摘　　要：城市公园可视性分析对于提升城市公园景观质量和满足居民游憩需求具有重要意义。文章以长沙圭塘河羽燕湖段公园为例,借助无人机倾斜摄影技术,构建DSM模型和ESRI i3s格式的实景三维模型,通过将GIS传统视域分析与3D视域分析相结合的方式,从平视可视度和俯视可视度两方面来定量分析公园的综合可视度,形成了一套具有普适性的“数据收集—三维模型构建—可视度分析”公园可视性分析技术流程。该技术可以为后续公园景观规划设计提供参考依据,极大地提高了景观评估的科学性和准确性。The visibility analysis of urban parks is of great significance for improving the landscape quality of urban parks and meeting the recreational needs of residents.Using the Yuyan Lake section of the Guitang River in Changsha as an example,this study constructs a DSM model and a realworld 3D model in ESRI i3s format with the aid of UAV oblique photogrammetry technology.It quantitatively analyzes the comprehensive visibility of the park from head-up and top-down perspectives by integrating GIS traditional viewshed analysis with 3D viewshed analysis,forming a set of universal"data collection-3D model construction-visibility analysis"process for park visibility analysis.This technology can provide reference for subsequent park landscape planning and design,greatly improving the scientificity and accuracy of landscape assessment.
