摘　　要：针对地面站系统服务能力评估问题,研究了其评估指标及其计算方法.首先从卫星、地面站两个方面建立了地面站系统服务能力评估指标,并就各个指标以及指标的应用进行了分析.然后给出了两种指标计算方法:FCFS(First Come First Service)方法和启发式方法.最后通过实例仿真,表明该指标及方法能够较好的解决地面站系统服务能力评估问题中的是否增建新地面站、是否在某地面站中增加天线等重大决策问题.To the problem of ground station system service capacity evaluation, this paper studies its evaluating indexes and their computing methods. At First, this paper puts forward the evaluating indexes from two points of view of satellite and ground station, and analyses each index and their application. Then two methods for computing these indexes are given, which are FCFS（First Come First Service）and Heuristic. At last, by an example, it shows that the indexes and methods can solve these decision-making problems, such as adding ground station or not, adding antenna in a ground station or not and so on, which belong to the evaluation problem of ground station system service capacity.
