| 摘 要： | 为进行区域水土流失现状评价及趋势预测,掌握宏观控制因子是必要的。从地质背景出发,分析贵州省地质条件的区域特征与水土流失现状及潜在危险性的关系。结果表明,地质条件是山区区域水土流失的重要影响因子之一,宏观上确定了水土流失危险程度的空间分布规律。同时,划分出6个水土流失分区,并就其未来趋势进行了描述和评价。

| Abstract: | Understanding macro controlling factors is necessary for evaluating actual soil and water loss and predicting future trend. Based on the geological background of Guizhou Province, the relationship between the geological conditions and actual soil and water loss and its potential danger was studied. The results indicate that the geological condition is one of the most important factors affecting regional soil and water loss, which determintes the space distribution of soil and water loss's potential dangerous degree. At the same time, the whole province is divided into 6 sub-areas of soil and water loss and their potential trends are evaluated and described. |
