| 摘 要： | 根据可溶岩层组中非可溶夹层的出露情况对我国西南岩溶山区峰丛洼地进行了划分,并对不同基岩物质组成的峰丛洼地的土壤、土地类型及植被、坡面形态和地表径流特征及其差异进行了论述。在此基础上对不同基岩物质组成的峰丛洼地土地退化的过程及其差异进行了分析,进而论证了各地貌部位合理的土地利用布局。

| Abstract: | Peak cluster-depressions in Southwest China are classified in accordance with the occurrence of inter-layered clastic insoluble rocks in carbonate rock formation.And then,characteristics and differences in soil and land types,vegetation conditions and slope topography as well as surface runoffs feature in peak cluster-depressions composed of different bedrocks are discussed.Correspondingly,processes and differences of land degradation in these peak cluster-deprssions are analyzed on the basis of the above-mentioned studies.Furthermore,the patterns of reasonable land use in different micro-geomorphic sites are expounded. |

| Keywords: | Peak cluster-depressions composed of different bedrocks Land degradation Land use |
