundary verification and pre⁃labeling key points.This paper takes the scale characteristics of 3D real scene as the research perspective,analyzing data acquisition accuracy,content and coverage.Considering the scale of base map that required by ecological protection red line demarcation and calibration,we analyzed its relationship to the scale characteristics of 3D real scene,and puts forward the application idea of integrated multi⁃scale 3D real scene model.Finally,taking the demarcation and calibration of the ecological protection red line of Zhaomushan Forest Park in Chongqing as an example,the application of multi⁃source and multi⁃scale 3D real scene data in different links is analyzed.We find it effectively improves the scientific and efficiency of our work and will be the foundation for ecological protection red line monitoring and supervision.
