Being aimed at the problems of debris flow in mountain town planning,a comprehensive countermeasure of debris flow disasters mitigation for mountain town is made out.

According to the characters of debris flow and risk controlling condition in mountain towns,The concentric circle theory of geography is introduced in this paper,The concentric circle model for debris risk control in mountain towns is discussed and .

Through research of mountainous town ecological features and structures,it simply analyzes the mountainous town ecological energy-saving design,has significance for promoting the adjusted development of society,economy and ecology and guiding the way of sustainable development.
