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 j oin -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 jo in-based algorithm ， in Matlab and gave out the optimal operation results. ：joi n-based algorithm，co-location patterns，spatial data mining，participation index， Key words Matlab
