南迦巴瓦峰地区自然灾害及其对社会经济的影响
|
摘要
南迦巴瓦峰地区自然变异强烈而频繁，地震、泥石流、崩塌与滑坡、雪害、洪水等自然灾害普遍。探讨了自然灾害的特征和规律、灾害的成因及其对社会经济的影响等问题，认为该地区自然灾害具有连锁性、群发性、突发性和频发性；强烈的新构造运动、高山深谷地貌及温热多雨的气候条件等是该地区灾害发生的最主要自然成因。灾害对该区人民生命财产安全、交通运输、山地农业及森林资源等造成严重影响。
Natural mutations in Mt. Namjagbarwa Region take place extremely and frequently.
Natural disasters such as earthquakes, debris, collapses and landslides, avalanches and
floods are existed everywhere. Their characteristics, regulars and causes of formation as well
as their social and economic affects were observed. The sequences suggested that the
disasters can be characterized of chained, grouping, repeated and abrupt features. The main
natural causes of their formation are intense Neotectonic movement, hilly and abysmal
topography, sultry and rainy climate. They do harm to the people and their
property,communications and transportation,montane agriculture and forest reserves.
