摘要
“砂石化”是我国南方山地河谷区在崩塌、滑坡、泥石流发生发展过程中所伴生的一种灾变现象,视其地理景观,酷似我国西北地区的戈壁荒漠。作者以云南小江流域为例,通过多年的实地考察研究,从理论与实践的结合上,就“砂石化”的形成过程、类型特征和控制对策等进行剖析,以期引起人们对此类灾变现象的关注。
'Desertification'is a catastrophic phonomena companying with the avalanche,landslide and de-bris flow in the southern mountainous valleies in China.Its geographic landscape is very similar to thegobi and desert in the northern China.The authors take the Xiaojiang River Basin in Yunnan Provinceas an example,by the field investigation and research from the combination of theory and practice,toanalyze the formative process,type and characteristics as well as contermeasures,so as to arouse thepeople's attention to this kind of catastrophic phonomena.
