摘　　要：从公路自然灾害应急救援点的功能需求、选址影响因素、选址要素(顾客、设施、空间、度量)和选址目标等方面对救援点选址规划特征进行了研究.从公路应急救援的快速反应、集合覆盖、灾害损失最小化3个方面建立了公路网应急救援点的多目标选址优化模型,并探讨了模型的求解算法和求解步骤,通过Lingo软件编程实现了优化目标的求解.最后,通过浙江桐庐公路网的应急救援点规划实例对提出的选址优化模型进行了应用.The characteristics of highway emergency rescue site location planning were first analyzed from four aspects including the functional requirement, location impact factors, location elements （ customers, facilities, space and measurement） and location objectives of emergency rescue site. Based on three objectives in rapid response, set covering and disaster loss minimum, a multi-objectives decision model for location optimization was established. Then the algorithm and procedures of this model were discussed and the optimized objective was achieved through the Lingo programming. Finally, the method of rescue site planning was applied to the Tonglu highway network in Zhejiang Province.
