摘要

To evaluate ecological effect of roof greening, AHP and Delphi Technique were adopted to collect qualitative data of roof greening, RS and GIS to collect quantitative data. These techniques greatly promote the rate and precision of data collection and processing, and lay a foundation for quantitative analysis of roof greening analysis. Moreover, weights of all indexes were specified. Exponential weighting statistical evaluation was applied for quantification of single index. On this basis, the collected data were standardized and their role and interaction were analyzed by using multivariate method, integrated and evaluated. Evaluation objects of roof greening ecological effect were appraised comprehensively through qualitative analysis (dominant) and quantitative analysis (secondary).
