Other Abstract

Soil infiltration characteristic and its influencing factors were studied under five land-cover types in gully drainage areas in Yuanmou dry-hot valley region in this paper. Results indicated that: (1)Differences on soil infiltration capacity among the five land-cover types were significant, especially for the bare land A and bare land B, whose infiltration capacities were much more lower than those of the other three types, which probably is one of the reasons that the corresponding gully heads were still active. (2) The fitting effect of universal empirical equation was the best among the three equations used in the paper. And the fitting result also showed that the ranking sequences of the initial infiltration rate and the stable infiltration rate were the same as woodland>cultivated land>grassland>bare land A>bare land B. (3)Correlation analysis showed that, the ratio between sand and clay, the total porosity, the capillary porosity and the bulk density were all found to have a significantly positive relationship with all of the three infiltration indexes. However, there existed no significant correlation for the non-capillary porosity, the content of organic matter and the initial soil water content with the three infiltration indexes. The principal component analysis also indicated that the soil bulk density, the capillary porosity and the ratio between sand and clay were the three major factors which greatly influenced soil infiltration characteristics in the study region.
