| 摘 要： | 通过对彰武北部沙地乔、灌、草、农田、沙丘的土壤水分和物理性质研究得出:沙土表层(0~50 cm)含水量受降雨影响显著,100 cm以下影响不明显;地表植被不同则对水分的保持效果、水分在土壤中的垂直分布(0~300cm)、水分有效性和土壤下渗影响有所不同。

| Abstract: | Research of soil moisture and physical properties of sand under herbs,shrubs,trees,field land and dune showed that soil moisture content of sandy soil layers(0~50cm)was significantly effected by rainfall.The effect was not significant under 100cm.The water retaining effect,vertical distribution of water in soil layers(0~300 cm),moisture effectiveness,soil infiltration were different by different superficial vegetation. |
