摘要： 计算机处理海量空间数据时，内外存之间数据的频繁交互导致内存占用高、处理效率低。使用内存池方式调度空间数据可以提高计算机效率。在多种特定地图使用模式下，不同的内存池页面置换算法能有效降低操作过程中的内外存交互，提高空间数据调度效率。实验表明，该算法为内存容量有限的嵌入式设备上的GIS提出了高效处理空间数据的方案。

Abstract: Due to the characteristics of geographical information data, when massive spatial data processed with computer, frequent data interaction between external memory and internal memory will lead to higher occupancy, and lower efficiency. But memory pool can be used to dispatch spatial data and enhance efficiency. Based on a variety of specific map using models, adoption of the technology utilizing different memory pools page replacement algorithm can effectively reducee the interaction between external memory and internal memory. Experimental results show the proposed solution is ideal for GIS system in the embedded equipment with limited memory capacity.

Key words: memory pool, spatial data, page displacement
