物元-层次模型在盐城市地质环境脆弱性评价中的应用

Application of matter-element and AHP model in evaluation of geo-environment vulnerability in Yancheng City

地质环境脆弱性制约着区域的规划和发展,因此,进行地质环境脆弱性评价,可以为区域的发展提出专业建议,减少不必要的投资。从地质环境出发,建立了地质环境脆弱性评价指标体系,运用物元改进的层次分析评价模型,极大地提高了评价精度。

Regional planning and development were restricted by geo-environment vulnerability,so the evaluation on geo-environment vulnerability was essential.Based on geo-environment,the authors established an evaluation index system on geo-environment vulnerability,used analytical hierarchy process evaluation of improved matter-element model,greatly improved the precision of geo-environment vulnerability evaluation.
