                    泥石流学具有明确的研究对象、完整的学科体系和系统的研究方法,完全可以作为一门独立的学科;泥石流是一种复杂的山地灾害现象,研究难度大,研究历史又短,故泥石流学理论体系的成熟还需有个发展过程.泥石流学是一门正在趋向完善的新兴边缘学科.
                
                Debris flow is a mixture flow of water,soil and air between sediment-laden flow and  landslide in mountainous regions. The indexes by which debris flow distinguishes sediment-laden flow,landslide and high sediment-laden now are initisl static shear shress with more than 0, big velocity gradient and large gully gradient.Debris flow science have several branch subjects, including debris flow geography, debris flow structure, debris flow formation, debris flow mechanics, debris flow sedimentology, debris now preventions and control. Thus debris now science system is constituted by those branch subjects. Research methods of debris flow are: ilnfermation system, invedigetion, field observation, model test, experimental analysis and mathematical model, etc. Therefore, debris flowresearch completily has the basic factor to be an independent discipline.Debris flow is a kind of very complex mountain hazard phenomenon. Because it is difficulty research,as well as studied time is shorter,the theory of debris flow science needs a developing period to be ripe. In other words,debris flow science is a new frontior science to intend to bePerfect.
