CHEN Zhan-long1,2,WU Liang1,WU Xin-cai1 (1.Faculty of Information Engineering,China University of Geosciences,Wuhan 430074,China;2.China GIS Software Research & Application Engineering Center of Ministry of Education,Wuhan 430074,China)  
Traditional GIS software faces some hot potatoes,for example,industrilization, specialization and high cost.In order to resolve these problems,based on the thorough study of essential and implementation mechanism of platform plugin model,this paper designed the GIS software dynamic configuration model,and analyzed the key technologies of system structure,software dealing with message mechanism,interactive mechanism between plugins and the coherence of dynamic configuration in the realization of GIS software dynamic configuration model.At last, combined with large-scale GIS platform(MAPGIS7.0),this paper gave the practice of this model,and tested the feasibility of GIS software dynamic configuration model.
