Urban Ecological Environmental Quality Evaluation System Research

Abstract:

The paper extracts the urban ecological environmental quality evaluation index, based on hierarchical analysis model, the integrated use of "pressure-state-response" model, through the frequency statistics method, factor comparison method and expert evaluation method and so on to set up urban ecological environmental quality evaluation system in nearly a decade based on the related data of environment quality evaluation of Zhengzhou city. Results show that from 1998 to 1998, Zhengzhou ecological environmental quality rises year by year, the ecological environment on the basis of good for Zhengzhou city ecological security evaluation and management.
