摘要
丹东地区的泥石流，主要分布在宽甸、凤城、岫岩三县，泥石流活动影响面积占全区．总面积的５８．３％。区内泥石流首先在宽甸县东部鸭绿江沿岸局部地区发生，然后向西延伸，向南北扩展。新中国建立以来，泥石流活动具有逐年加剧之势。泥石流的加剧，主要是破坏森林资源、不合理堆放废弃土石、过度放牧等人为因素造成的。
Debris flow in Dandong Prefecture mainly distributes in three counties of Kuandian,Fengcheng and Youyan. The area subject to debris flow occupies 58. 3% of the total area. Debris flow happened at first in some area .of east Kuandian County along Yalujiang River, then stretched out to west, south and north of the region. The activity of debris flow has the sharp tendency year by year since the People's Republic of China was set up. Human activities such as destruction of forest, irresonable piling up of wasted and abandoned earth and stone and excessive grazing are main cause for sharpennes of debris flow.
