| 摘 要： | 根据土壤水分特征曲线分析和野外实地观测,金沙江干热河谷区主要立类燥红土的植被盖度与土壤持水性能和土层厚度呈明显正相关性.区内具有季节性的自然荒漠化过程.季节性干旱、土壤储水和稳水性能差是本区荒漠化的根本原因,水土流失是其直接动力,提出了防治水荒的有效举措.

| Abstract: | Based on the field investigation and the analysis of soil moisture curve,it is clearly showed that there is a peitive relationship between cover rate and soil moisture capacity and soil depth,and a natural degradation process with seasonally. It is suggusted that the basical factor of desertification in the area is water deficit (seasonal drought and low soil water capacity)and the direct dynamic force of desertification is soil erosion, for this reason, some effective countermeasures was presented at this paper. |
