Abstract:: In order to identify the vertical distribution and variation of soil moisture in different soil types, the soil moisture along depth of 0-600 cm profile under three soil types in the wind-water erosion crisscross region on the Loess Plateau, i.e., check dam soil, loessial soil, sandy soil, were measured and analyzed. The results showed that the soil moisture in different soil types exhibited different vertical distribution. The soil moisture in 100-600 cm was affected significantly by different soil types, and the soil moisture of 0-100 cm was affected insignificantly by soil types when they covered by Caragana Korshinskii or Populus simonii. The trend of soil moisture in 0-600 cm profile under Caragana Korshinskii was: loessial soil>check dam soil>sandy soil, while under Populus simonii the trend was: check dam soil>sandy soil>loessial soil. For the three soil types, different vegetation types mainly affected the variation of deep soil moisture. The soil moisture under farmland and herbs was better compared with that under the shrubs and trees. These results were of great importance for the proper use of water in arid and semi-arid regions.
