Forest bioenergy is an alternative to fossil energy.Although forest bioenergy is of great value to ease energy supply,there is still a strong call for the research of what impact forest bioenergy plantation will exert on environment if under large scale development.By discussing the resource potential and development status of forest bioenergy,the paper attempts to explore the potential impact of forest bioenergy on environment and give some recommendations to mitigate and even avoid negative impact.
