- Abstract:
-
The alluvial fan of debris flow is valuable and relative flat land resource and it has an important significance in the development of agricultural economy in mountainous area. The slope farmlands on the alluvial fans of debris flows in the midstream of Bailong River are taken as study object. The distribution and development status of the slope farmlands in the study area are analyzed based on the field investigation and the interpretation of Quick Bird 10 meters’s satellite images. Then, the developing potentiality is analyzed and evaluated by choosing alluvial fan area, water resource for irrigation, debris flow frequency, mitigation measure and developed percentage as evaluation factors. The results show that firstly the total area of 172 alluvial fans of debris flows in the midstream of Bailong River are about 30.0 km2 which accounts for 52.07% of the valley flat area; secondly the alluvial fans of debris flows account for large area in the dry-hot valley of Bailong River, and there are 90 slope farmlands on the alluvial fans of debris flows with high developing potentiality accounting for 52.3% in the total amount. Therefore, the alluvial fans of debris flows in the whole midstream of Bailong River have high developing potentiality, among which Shawan-Gushuizi is the highest.
