| 摘 要： | 研究喀斯特地区岩性对土壤理化性状及抗冲性的影响,对探明石漠化机理具有重要意义。选取黔中喀斯特地区5种不同岩性上发育的表层土壤,分别测定其理化性状和抗冲性。结果表明：岩性对土壤机械组成、容重、孔隙度和有机质含量均有显著影响。碳酸盐岩（石灰岩和白云岩）发育的土壤理化性状最好,砂岩类（长石砂岩和紫色长石石英砂岩）次之,煤系地层土壤结构最差。煤系地层的抗冲性能也显著低于其他岩性组。因此进行喀斯特地区水土流失防治时,应针对不同岩性土壤状况分别治理,尤其加强煤系地层土壤流失防治工作。 |

| Abstract: | Discovering the influence of lithologic discrepancy on soil physical and chemical properties and anti-scourability in karst area is significance of studying the processes of rocky desertification.Five lithological soils in karst region of central Guizhou Province were chosen to measure soil physical and chemical properties and anti-scourability.The results indicated: there were significant differences in soil mechanical composition,bulk density,porosity and content of organic matter among different litholog... |
