云贵高原为什么有那么多“地下河”？
Why are there so many underground rivers on the Yunnan–Guizhou Plateau?
这里石灰岩广布、降水丰沛，地表水顺着溶洞和暗河奔流，常在地表看不见，却在地下汇成大河，个别还会以泉或伏流形式重现。
Widespread limestone and plenty of rain let surface water flow through caves and underground channels, often reappearing as springs or resurgences.

#地下河 #暗河
为什么中国西南喀斯特区的大型天坑常常成串分布在地下暗河的径流路径上?
Why do the giant tiankeng of South China's karst tend to occur in strings along underground river courses?
天坑是碳酸盐岩巨型洞厅的顶部发生大规模崩塌、直通地表后形成的特大型负地形。暗河沿断层和岩层面强烈溶蚀、侵蚀,不断掏空山体,洞顶一旦失去支撑便逐级向上垮塌直至出露地表。由于崩塌点位受伏流通道控制,天坑多呈串珠状展布,重庆奉节小寨天坑即为典型代表。
A tiankeng forms when the roof of an immense cave chamber in carbonate rock collapses catastrophically through to the land surface. Underground rivers corrode and erode rock along faults and bedding planes, progressively hollowing out the mountain until the unsupported ceiling fails in stages up to the surface. Because the collapse points track the buried river channel, tiankeng characteristically line up like beads on a string, with Xiaozhai Tiankeng in Fengjie, Chongqing as the classic example.

#喀斯特地貌 #天坑
桂林一带的山体里,溶洞为什么常上下叠置成好几层?
In the hills around Guilin, why do solution caves often occur stacked one above another in several levels?
溶洞主要在地下水面附近水流缓慢但溶蚀持续进行的部位发育。当区域地壳抬升、河流下切时,地下水位随之下降,原先的洞道被抬升到潜水面以上而废弃,新的洞穴又在更低的位置重新溶蚀扩展。抬升与下切反复交替,山体内便保留下一层层对应不同时期水文面的洞道,桂林的多层洞穴系统正是这段历史的剖面记录。
Solution caves develop mainly where groundwater flows slowly yet dissolves rock continuously, close to the water table. As the crust uplifts and rivers incise, the water table falls, stranding older passages above the new phreatic zone while fresh cavities enlarge at lower levels. Repeated uplift-and-incision cycles leave behind storeys of passages recording successive water-table positions, so Guilin's multi-level cave systems preserve a cross-section of that history.

桂林的“山包泡在水里”的奇景是怎么来的？
How did Guilin's hills-in-water landscape form?
这里大片石灰岩被雨水溶蚀，地下掏空、地面塌陷成峰林和洼地，洼地积水就成了漓江和星罗棋布的碧水。
Limestone here was dissolved by rainwater; the ground collapsed into towers and depressions that filled with water, creating the famous peaks-and-rivers scene.

#喀斯特 #峰林
喀斯特地区雨水不少，为什么常常缺水？
Karst areas get rain, so why are they often short of water?
石灰岩布满裂缝和溶洞，雨水很快漏到地下深处，地表存不住水，所以地上反而干旱。
Limestone is full of cracks and caves, so rain quickly drains underground and the surface stays dry.

巨大的“天坑”是怎么突然出现在地上的？
How do giant sinkholes suddenly appear on the ground?
地下河长期溶蚀石灰岩，把顶部掏空，当岩层撑不住时就整块塌陷，形成一个朝天的深坑，就是天坑。
Underground rivers dissolve limestone until the roof can't hold, then it collapses into a deep open pit—a sinkhole.

#天坑 #塌陷
在喀斯特地下河系统中,落水洞、伏流和天窗是如何把地表水与地下水连通的?
In a karst underground river system, how do sinkholes, sinking streams, and karst windows connect surface water with groundwater?
落水洞是地表水集中灌入岩溶含水层的通道,河水沿溶蚀扩大的裂隙转入地下,便成为伏流。当地下河洞顶塌陷露出竖井,就形成可直接观测水位的天窗。随着溶蚀基准面下降,地下河不断向深部袭夺,地表水系逐步被地下管网取代。
Sinkholes are points where surface water pours into the karst aquifer; when a river disappears along dissolution-widened fractures it becomes a sinking stream. Where a cave roof collapses and exposes a shaft, a karst window forms through which the underground river's level can be observed directly. As the dissolution base level lowers, subterranean piracy captures flow at ever greater depth and the pipe network progressively replaces the surface drainage.

云南的石林是怎么“长”出来的？
How did Yunnan's Stone Forest grow?
厚层石灰岩被垂直裂缝切割，雨水沿缝溶蚀，缝隙越来越宽，留下一根根石柱，看上去像石头森林。
Vertical cracks in limestone widen as rain dissolves the rock, leaving tall stone pillars that look like a forest.

溶洞里从天花板垂下来的和从地上长起来的，哪个叫钟乳石、哪个叫石笋？
In a cave, which is the stalactite and which is the stalagmite?
从顶上往下长、像冰溜子的是钟乳石；从地上往上长的是石笋。记住：钟乳石“石”在顶上垂，石笋在地下“笋”。
The one hanging from the ceiling is the stalactite; the one growing up from the floor is the stalagmite.
