- Abstract:
-
Six kinds of plantations in Yuanmou County of Yunnan Province,a typical dry-hot area in the valley of Jinsha River, were selected.Soil moisture was determined with TRIME-PICO-IPH TDR in rainy season (from June to October). Each sample area was selected in triplicate to analysis the variety characteristics of the soil moisture. Soil moisture is vey stable and the variation coefficient is much less in the pure forest of tamarindus indica and its soil moisture content is higher than the others. With the increase of the soil depth, the soil moisture differences among the plantations diminish gradually. The soil profile at 0-100 cm was divided into 4 layers by saving and using the rainfall of soil, i.e. moisture dramatical-change layer, moisture weak-utilization layer, herbaceous plant moisture utilization layer and soil moisture slight-adjustment layer.
