Wen Jing

In the face of the increasingly prominent overloaded operation of the life support system on earth currently, the ecological environmental problems on a global scale become more and more serious, and the ecological safety of the geographic space attracts extensive attentions increasingly. Based on GIS and space ecological footprint, this paper builds the ecological safety evaluation index system, sets up the evaluation criterion, further designs the space ecological safety evaluation model, and analyzes the evaluation results of the provincial regions of China from 1998 to 2012, so as to have the definite reference significance for promoting the space ecological safety of China.
