With the emergence and development of ecological engineering in China, and also the research and demonstration of Chinese Ecological Agriculture (CEA), in recent 10 years many types of ecological engineering have been appeared in Southern China, they could be classified into 4 typical patterns. These typical patterns are: 1. Ecological Building (EB), such as ecological public toilet, ecological garden, ecological integrated building, farmers ecological household, the combine of ecological building and CEA; 2. Ecological Engineering in Paddy Field (EEPF), like rice-fish system, water caltrop-wild ricestem-fish system, mulberry-silkworm-pig-fish system; 3. Ecological Engineering of Agroforestry Systems (EEAF), as tea-food crops intercropping system, rubber-tea-chicken system, bamboo-chicken system, fruit tree-chicken system, metasequoia-fish-duck system; 4. Ecological Engineering Linked with Biogas (EELB), such as animal (pig)-biogas-fish system, animal (pig)-biogasfruit tree system, animal-biogas-food crops system. Some case studies were presented in the paper. It is showed that these typical patterns have better ecological, social and economic benefits, now they are deeply been extending in southern China.
