摘要:
尝试对城市小尺度绿色空间中植被垂直层次展开水平制图,分步骤对北京西海岸边和庆丰公园东区的绿色空间进行了场地尺度的植被用地和垂直层次调研、分类、制图和量化分析,共划分出5类用地植被类型和19种植被层次类型。通过地理信息系统软件计算显示,2个样本场地以中等垂直层次丰富度的植被结构类型占优。其中庆丰公园场地的高、中层次丰富度植被综合占比有优势,西海场地高层次丰富度植被比例较高。植被垂直层次制图是一种服务风景园林规划设计实践的兼具科学性、直观性、便捷性的空间量化研究方法,既是城市绿色空间场地尺度可行的前期调研手段,也可以为城市中稀缺的绿色空间的评估、保护、管理提供基础。

Abstract:
This research attempts to develop a quantitative green space vegetation layer structure mapping in small-scale urban areas. Site-scale research was applied on two sample sites (Beijing Xihai Waterfront and Qingfeng Park East Area) for the vegetation structure investigation, classification, mapping and quantitative analysis. Five land-use vegetation types and 19 vegetation layer structure types are classified. The GIS calculation results show that, in general, the two sample sites are dominated by vegetation structure types with medium vertical richness. Qingfeng Park East Area site has a higher total proportion of rich and medium structure vegetation layers. Xihai Waterfront site shows the superior of rich structure vegetation layers. Vegetation vertical hierarchical mapping is a scientific and convenient spatial quantitative research method that serves the practice of landscape planning and design. It could not only work as a feasible survey method for site-scale green infrastructure research, but also provide the basis for urban green space assessment, protection and management.
Key words:  landscape architecture  urban green space  green infrastructure  vegetation layer mapping  urban ecosystem service
