| 摘 要： | 现行的西南岩溶山地石漠化程度分级标准过于简单,只能表征坡地的无植被覆盖的石质土地面积比例,不能反映石漠化前后地面物质组成和植被景观的变化。本文提出的石漠化分类,是土壤流失程度、石漠化程度和地面物质组成类型的叠加分类。这一分类较全面地反映了石漠化坡地的现今景观特征和石漠化前后的景观变化,可以更好地满足石漠化成因分析、石漠化治理规划编制和治理措施选择的需要。 |

| Abstract: | The present rocky desertification classification for the karst mountain areas of Southwest China is too simplified and it only indicates the ratios of rocky areas with no vegetation to the total area for a land but unable to reflect changes in ground material composition and vegetation due to rocky desertification occurring on the land. A new rocky desertification classification is proposed in this paper. It is an integrated classification of soil loss extents, rocky desertification extents and ground material compositions. The classification indicates not only the current landscape characteristics, but also changes since land desertification on karst slopes. Therefore, it is better to meet the demands for analyzing causes of rocky desertification, making control plans and selecting measures. |
