英文摘要：

The concept and connotation of energy security is dissected. Through analyzing the serious situation of China＇s energy security, main problems are pointed out such as insufficient supply, coal-dominated energy structure, excessive dependence on oil imports, environmental pollution caused by energy consumption, etc.. Then, four countermeasures are proposed including improving energy efficiency and changing China＇s energy structure; diversifying energy import; establishing a spider-web energy supply strategy and constructing a stable oil strategic reserve system; and promoting environmental conservation. It is considered that only the energy supply, economic competitiveness and environment quality are taken as the three basic elements of national energy security, can the security and sustainable development of China＇s energy be guaranteed.
