As one of the important theories in ecology, niche is widely used
in the natural and socio-economic systems in recent years. The

and urban niche and so on (Costa et al., 2010). The spatial
evaluation of ecological important must also consider the land
demands from socio-economic development and urbanization in
the future. Therefore, considering the scenarios of economic
development and the effects from land-use in the surrounding
area, some scenarios simulations for the ecological importance of
regional space is the research direction using ecological bit cellular
automata (CA) model in the future
