城市住区绿化生态效益及其可控影响因素的量化分析
Ecological benefits of greening and related controlling factors in urban residential areas of Hangzhou: A quantitative analysis
摘要
Abstract
Based on the 1 m×1 m high resolution aerial images in 2007 and the 30 m×30 m Landsat 5 TM images in summer 2007, and with the help of GIS and remote sensing image interpretation, this paper calculated the normalized difference vegetation indices (NDVI) representing the overall ecological benefits of greening as well as the six controlling factors, i. e. , multilayer structure height, area ratio of softness to hardness, greening rate, floor area ratio, greening area, and build-ing density, in 30 typical urban residential quarters of west Hangzhou. The contributions of the con-trolling factors to the ecological benefits of greening as well as the quantitative relationships between the overall ecological benefits and the six controlling factors were analyzed by multiple linear regres-sion and correspondence analysis, and some advises were given for the improvement of the ecologi-cal benefits. The contribution rate of the six factors was in the order of multilayer structure height > area ratio of softness to hardness > greening rate > floor area ratio > greening area > building densi-ty , and the contribution of multilayer structure height was far greater than that of the others whereas building density had the weakest effect on the ecological benefits. Correspondence analysis was ef-fective in simplifying a complex data table into an intuitive two-dimensional chart, and thus, a po-tential powerful tool in decision-making for the improvement of ecological benefits of greening in ur-ban residential quarters.关键词
