黄土高原和陇南山地泥石流防治研究现状分析

Prevention and Control of Debris Flow in the Loess Plateau and Longnan Mountain Area

甘肃省地处青藏高原、内蒙古高原和黄土高原的交汇地带,降雨集中,暴雨频发,地质条件复杂,是全国地质灾害最严重的省份之一。其中,泥石流灾害分布广,爆发频繁,危害严重。我国泥石流研究已有60多年的历史,但区域的差异性、泥石流种类的多样性和泥石流形成、运动和堆积过程的复杂性,给泥石流防治工程的勘察、设计造成了诸多不便。本研究扼要总结我国60多年来的泥石流研究成果,为西北黄土高原区、陇南山地泥石流灾害防治提供借鉴和指导。

Gansu province is located at the intersection of the Qinghai-Tibet plateau,the inner Mongolia plateau and the loess plateau,with concentrated rainfall,frequent rainstorms,and complex geological conditions.It is one of the provinces in China with the most serious geological disasters,where the debris flows are widely distributed with frequent outbreaks.The research on debris flow in China has a history of more than 60 years,but there still remains many issues to be addressed primarily due to the regional differences and the diverse types of debris flow,as well as the complexity of its formation,movement and accumulation process.This study briefly summarizes the debris flow research of more than 60 years in China to provide a reference and guidance for the prevention and control of debris flow disasters in the loess plateau and Longnan mountain area.
