摘　　要：由于地质条件、人口密度、救灾可达性和灾害风险等不同,需要对城市各个区域避难场所的投资建设进行优先度排序。如何利用有限资金既能保证优先投资区域的避难容量达到规定目标,又能实现整个城市防灾避难规模的最大化,是城市防灾规划建设的重要问题。运用最优化计算理论,给出了基于优先度的最优投资双层规划模型,并举例验证了该模型的可行性。Owing to the difference in geological condition, population density, accessibility of disaster rescue and disaster risk, the order of investment in shelter should be made. How to use the limited fund to achieve the goals： guaranteeing the prior shelter to obtain the basic target firstly, then maximizing the overall refuge scale of city is an important problem in refuge planning. Applying optimization theory, this paper brings forward an optimal investment bi-level programming model based on priority, and gives an example to varify the feasibility of the model.
