摘要

Based on index data during 2005-2015, evaluation index system of ecological resilience was established based on concept analysis of ecological resilience. Shenzhen, Dongguan and Zhuhai in the Pearl River Delta were taken as research objects in this paper. Using principal component analysis, error brought by artificial subjectivity could be eliminated, and the selected 6 indexes were simplified into 3 indexes for comparative analysis. The research results showed that ecological resilience at Shenzhen, Dongguan and Zhuhai in research period rose in the fluctuation. Moreover, its change cause was analyzed simply, and some countermeasures of maintaining and improving ecological resilience were proposed. The research could provide basis for making relevant policies and regulations of urban planning and expansion.
