Prevention and control of debris flow in the small watershed based on ecological landscape remediation: a case study of the Tianchi Lake Nature Reserve in Xinjiang, China

In China, there are massive scenic spots located in mountain areas where debris flow of small watershed, landslide, collapse ,and other disasters are well developed.The debris flow disaster does not only harm the quality of the downstream scenic landscape resources, but also threaten the visitors´ life safety. This paper analyzed the features of debris flow disaster in the Tianchi Lake Nature Reserve in Xinjiang.Based on the previous study of debris flow prevention and control pattern, and the concept of river ecological landscape remediation, this paper scientifically proposed the ecological landscape remediation countermeasures through comprehensively utilization of geological disaster ruined landscape resources, in order to protect natural ecological landscape in the scenic debris flow area. In the disaster area, the method of engineering protection is taken to control debris flow, and in the downstream area the integrated prevention and control pattern are taken, which is combining artificial landscape intervention with natural landscape coordination, in order to reach the aim of the remediation of debris flow disaster in scenic spot and an effective integration of scenic resources in the spots.
