Impact of water environmental characteristics in Dry-Hot valley of Jinsha river on soil desertification

  • Liu Gangcai

Based on the field investigation and the analysis of soil moisture curve, it is clearly shown that there is a positive relationship between vegetation coverage rate and soil moisture capacity and soil depth in dry-hot valley of the Jinsha River, and also there is a desertification process with seasonality. It is suggested that the basic factor of desertification in the area is water deficiency (seasonal drought and low soil water capacity) and the direct dynamic of desertification is soil erosion. Some effective countermeasures are presented, of which water-saving planting and irrigation techniques should be firstly applied in the studied area.
