Aiming at the mining brownfield of which the ecological environment is badly worsening, a mining brownfield park based on ecological tectonic is presented to keep ecological safety on brownfield landscape. The landscape ecological security patterns of mining brownfield park constructed by MCR model take the artificial natural ecological patches in brownfield parks as "origins" in ecological security pattern at landscape scale, which means the origin of artificial nature. The origins of artificial natural patches bind each other, and according to island theory model, the resistance contours between every origin forms saddle tangentially. This saddle area would become "strategic points" between different "origins" in ecological energy flow spreading process. By analyzing the selected landscape indexes and comparing with traditional planing design pattern, the ecological security pattern of mining brownfield park and the degree of landscaped fragmentation decline obviously, the landscape isolation diminishes obviously, while the landscape diversity reduces. The degree of landscape dominance and landscape spread increases.
