土地利用和初始含水量对琼东南黄色砖红壤水分入渗的影响
Impacts of Land Use Patterns and Soil Initial Water Contents on Soil Water Infiltration of Yellow Latosol in Southeast Hainan Island
摘要
Abstract
In this study,a cutting ring infiltration method was used to quantitatively measure the infiltration processes of three different land use patterns under two soil initial water contents from yellow latosol in southeast Hainan Island.Fitting analysis of infiltration processes was also conducted based on three normal infiltration models.The results showed soil water initial infiltration rate,stable infiltration rate and 1 h cumulative infiltration of black pepper plantation were obviously higher than those in grassland and coffee plantation,hence the infiltration capacity of black pepper plantation was the best.Despite soil water stable infiltration rate and 1 h cumulative infiltration of grassland were slightly higher than those of coffee plantation,the overall performance of infiltration capacity between the two land use patterns were almost the same.The infiltration capacity difference among the three land use patterns was attributed to soil texture changes induced by land transformation before crop culturing.Meanwhile,as soil initial water content increased,initial infiltration rate,stable infiltration rate and 1 h cumulative infiltration in the three land use patterns all decreased,indicating soil infiltration capacity reduced with the soil moisture increasing.In addition,the soil infiltration processes were better fitted by Kostiakov and Horton infiltration model than by Philip model,which made the two models suitable for describing soil infiltration in yellow latosol area.Results of this study could be used as references for agricultural production and irrigation strategies making in yellow latosol area of southeast Hainan Island.关键词
