通过实地考察研究，对东北区泥石流形成的综合环境背景、泥石流活动状况和基本特征、主要类型、分布规律。

Northeast China, accounting for about one eighth of the total national area with an area of over 1.23×10 6 km 2 is one of the important bases of agriculture, forestry, animal husbandry, energy and heavy industry, with vast territory and rich resources. Affected by natural and artificial factors, the regional environment is becoming more and more serious and debris flow occurs almost every year.
