摘要
本文分析了现行支度判别方法的不足，指出评价灾度时必须充分考虑承灾体对灾害的反应情况，并且根据判别准则的可比性原则，提出了灾度指数的概念，并以此做为灾度评价因子，旨在促进灾度评估工作的定量化、科学化，为防灾减灾服务。
in this article, we analyses the shortage of current means of hazard rate judging. When we determine the hazard rate, we must pay more attention to the disaster bearing bodies. For this reason we suggest a new conception of hazard rate index and use it as a factor to assess the hazard rate.
