摘要
地质灾害的形成原因有自然的也有人为的,矿山泥石流就是由人为因素为主导,在矿山一带沟谷内形成的。由于物源堆存量和地域短时降水量大小的不同,使灾害发生的规模和对附近居民带来的影响也各不相同。该文以保定西部矿山泥石流特征为例,弄清地质灾害的发生机制和发展规律,对防灾减灾、环境保护及灾害治理工作有着极其重要而深远的意义。
Origins caused geological disasters are composed of natural factors and human factors.Mine mudflow is formed in valley and caued by human factors.Due to different stockpiling of materials and short-term precipitation,the scale of the disasters and the impacts to nearby residents are different.Therefore,the understandings of mechanism of geological hazards and development law are important in disaster prevention,environmental protection and disaster management.
