To the recent years the Karst landscape, especially its wonderful scenery, had became the valuable resources in tourism. But many people did not known how.it became the wonder as it is and want to make a deep know how. In respect of this, the Author attempts to make an answer rest on the basis of geology and geochemistry principles. The core of this paper are of two course, five key factors and a series of geo-chemical equilibrium. There are of that the first epoch of corrosion and second epoch of sedimentation of crystallite; local tectonic control, strata condition, water chemical environment,water dynamic energy and bio-chemicalfunctions; the geochemical equilibrium at low temperature and pressure.Besides, the military and economic significance of the Karst landscape as well as its wonderful scenery in SW China (indeed, many of them can be called superb excelling nature) are also specially related.Though, much of them can easily be found, but the more underground wonders, which have no mouth to the surface, are difficult to discover. To this we also have some guideline for application in exploration.
