摘要:
黄土洞穴潜蚀地貌在黄土高原地区十分发育。对黄土洞穴的基本类型进行了介绍;调查发现区域上黄土洞穴发育密度由西北向东南呈递减趋势;指出黄土洞穴在不同深度的发育类型和发育程度有很大差别,具有明显的层次性;对黄土洞穴的利弊进行了综合分析,认为黄土洞穴具有双重作用:一方面黄土洞穴本身是一种特殊的地质灾害,不但直接造成严重的水土流失,而且对公路、铁路、油气输送管道、民居等工业与民用建筑等均可造成严重危害,另一方面它也是黄土高原地下潜水藏一种重要的补给与排泄途径。
Abstract:
The loess tunnel, a kind of subground erosional geomorphy, is common in the loess plateau. Firstly, the classification of loess tunnels in the loess plateau is introduced. Secondly, based on field research, the distribution regularity of loess tunnels is discovered, that is, the density of loess tunnels is becoming lower from the northwest to the southeast. Thirdly, both the loess types and density differ in different depth; finally, the benefits and hazards of loess tunnels are analyzed. Results show that the loess tunnel has double significance: on the one hand, as a kind of geological hazard, it can not only result in serious water and soil loss, but also make damages to various constructions such as highway, railway, oil and gas conveying pipes and folk houses. On the other hand, it is a kind of important way that provides and discharges water for the effluent reservoirs in the loess plateau.
