Abstract: Based on the present situation of biomass gasification power generation industry in China，this paper proposed a comprehensive risk assessment index system for China＇s biomass gasification power generation industry． The system included five first-level effect factors such as market risk，technical risk，security risk，management risk and environmental risk． Each first-level effect factor covered four sub-factors． Analytic hierarchy processs( AHP) was integrated with fuzzy comprehensive evaluation to calculate the risk grade of biomass gasification power generation industry in qualitative and quantitative analysis． The results showed that the current biomass gasification power generation industry in China had a higher level risk in accordance with the real situation． The construction of comprehensive risk evaluation system was reasonable． The study provided some suggestions and relevant countermeasures to promote the development of biomass gasification power generation industry．
