Understand the basic systems of environmental protection in China, such as environmental evaluation system, three simultaneous acceptance system and total control system. The related books recommend the Collection of Laws and Regulations Related to Environmental Impact Assessment (version 20 10) compiled by the Environmental Engineering Assessment Center of the Ministry of Environmental Protection, covering the main laws and regulations, policies, management systems and industrial policies involved in environmental protection.
