Abstract
In this paper, the ecological security (eco-security) of Dongjiang watershed in 1988, 1998 and 2007 has been evaluated and the eco-security in 2016 was predicted. The Pressure-State-Response model was used to establish the eco-security index system. The temporal and spatial changes of the eco-security from 1988 to 2007 were detected. At the same time, the eco-security in 2016 was predicted temporally and spatially by using The Markov chain model and the Cellular Automata model (the CA_Markov model). The results show that the eco-security of Dongjiang watershed has obvious space differences. The innovation point is that the relative change rate and CA_Markov model were applied to the study of eco-security.
