Proceedings of the 12th International Congress of Speleology, La Chaux-de-Fonds, Aug. 1997. Symposium 8, Volume 1: 300. (2 fig.).
Zhen'an County of Shanxi Province is situated in climatically transitional zone between North and South China, where Yudong (Fish - cave) Underground Stream was formed. The mean annual air temperature here is about 11oC, and 850 mm for mean annual precipitation. The karstified rock is predominately Carboniferous - Permian limestone intercalated with coal measures. Due to the sinkholes in recharge area, Yudong Underground Stream is connected to the peak - cluster depressions, where terra rossa and loess formed. The length of the stream is about 30 km, with catchment area of 85 km2 and flood peak discharge of about 10 m3/s. Because of these characteristics, this area become an important site to study the karst processes. (authors; RB).
