Abstract:

China is in the critical period of ecological civilization construction. The ecological security is an essential foundation for ecological civilization construction and sustainable development promotion, which makes it the hot spot for both researchs and managements. Based on the latest research advances in the related fields of ecological security, the development of ecological security assessment model and the dynamics of ecological security management in China have been summarized. The application of the main assessment models (including the pressure-state-response model, ecological footprint model, landscape ecology model and ecosystem service model) are introduced. The development of researches on early-warning of ecological security is also discribed. In the aspect of ecological management measures, with the purpose of guaranteeing national ecological security, the guarantee policies of ecological security is systemically summarized, and the environmental management measures of ecological restoration, ecological conservation redline delineation and "green shield" natural reserve patrol are introduced. Based on the above mentioned contents, an outlook on the research and management of ecological security in the future is provided. It is recommended that the research should pay attention to the spatial match of the assessment units and the temporal dynamics of the assessment. In the meanwhile, the government should attach more importance to potential risk, emerging technology and comprehensive management oriented by ecological functions. The findings of this study could provide references for the study and management of ecological security in China.
