| 摘 要： | 石漠化主要形成在由白云岩和石灰岩组成的碳酸盐岩分布区。白云岩石漠化的发生率较石灰岩低。主要原因是白云岩与石灰岩相比，总体特征是风化颜色深、矿物颗粒粗且分布不均匀、硬度大容易破碎、孔隙并口裂隙发育、表面粗糙。白云岩的这些特征有利于物理风化成壤，有利于保存土壤和植被生活，石漠化的发生率就相对较低。

| Abstract: | Rocky desertification mainly formed in the carbonate rock distribution area which made up of dolomite and limestone.The rock desertification incidence of dolomite is lower than limestone.The main reason is: compare with the limestone,the general characters of dolomite are deep weathering color,coarse mineral granule and unevenly distribution,big rigidity and easy to be crack,hole and cranny developed,coarse surface.These characters of dolomite is better for physical weathering into soil,is better for keepin... |
