Phenological Information is strongly characterized by its Locality and Temporali ty. It is one of the typical spatio-temporal data, which plays an important role in global environmental change research. Strengthing the Informationalizing pro cess and spatio-temporal change analysis of phenological information are needed to exert its role in the global environmental change to the best. The article poin ts out the necessarity of phenological informationalizing. Then with plant phen ological information about 30 years, and by using GIS Method, we have carried ou t the studies on spatio-temporal query, saptio-temporal change analysis on pheno logical information.
