الملخص الإنجليزي

Qualitative climato-genetic geomorphology has nearly reached the limit of its contribution.

Nevertheless, the effect of the climate is real.

For karst development, the availability of water is the key climatic factor.

Besides the mentioned karst of temperate warm and humid climate, there are two extremes of karst development: karst of hot and extreme dryness and karst of extreme cold.

There are differences in the relative influence exercised by the various controls.

Precipitation is short but violent while evapotranspiration is very high.

Yet evapotranspiration could be reduced due to fast underground infiltration, scarce soil cover, infiltrating rain-water; the least aggressive of all factors.

Fast percolation of water and no means to enrich it by adding CO2 are the reasons behind the phenomenon that on the karst of the arid climate there is less of surface karstification and more intense underground solution.

Returning to the title question it can be said that it is not appropriate to speak strictly of “arid karst” but of “karst in arid region”.

Nevertheless, there are karst features which are not common or even inexistent in the karst out of arid regions and so it is not wrong to say that there can be also an arid karst.
