| Abstract: |
| The effects of different vegetation cover on soil water infiltration characteristics of jujube economic forest were studied by field double-ring infiltration test. The soil water infiltration process of different vegetation cover areas was studied by Philip model, Horton model and Kostiakov model. The results showed that the soil infiltration rate of different vegetation cover areas had the same trend, the initial infiltration rate>the average infiltration rate>the stable infiltration rate; The initial infiltration rate of the soil in the natural grass area was the highest, was 4.9020mm/min. The average infiltration rate and the stable infiltration rate of soil in clearing area were the highest, which were 2.3122mm/min and 1.9528mm/min respectively, and the initial infiltration rate, the average infiltration rate and the stable infiltration rate of the soil in the clearing area and the natural grass area were significantly different. The Horton infiltration model had the best fitting effect on soil infiltration process in different areas. The fitting effect of Philip infiltration model was second, and the Kostiakov infiltration model had the worst fitting effect. |
