    Assessment of carrying capacity of national geological environments in China

    • 摘要: 地质环境承载能力评价是国土空间规划的基础依据。在综合研究中国区域构造稳定性、地质灾害易发程度、土地荒漠化敏感性、土壤质量地球化学背景等地质环境特征与问题的基础上,结合地质环境分区,构建了差异化评价指标体系,运用基于层次分析的图层叠置法,开展全国地质环境承载能力综合评价,将地质环境承载能力分为高、较高、中等、较低、低5个等级,面积分别占国土面积的15.44%、22.43%、26.13%、11.34%、24.66%。揭示了区域地质环境限制性因素及其限制程度的差异。评价成果表明,地质环境承载能力高的地区主要分布在中国东北平原、华中地区、四川盆地等。

       

      Abstract: The assessment of geological environment carrying capacity is the basis of the land spatial planning. Based on the comprehensive study of the characteristics and problems of the geological environment such as the regional structural stability, the prone degree of geological disasters, the sensitivity of land desertification and the geochemical background of soil quality in China, combined with the division of geological environment, a differential assessment index system is constructed, and the layer superposition method based on layer analysis is used to carry out the comprehensive evaluation of the carrying capacity of the national geological environments. The environmental carrying capacity is divided into five grades: high, relatively high, medium, relatively low and low. The area accounts for 15.44%, 22.43%, 26.13%, 11.34% and 24.66% of the land area respectively. The study of different restrictive factors and degree of regional geological environments indicates that the areas with high carrying capacity of geological environment are mainly distributed in Northeast Plain, Central China and Sichuan Basin.
