摘　　要：Join-based算法是一种著名的空间co-location模式挖掘算法,co-location模式代表的是一组空间特征的子集,它们的实例在空间中频繁的关联。首先描述了Join-based算法的工作原理,然后以挖掘三江并流珍希植物的共生物种问题为例利用matlab进行了程序实现,给出了运行的最优结果。Join-based is a famous algorithm for mining spatial co-location patterns.Spatial co-location patterns are traditionally defined as the subsets of features whose instances are frequently located together in geographic space.Firstly,the working principle of join-based algorithm is described,Then,a plant distributing dataset of ＂Three Parallel Rivers of Yunnan Protected Area＂to mining symbiotic plant species as an example,this paper presents the detailed implementation process of the join-based algorithm in Matlab,and gave out the optimal operation results.
