水文极限分析中改进自适应重要抽样法的应用分析

近年来，随着国内水资源的日渐紧缺，缺水问题一直是困扰我国的发展和进步，甚至已经成为了世界范围的大问题。同时，也注意到不同城市地区以及不同国家范围内受到极端水事件的各种自然灾害以及人为泄露等原因的影响也不断的增加，促使相关的水分析抽样方法在一定程度上得到了快速的发展。文章就水文极限分析中改进自适应重要抽样法的应用进行了分析和论证。

Application of Improved Adaptive Importance Sampling Method in Hydrological Limit Analysis

With the increasing domestic water resource shortage , water shortage has been troubled China＆#39;s development and progress ,even becomes big problem in the world in recent years.At the same time,we also notice that affected by various natural disasters and man-made leakage, extreme water events are increasing in different area and various countries.This makes the analysis of water sampling method in a certain degree obtaine fast development.Application of the hydrological limit analysis of the improved adaptive importance sampling method is analyzed and demonstrated in the paper .
