| Abstract: | Based on the research of model and method inland and abroad,a model-Funnel Model using to describe the state of urban eco-security was developed in this research.An indicator evaluation system was set up based on Funnel Model,and the principal components analysis method was used to calculate the press degree index(PDI),sustain degree index(SDI) and response degree index(RDI).Finally,with the comprehensive results of PDI,SDI and RDI related to Funnel Model,the urban ecological security degree index(ESDI) had... |
