The paper proposes fuzzy fault tree into GIS product reliability analysis for the fist time. Firstly the paper introduces basic theory of fuzzy fault tree, construction of fuzzy fault tree and triangle number and trapezoid number operation rule.The steps that fuzzy fault tree uses GIS product reliability analysis integration GIS product property,are addressed with an example.finally it summarizes the problems to be solved;
