探讨了利用多分辨率分割生成两种尺度的城市绿地景观。以50像元和300像元的目标分割值生成小尺度和大尺度的景观影像目标层,利用最近邻法分类两个目标层。从两个景观尺度的分类目标层中矢量化提取出绿地信息,计算分析城市绿地斑块形状与景观参数。表明基于分割产生多尺度景观的方法满足城市绿地景观研究的需求。
This paper discusses the two-scale urban green space landscape based on multi-resolution segmentation. 50 and 300 pixels are selected as object segmentation thresholds, the small scale and large scale image landscape object layers are produce, and the near- est neighbor is used for classification of two object layers. From vectorised object classification layers of two landscape scale, the green space information is extracted, the shape and landscape parameter of urban green space are calculated and analysed. The result indicates that the method of multi-scale landscape based on segmentation meets the urban green space research demand.
