| 摘 要： | 岩溶洞穴中的土壤作为一类洞穴沉积,具有很好的学术研究价值,但目前利用洞穴土壤来研究水土流失的成果还很少.2010年8月、9月在贵州毕节、清镇、花江的三个洞穴和一条地下河中采取了洞穴土样,然后在室内用比重计速测法对洞穴土壤进行了颗粒分析并将其与地表土壤进行对比研究.研究发现,洞穴土壤颗粒中粘粒含量远高于地表土壤,土壤通过...

| Abstract: | Although soil in karst caves is of great academic values,there is little research on cave soil for water and soil erosion.We sampled soil from three karst caves and a subterranean river located in Bijie,Qingzheng and Huajiang,Guizhou Province in April and May 2010.We measured particle of these soil samples by hydrometer method,and madea comparation between cave soil and surface soil.The result shows that cave soil contains much higher clay content(<0.001mm) than surface soil;soil is transported form surface... |
