The energy security strategy for energy plant development in marginal land of China.

Along with the continuous development of society and economy in China,energy safety and environmental protection have gained more attentions.Energy plant that is considered as an important source of biomass plays an essential role in the views of energy supply,fossil energy replacement and eco-environmental safety.The development of energy plant in marginal land is becoming an important issue that needs to be solved urgently.On the basis of current situations of energy,resource and eco-environment,the article systematically presents a development framework for energy plant in marginal land.It includes several models,such as energy plant selection,marginal land definition,eco-environmental risk estimation,economic cost analysis and combined revenues evaluation,and then a mathematical method would be adopted for program optimization.Finally,the article analyses merits and demerits of the proposed framework,and outlines the future development.
