摘    要：在洞庭湖的洪水调度过程中,蓄洪垸的分蓄洪调度是洪水调度的关键和难点,而一旦决定使用蓄洪垸分洪时,及时将救灾物质运送到险工险段,或将人员物资疏散到安全地带,是防洪决策必须考虑的一个重要问题.作者利用遥感数据源,在详细分析洞庭湖区域的水位-面积、水位-容积的关系基础上,建立了洞庭湖区域蓄洪调节关系方程,采用运筹学中的多目标交互式决策方法,实现最优分蓄洪方案的建模,并研究了该模型方程的求解方法.然后利用ArcView3.2中的网络分析模块和其提供的二次开发工具AVENUE,进行了安全撤退和物资调配的路径网络模拟研究.该模型的建立,可以减少防汛过程中许多人为因素的影响,从而提高了决策的科学性和准确性.

Abstract: During the process of flood dispatching, dividing itto the flood storage project is the key and difficulty of flood diversion in Dongting Lake. Once this method is decided to be used, quickly displacing the essential goods to the disaster area and retreating the people to the safe area, is the indispensable question of the decision-making, which is also one of the task of the information system. Based on the research about the relationship of the large-area, large-cubage, the flood measure equation of the Dongting Lake is established by the data of RS in this paper. And through the Step Method of operational research ,the flood diversion model is built and its solution method is discussed. By the Network Model of the ArcView3.2 and Avenue-the tool for its second programming language, the best retreat route is analyzed too. Because of the model, the artificial influence is reduced, then the decision is more scientific and exact.
