| 摘 要： | 本文讨论了碳酸盐岩表面喜钙内生地衣的结构特征和生活习性。室内简易的蒸发、吸水试验表明，有生物覆盖的碳酸盐岩表面的失水量和吸水量分别是无生物者的４倍和１１．７５倍；经７０％的酒精、３％的双氧水、５％的甲醛溶液的浸泡３昼夜处理过的样品，其有死生物覆盖者的失水量和吸水量分别是无生物者的４６．２５倍和２．０８倍。这对阐明碳酸盐岩表面生物溶蚀机理有重要的理论理义。

| Abstract: | 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. |
