论泥石流及其学科性质

目前对泥石流性质的认识还不十分清楚，从而导致对其学科性质的认识还存在着不同的看法，纵观近70年来与泥石流发展有关的学科，通过对50余部代表学科成熟度的中外学术教材和专著的透视可知，地貌学是孕育泥石流的母学科，在泥石流这一学科生长点的发展壮大过程中，新兴的灾害学与其结合得最紧密，从而诞生了一门新的边缘交叉学科－灾害地貌学或称地貌灾害学，泥石流学科性质即定位于此，本文虽是仁者见仁，难免管中窥豹，其目的旨在引起同行的讨论和争鸣，以促进泥石流学科的更快发展。

Debris flow and its subject attribute

Nowadays scientists do not quite know debris now property so that the subject attribute of debris flow is not quite clear up to date. Searching for recent 70 years' developments of subjects relevant to debris now, and studying by about so textbooks related to debris flow, a conclusion fright be drawn: geomorphology is the mother subject of debris now. During the history of debris now research developments, debris flow is closely incorporated with a newborn catastrophology, which creates a new intersect subject-hazard geomorphology, or say, geomorphologic hazard. Debris flow subject is attributed to the subject of geomorphologic hazard. Debris flow research is a scientific object commonly studied by geomorphologists and catastrophologists. To develop debris flow research, requires geomorphologists and catasttrophologists to master much more knowledge of mechanics, engineering and managing science as well as environmental science.
