Ecological Risk Assessment of Yulin Coal Mining Area: Based on the PETAR Method

摘要

In order to unravel the correlation and causality between multi-stressor sources, multi-risk receptors and multi-type ecological effects of the Yulin Coal Mining Area. Through qualitative evaluation, this study preliminarily described the main stressor sources, risk receptors and the largest ecological effect over the Yulin coal mining area and progressive and conductive relation among the stressor sources, risk receptors and ecological effects using the Procedure for Ecological Tiered Assessment of Risk method(PETAR). The PETAR method seems to be operable and effective in evaluating coal mining areas 'ecological risks with multiple risk sources, risk receptors and multi-type ecological effects.
