Eco-environmental Assessment of the Low Hilly Area Based on Matter-element Analysis Method: A Case Study of Pingdingshan City, China

摘要

On account of the ambiguity of the concept of eco-environmental quality and the incompatibility of evaluation, the paper takes regional eco-system as "Natural - Economic - Social" complex, with the using of Matter-element Analysis Method, selects the 2012 statistics data source of the study area, gives an effective eco-environmental evaluation of the hilly areas in Pingdingshan city by the calculating of Euclid approach degree. The evaluation results show: Euclid approach degree pHj (City center) >pHj (Lushan) >pHj (Ruzhou) >pHj (Baofeng), while the number is between 2 and 3. It showed that the eco-environment quality in Pingdingshan hilly areas is good, waiting for further improvement. It offers the scientific basis and countermeasures for the restoration and further development of the eco-environment in this area.
