中文摘要：

资源环境承载能力监测预警中一项重要的内容就是资源环境耗损过程的变化趋势测度。本文从资源消耗、环境损坏和生态质量变化角度出发,提出了一种基于资源环境耗损的过程评价方法,即通过计算水土资源消耗、水气环境污染以及生态质量变化,测度资源环境耗损指数,刻画资源环境耗损趋势,并在京津冀地区开展了试评价。研究结果表明：1该评价方法以资源环境耗损变化为基础,力图客观反映区域资源环境变化趋势,从科学架构出发,结合数据可获得性和实际可操作性,综合得出一种科学合理且简单易行的评价方法,有利于资源环境耗损过程评价在全国推广。2试评价结果显示,京津冀地区水土资源利用效率提高趋势明显,近80%的区县处于资源利用高效率类别;污染物排放强度总体呈现下降趋势,但仍然有33%的区县污染物排放处于高强度状态;以林草覆盖率表征的生态质量处于逐步降低状态,年均降低速率约为1.2%。3从指标组合关系上看,水土资源利用效率同时趋于良好的县占比最高（100个,约50%）;效率趋势相异的区县较少（62个）,其中土地资源利用效率趋差而水资源利用效率趋良的区县个数最少（18个）。污染物排放强度变化的指标组合呈现两极分化特征。京津冀地区资源环境耗损趋缓型和加剧型评价单元数量对比为6：1,市辖区的耗损加剧程度比县略严重。

英文摘要：

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 BeijingTianjin-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.
