Abstract:

Establishing the mechanism of monitoring and early-warning of resource and environmental carrying capacity is an innovative work of comprehensively deepening reforms in China. An important approach to analyze resource and environmental carrying capacity is to measure the trend of resource and environmental depletion. Based on the three perspectives of resource consumption, environmental damage, and ecological quality change, this study developed an evaluation method of resource and environmental depletion and carried out a trial evaluation in the Beijing-Tianjin-Hebei region. The results show that the developed method is effective to objectively reflect the changing trend of resource and environmental conditions in the Beijing-Tianjin-Hebei region. Trial evaluation shows that in the Beijing-Tianjin-Hebei region, water and soil resource use efficiency is becoming better, 80% units are in the type of high efficiency. Pollutant emission intensity continued to decline in the past decade, but there are also 33% units staying in the type of high intensity. The overall ecological quality is in a state of gradual decline and the average annual rate of decline is 1.2%. From the perspective of indicators combination, units whose water and soil resources utilization efficiency increase at the same time have the largest number. The combination of pollutant emission intensity presents polarization characteristics. Resource and environmental consumption is more intensive in city areas than that in the counties.
