Introduction Aug, 1987: Key lab of System Ecology, CAS Dec, 2006:State Key Laboratory of Urban and Regional Ecology Goals: To develop social-economic-natural complex ecosystems (SENCE) ecology To establish theory and methodology for urban and regional sustainable development To provide scientific and technological support for solving China’s major eco-environmental problems, and for China’s sustainable development. SKLURE Page 3 2. Research fields Research fields: focuses on the ecology of social-economic-natural ecosystems interaction between humans and nature at multiple scales; methodology of ecological assessment, planning and management; multi-disciplinary study on major environmental and ecological problems in China; policy study on urban and regional sustainable development.
