Stability districts of mining subsidence and application of ecology landscape——Taking dongl ongmen of mentougou in Beijing as an example

It is important that built good geology environment to settlement environment in mining subsidence area. In this paper, the district of geology environment and application of ecology landscape security patterns is discussed. And this paper takes the mining subsidence area of Donglongmen of Mentougou in Beijing as an example to district the geology environment of Donglongmen, analysis specific features, put forward the design tactics of ecology landscape security patterns. It is important to improve the geology environment of mining area and helpful to develop the thinking of landscape design about settlement environment in mining subsidence area.
