Evaluation of regional ecological carrying capacity: A case study in Xiong’an New Area

Abstract

Evaluation of regional ecological carrying capacity refers to evaluation of regional ecosystem carrying capacity for economic and social sustainable development requirement within a certain period of time under premise of ensuring ecological resilience (recoverable) and sustainability. Taking Xiong’an New Area as an example, through correlation analysis method and principal component analysis method, evaluation index system of ecological carrying capacity is designed from three dimensions of green governance, green production, and green life. Then ecological carrying capacity of the New Area from 2015 to 2020 is evaluated based on fuzzy comprehensive evaluation method, and evaluation results are 0.2436, 0.2646, 0.3404, 0.4256, 0.5007, and 0.5652, respectively, with an average annual growth rate of 18.33% and showing a steady growth trend. Finally, some countermeasures to enhance ecological carrying capacity are put forward, mainly including to continuously promote ecological dredging project of Baiyang Lake in the New Area, optimize industrial structure and strict control pollution emissions, and promote green life style of “green transportation + clean energy.”
