Comprehensive Evaluation of the Eco-Environmental Carrying Capacity of Beijing-Tianjin-Hebei Urban Agglomeration

Abstract

In order to study the eco-environmental carrying capacity of Beijing-TianjinHebei urban agglomeration, this paper constructed the evaluation indexes system of the urban eco-environmental carrying capacity of Beijing-Tianjin-Hebei based on the DPSIR concept model, determined the weights of indexes by entropy method, evaluated the urban eco-environmental carrying capacity combined with TOPSIS method, and analyzed the urban eco-environmental carrying capacity of Beijing-Tianjin-Hebei in 2012-2016 through horizontal comparison and longitudinal analysis. The results show that the spatial differences of Beijing-Tianjin-Hebei city's eco-environmental carrying capacity are obvious, showing the characteristics of "strong in the middle north and weak in the south". Since 2014, the eco-environmental carrying capacity of 13 cities in Beijing-Tianjin-Hebei has been significantly improved, and the effect of eco-environmental governance is remarkable.
