摘要:
云南高原东北部的东川是泥石流和冰川发育的典型地区,水土流失严重.对于末次冰期不同阶段的冰川与泥石流发育的区域性特征研究表明,二者显示良好的耦合关系和垂直地带性,冰川主要发育在海拔3000m以上,而泥石流则在海拔2500～2000m以下.在季风影响下,冰川与泥石流的交替发育分别对应于气候的冷暖期.结论对于防御高山河谷区自然灾害的产生以及水土保持均具有重要的实际意义.
Abstract:
Debris flow and glacier development are the typical characteristics in Dongchuan located in the north eastern Yunnan Plateau.The investigations of both the debris flow and glacier regional characteristics from different stages indicated that they have the good coupling relationships and vertical zone property.In research region,the ancient glaciers mainly developed above 3000m a.s.l.,while the debris flow occurred below 2500~3000 m a.s.l.Under the monsoon influence,the glaciers and debris flow in the last glacial developed alternately,corresponding to the cold and warm stages respectively.The important significance of the results can help to protect the natural disaster and water soil erosion.
