Definition and characteristics of distributed combined cooling, heating and power system (CCHP) were briefly summarized. The principle of biomass gasification system was mainly introduced, and several application modes of CCHP based on biomass gasification (BGCCHP) were discussed. At last, the advantages and difficulties of developing BGCCHP in China were analyzed. BGCCHP could realize the cascade utilization of energy coming along with social, economic and environmental benefits and it is an efficient and comprehensive way for biomass resource exploitation and application. 
