摘要
"瓦拉亚窟"为傈僳语,汉意为"蝙蝠溶洞",3个天然洞口将多个大型溶洞连接成溶洞群;洞口紧邻举世闻名的大怒江,背靠雄奇的高黎贡山,面对险峻的碧罗雪山,西边是风景如画的芭蕉河。瓦拉亚窟溶洞全长约25km,与芭蕉河溶洞相连;洞口高5m,宽3m,洞内宽敞通幽、泥沙铺地、冬暖夏凉,洞内发育石钟乳、石笋、石柱、石幔等洞穴沉积物,洞内岩石上保存有大量的水流凹槽痕迹可以用于确定古水流方向。溶洞的发育经历了早期芭蕉河地下河系统的溶蚀作用、洞内崩塌、侵蚀作用,以及晚期随着地壳的抬升以地表降水为主的溶蚀沉积作用。
The Walayaku is LiSu language,which means‘Karst cave of the bat’in Chinese.Several large Karst caves are connected into Karst cave group by three natural holes.The mouth of the Walayaku Karst cave is close to the world famous great Salween river to the east,backed by the magnificent Gaoligong Mountain to the west,facing to the precipitous Biluoxueshan Mountain to the east,and connected by the pictureque Bajiaohe river to the west.The whole length of the Walayaku Karst cave is about 25 km,which is linked with the cave of Bajiaohe river.The mouth of the cave is 5 meters in height and 3 meters in width.There is spacious and secluded cave hall which develop many kind of cave deposits that include stalactites,stalagmites,pillars and so on,covered silt of ground in the cave.Beside,a large number of grooves on the limestone which can be used to determine the direction of the ancient flow are preserved in the cave.The climatic variation of the cave is subtle,which express warm in winter and cool in summer in the cave.The development of Karst caves experienced the dissolution of the underground river system,the collapse and erosion in the cave at the early period,and dissolution and deposition of the ground precipitation with the uplift of the crust at the late period.
