| 摘 要： | 泥石流是山区常见的一种突发性固液二相(松散土体和水)混合体在重力作用下沿坡面输移的现象。在其流动和终止的过程中,泥位陡涨暴落,来势凶猛且历时较短,常常冲毁或淤埋铁路、公路、农田,以及水利、国防、通讯和旅游点等工程设施,甚至摧毁厂矿和城镇,对人类生产生活和自然环境造成灾难性后果。我国西南、西北、东北山区、秦岭山脉等地的泥石流活动尤为强烈。文章通过对和龙市东城区34条泥石流沟谷的实际调查资料,系统阐述了该区泥石流形成的因素和原因。境内地形地质条件及地质构造对各类地质灾害的发生起控制作用,降雨条件起触发作用,人类不合理活动对自然生态环境的破坏,又进一步恶化、诱发了灾害。针对灾害形成的原因提出了防治对策,以便对潜在灾害进行调查与防治。

| Abstract: | The debris flow is a common natural geological disaster in the mountain area,which can destroy railways,roads,farmland,water,defense,communications,tourist spots and other facilities,even mine and towns.The activities of debris flow are stronger in the southwest,northwest,northeast mountain area,Qinling region in China.According to the survey data of 34 ravines of debris flows,systematically described the forming mechanism and control measures of debris flow in the study area. |
