| Hydrological Effect and Karst Significance of Endolithic Lichens on the Surface of Carbonate Rocks in the Longgang Natural Reserve, Guangxi |
| This paper discusses the characteristic of some peculiar texture and habit of calcarous endolithiclichens, living on the surface of carbonate. Experiments on evaporation and absorption indicatd thatthe armunt of moisture loss and absorption of the carbonate rocks with endolithic lichns cover is 4and 11.75 times, respectively ,as much as that of the fresh carbonate rocks without endolithiclichen covers. For samples trealed with 70%alcohol,3%hydrogen peroxide soultion,5%formalinfor 72 hous ,The amount of moisture loss and absorption of the carbonate rocks covered with non-living endolthic lichens is 46.25 ans 2.08 times as much as that of the carbonate rocds without en-dolithic lichen covers.This should be of important theorical significance for the study to expoundthe biokarst erosional mechanism. |
