摘要:
泥石流冲积扇是山区难能可贵的相对平坦土地资源，对其进行开发利用对山区农业经济的发展具有重要意义。以白龙江中游泥石流冲积扇坡耕地为研究对象，通过野外考察，结合室内Quick Bird 10 m分辨率卫星影像解译，选取冲积扇面积、灌溉水源、泥石流频率、防治措施、已开发比例5个评价因子，对白龙江中游泥石流冲积扇坡耕地的分布、开发利用现状、开发潜力进行了分析和评价。结果表明：一是白龙江中游172个泥石流冲积扇总面积约为30.0 km2，占河谷平坦地面积的52.07%；二是泥石流冲积扇在白龙江干热河谷所占的面积相当大，开发潜力高的泥石流冲积扇坡耕地有90个，占总数的52.3%。由此可见，整个白龙江中游区泥石流冲积扇具有很好的开发潜力，其中以沙湾-固水子段的开发潜力最高。
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.
