| 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 10m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30.0km2,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。
