["Safe and just operating space" for the sustainable development of the social-ecological system in the Liangzi Lake Catchment, Hubei Province, China.].

The increases of human activities threaten the health of the earth's ecosystem, and pre-sent a big challenge to regional sustainable development and environment conservation. How to maintain a safe ecological environment together with social and economic development is an important issue for sustainable development. Under the theoretical framework of "safe and just operating space", we integrated lake sediment records, environmental monitoring data, and socio-economic data in Liangzi Lake Catchment, analyzed the status of key eco-environmental processes and achievement degree (the completion of the current value of social basic indicators relative to the target value) of residents' social welfare, and constructed a "safe and just operating space" for the sustainability of local social-ecological system.
