    Abstract
  • Karst graben basins are special type of karst landforms, which are widely distributed in southwestern Sichuan and Eastern Yunnan Province. In mountainous areas of karst graben basins, light rainfall takes a big proportion of annual precipitation with short occurrence. with short occurrence intervals. The purpose of this work is to study the spatial variations and the response processes of soil moisture and leaf water potential of apple tree (Malus pumila Mill.) to such light rainfall events. The results showed that,(1) the light rainfall events in the mountainous area can only supply the soil water to the maximum depth of 10 cm, so in the dry season (before heavy rainfall events), soil moisture declines with the depth in the vertical section. Due to the topography of the depression, soil moisture (0-80 cm) and leaf water potential of apple tree gradually increase along the slope direction from the top to the bottom of the depression. Because of geological background differences, the soil moisture in the west slope (soil-rocky slope) is 2.67% higher than that in the east slope (rocky slope), thus, the drought degree of apple trees on west slopes are less than that east slopes. (2) There were 12 times light rainfall events in 8 days which can make the surface soil moisture (0~10 cm) rise slightly, but failed to completely change the characteristics that the soil moisture in the bottom of the depression was higher than that on both slopes and the soil moisture of west slop was higher than that of east slope. (3) Although light rainfall events can only supply the soil moisture of 0-10 cm, some shallow apple roots can absorb water because of the shallow distribution (5-30 cm) of apple roots in sloping areas. On the other hand, light rainfall events could decrease air temperature, increase humidity and reduce the solar radiation, which could reduce the transpiration of apple tree and the water potential of apple leaves. It is indicated that the light rainfall events can significantly reduce the drought degree of apple trees.
