摘要: 城市地质环境风险性分区评价体系由三级指标体系和三层次用户体系构成。一级指标体系反映城市地质环境风险性分区评价指标；二级指标体系反映城市地质环境条件基础性、城市地质灾害危险性和城市地球化学脆弱性分区评价指标：三级指标体系反映城市地质环境基本组成元素的评价指标。3个不同级别的评价结果主要应用于政府决策机构、城市规划部门、城市管理和建设设计部门3个不同层次的用户。Abstract: The risk evaluation system for urban geoenvironment is composed of three-level risk indicator systems and three user-level systems. The first-level risk indicator system concerns the divisional risk evaluation indicators for urban geoenvironmen- tal risk, which mainly serves the city government decision-making agency. The second-level indicator system involves the divisional risk evaluation indicators reflecting urban geoenvironmental background, geological hazard risk and geochemical frangibility, which mainly serves the city planning agency, The third-level indicator system contains the evaluation indicators reflecting the essential evaluation factors for urban geoenvironmental, which mainly serves the city management and construction and design departments.
