Most vugular stratums distribute beddingly in epigenetic karst belt and submerged flow belt,which form from further denudation of dissolved pores acorss beding.

Karst ecosystem is a ecosystem controlled by karst environment, and epikarst ecosystem is the most active part of material exchange and energy flow in karst ecosystem, it is sensitive to the global carbon cycle in Quaternary, especially in late Holocene.

A discussion of the assessment of ground water vulnerability in epikarst zone of the karst area, Southwest China;

Epikarst zone lies in the shallow surface of carbonate rocks in a irregular shape.

The principle and the method of artificial neural network have been applied to the prediction of variation of groundwater levels in epikarst zone.

As a part of efficient exploitation karst water, the Epikarst water has become an important wellspring for those people living in mountainous area.

Epikarst zone is an important concept in modern karst study.

The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, pene-sedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir.

Epi-Fissure-Karst Zone(EFKZ)is commonly observed in karst mountainous area at the middle latitude of P.
