Abstract The upper reaches of Fujiang River of Yangtze River Basin is characterized by high mountains and narrow canyons, which results in serious contradiction between local people and land. Due to the good moisture and energy condition, the debris flow disaster areas serve as the main living places for local residents. Therefore, efficient utilization of the debris flow disaster land is one of the most important ways for rural development. Through field survey in the upper reaches of Fujiang River, it is found that the debris flow disaster areas are mainly used as arable land, forest land and construction land, which account for 41.5%, 32.8% and 12.1% respectively. And the total acreage of the 42 debris flow disaster areas is 2.47 km2, and the potential usable land area is 2.12 km2, accounting for 86% of the total survey areas, which means a highly potential land utilization. Three factors were chosen to evaluate the debris flow disaster areas utilization modes, which were soil fertility, water and soil conservation, and engineering geology. The results show that the main potential utilization level of debris flow disaster areas in the upper reaches of Fujiang River was medium and low extent, which account for 88.09%. Therefore, the debris flow disaster areas in the upper reaches of Fujiang River have a broad prospect in utilization. In this paper, the authors took Huangjiaba as an example and attained four debris flow disaster areas utilization use modes, which were village gathering and optimazation mode, modern agricurture mode, water and soil conservation mode and potential civil construction mode. Meanwhile, land utilization advice was proposed for each mode, which can provide some gridance of land development and utilization for local government.
