Abstract

Urban green spaces (UGS) are one of the indispensable elements for design and development of cities. UGS are considered as “lung” of cities as well as one of the elements reflecting the quality of life. The aim of this research is to develop Weighted Urban Green Space Index (WUGSI) for assessment of city wide UGS based on multi criteria analysis of Chandigarh city. The percentage of green, type of green and proximity to green are selected as parameters to study weighted urban green space index. All these parameters were derived from IRS P6 LISS IV data and IRS P6 LISS 4 + Cartosat-1 fused product. NDVI and Object based classification method is used to obtain different layers and then is analyzed using multi criteria analysis to derive the modified green index. The final result shows the distribution of green space in study area consisted of very high quality green, high quality green, moderate quality green and low quality green. The assessment of UGS was carried out sector wise and it was found that developed index is quite useful for assessment of UGS and can be used to identify the planning

城市绿色空间评价指标的构建

城市绿地是城市设计和发展中不可缺少的要素之一。UGS被认为是城市的“肺”，是反映生活质量的要素之一。本研究的目的是在对昌迪加尔市的多标准分析的基础上，建立加权城市绿地指数(WUGSI)来评价城市绿地状况。以绿化百分比、绿化类型和临近绿化为参数，研究加权城市绿地指数。所有参数均来源于IRS P6 LISS IV数据和IRS P6 LISS 4 + Cartosat-1融合产品。采用NDVI和基于目标的分类方法获得不同的层次，然后采用多准则分析得到改进的绿色指数。结果表明:研究区绿地分布由高质量绿地、高质量绿地、中等质量绿地和低质量绿地构成。对城市地陷进行了部门评估，发现开发的指数对城市地陷的评估非常有用，可以用来确定规划
