摘　　要：应用缓存技术将中央处理器将要运行的数据文件直接调入缓冲存储器,以提高中央处理器的有效资源利用率和大场景流域模型绘制的实时交互性。基于此目的,探讨了各种存储器之间的差异性以及当前实时交互绘制大场景流域模型所存在的问题,分析了实现缓存技术的方法,并给出了主要的算法步骤,结果表明:应用缓存技术不仅能够充分利用中央处理器的有效资源,而且可以提高大场景流域模型绘制的实时交互性,使绘制大场景流域模型更加流畅、更加连贯。To apply cache technology fold the data files which were going to be operated in CPU to the buffer memory directly, which could improve the resources utilization rate of the CPU effectively and the visualizing of the large scene watershed model in real-time interactive manner. Based on this goal, firstly discussed the differences between all kinds of memory as well as the current questions of the visualizing the large scene watershed model in real-time interactive manner , and then analyzed the methods to achieve cache technology, and presented the main algorithm steps to fold the data flies. The results show that： the cache technique can not only take full advantage of the CPU resources effectively, but also improve the visualizing of the large scene watershed model in real-time interactive manner, which can make the visualizing of the large scene watrshed model more smooth and more coherent.
