【摘要】 地质灾害影响评价是实现世界遗产地可持续发展的重要基础。本文选取历史灾害危险性、地质环境条件、遗产地易损性和遗产地减灾能力4个评价要素和18个评价因子:地质灾害点密度、地质灾害规模、地质灾害频度、断裂分布密度、地貌类型复杂度、岩土体稳定性、年均降水量、降水量变异系数、森林覆盖率、人类活动、建筑群或人造工程面积、建筑结构体系、文物数量、物种丰富度、生态系统稳定性、防灾工程、救灾能力、重建能力等构建了评价指标体系,并应用模糊综合评价模型对其评价过程进行了探讨。作者以九寨沟为例对该指标体系与模型进行了实例验证,并认为其能够直观的反映地质灾害对世界遗产地可持续发展的影响,具有一定的操作性和普适性。更多还原

【Abstract】 Rational assessment of the impacts of geologic hazards on World Heritage sites forms the basis for their sustainable development. This paper selects 4 aspects: harmfulness of historical hazards,geological environmental conditions,vulnerability of heritage sites and hazard reduction capabilities of heritage sites and 18 indicators to build an assessment indicator system. The evaluation process is discussed with the application of fuzzy comprehensive evaluation model. Jiuzhaigou is selected as a research area to validate the indicator system and the model. The research shows that it can intuitively reflect the impacts of geological hazards on sustainable development of World Heritage sites. And the method is operational and universal to some extent.更多还原
