资源简介

摘要: 为定量描述城市绿化垂直分布特征及其与建筑空间的数量配置关系,以匈牙利塞克什白堡市为例,基于多源遥感数据提取城市绿地和建筑物三维信息,采取垂直空间高度抽样方法,量化不同高度层上绿色空间和建筑空间的分布数量,并依据二者配置的数量关系,将高度空间划分为“相对匮乏层”和“相对饱和层”,对比分析了不同功能区的垂直空间配置特征,及其与建筑群结构的相关性。研究结果表明:①住宅区和商业区的绿色空间垂直配置结构相似,但住宅区在配置数量上占优;②因配置数量不足、垂直配置结构单一等因素,导致商业区三层及以下建筑位置在绿化配置数量上处于较低水平;住宅区因高空绿化配置数量远少于高层建筑数量,存在“高空绿色匮乏”现象;③高密度的低建筑群是造成商业区“低空绿色匮乏”的主要建筑结构来源;而忽视高建筑物低密度区的“高空绿化”则是造成住宅区绿色空间匮乏的首要原因。  关键词: 绿色空间配置;  垂直空间分析;  激光雷达;  高空绿化     Abstract: Taking as Székesfehérvár,Hungary a case study,vertical greenery distribution and spatial allocation is studied.Based on the multi\|source remote sensing data,three-dimensional information of urban green space and buildings is extracted.A height sampling method is used to quantify the vertical distribution of green space and building space.According to the spatial allocation relationship,the vertical space is divided into “Green\|deficient layer” and “Green\|sufficient layer”,and the vertical spatial allocation characteristics of different function zonings are compared and analyzed.Case study findings indicate that:(1) greenery vertical structure of residential area and commercial area are similar,but residential area has greater allocation quantity; (2) the first to third building floors in commercial area are considered green-deficient due to the shortage of green space allocation and its monotonous vertical structure,and there is inadequate green space provision for high\|rise building floors in residential area; (3) the major cause for low\|rise green deprivation in commercial area is the high density of low\|rise building structure,and neglecting skyrise greenery results in the high\|rise green deprivation in residential area.
