Abstract: With the Yangtze River being dammed, the Three Gorges Reservoir Area starts to impound water for the first time. It is well known that the construction of the Three Gorges Project attracts the attention of the world. On the basis of the sufficient social investigation and the correlative theories of regional economy and environmental administration, this paper discusses conditions of the environmental safety and security in the Three Gorges Reservoir Area, thoroughly analyzes the defects of current law enforcement mechanisms (including law observation, law enforcement, law application and law supervision), and puts forward suggestions on the construction and perfection of law enforcement mechanisms of environmental safety and security protection. The suggestions are as follows: We could offer environment protection education and technique assistance to the main body that abides by law. In order to improve the observance of the law, we could consummate the public participation mechanisms to get the support from the public. We could establish scientific, effective and unified Reservoir Area's law enforcement mechanisms of environmental safety, make clear the responsibility of the Reservoir Area's administrative law enforcement main body, set up the overt exposition mechanism of the administrative law enforcement, perfect the service mechanism of law enforcement main body, and build the green information internet. We could popularize the environmental group lawsuit, extend the defendant range of the environmental group lawsuit, and reform the advance payment way of the environment litigation cost.

Key words: the Three Gorges Reservoir Area, environmental safety and security, law enforcement mechanism
