Abstract: The purpose of this paper is to analyze the impacts of biological energy development on land resource use, covering the supply principles and urgently necessary research directions in order to cope with the requirement of biological energy development.Methods employed include documentation,induction and deductive.The results indicate that the rapid development of biological energy has caused constant expansion of the planting area of energy crops in the world.However,the increase of planting area of energy crops results in the decrease of grain crop planting area, woodland,grassland and spare land,which is dangerous to food security and ecological safety to some extent.It is concluded that land administrators need to comprehensively assess the impacts of biological energy on food security, investigate marginal land that suitable for energy crop planting,determine feasible scales and spatial allocation for energy crop planting,which can provide scientific references for formulating the goal of biological energy development in China.
