摘　　要：分析了分布式数据库HBase的存储模型;结合对HBase集群技术的研究,设计了基于HBase的矢量空间数据存储模型和一种基于MapReduce的并行构建网格空间索引方法,使得海量空间矢量数据的网格索引构建分配到各子节点进行,大大加快索引构建的处理速度;最后,利用HBase集群环境对所提出的方法进行验证,该方法具有较好的可行性和较高的效率。To resolve the problem of massive vector spatial datars storage and query, this paper brings forward a vector spatial data distributed storage method based on HBase. At first, this paper analyzes the distributed storage model of HBase. And then, designs a distributed storage model of vector spatial data based on HBase, and proposes a parallel build index algorithm based on MapReduee. Finally, through experiments, this method is proved to be feasibility, reliability. This experiment shows that using HBase can effectively enhance the speed of massive vector spatial data processing. It provides a good solution for large-scale data-processmg.
