摘　　要：在软件系统规模日益庞大,结构日趋复杂的情况下,分层架构的软件设计方法得到了广泛使用,它有着诸多的优点,但也存在着一些问题,如级联变更、性能损失。针对这些问题,提出了采用设计模式对分层架构的改进方案,并以一个电子报表系统为实例进行了阐述。With the gradually increasing of the software system scale and complexity of software system structure, the layered architecture becomes one of the most common techniques that software designers use to break apart a complicated software system. A lot of profits in development and operation are brought, but there are still downsides such as cascading changing and drawback of performance. A solution to these problems is proposed, which improves the layered architecture with design patterns. And as an example, an electronic reports system is given to expatiate on the solution.
