岩溶浸没内涝灾害灾情评估方法探讨

Discussion on the evaluation methods for the disaster condition of karst immersion-waterlogging hazard

岩溶浸没内涝灾害是岩溶区特有的,并且是一种与人类社会经济密切相关的灾害类型。减轻并控制其所造成的危害和影响,对岩溶区的经济持续发展具有重要的意义。岩溶浸没内涝灾害风险评价是指对灾害全过程的综合分析与研究。评价的目的:①对灾害造成的经济损失作出评估;②不断提高人类抗御灾害的认识能力和技术能力。岩溶浸没内涝灾害风险评价方法学是科学方法的跨学科运用,它以岩溶多重介质环境中地表水系为主线,岩溶地下河系为支线,二者相互交叉组成的岩溶地表地下流域网络单元为研究对象,应用地质、地理、数学、物理、化学等多学科的理论与方法,研究由自然和人为因素引起的造成人员伤亡和物质财富损毁的灾害过程,本文将重点对此进行讨论。

Karst immersion-waterlogging hazard is a peculiar hazard in the karst area,which is closely related tothe social economy.To reduce and control the damage and influence caused by the hazard is of great significance to the continuous development of the local economy in the karst area.The risk evaluation of karst immersion-waterlog-ging hazard refers to the comprehensive analysis and study on the whole process of the hazard.The goals of evaluat-ing the hazard are:(1)to estimate the economic loss caused by the hazard,(2)to improve the perceptibility and technical capability of people to resist the hazard.The evaluation methodology of karst immersion-waterlogging hazard is a complex of many different scientific subjectswhich mainly focuses on the surface water system of karst multiple media and secondarily on the karst underground river system,and has the grid unit of karst surface and underground drainage areas composed of the above two systems alternatively as the research object,and employs the theories and methods from many subjects,such as geology,geography,mathematics,physics,chemistry,etc.to study the hazard process of personnel casualty and property loss caused by the natural and manual factors.The paper will mainly discuss the above-mentioned contents.
