Abstract

The effects of Bahia grass (Paspalum notatum) and its litter on dynamics of soil moisture and water balance were studied by using Lysimeter in the slopeland of red soil.The results indicated that surface runoff coefficient of Bahia grass’ coverage (A), Bahia grass’ mulching (B) and CK (C) was 1.35%, 2.78% and 32.74% respectively.Surface runoff of C was 24.25 times of A and 11.78 times of B.Changing laws of monthly mean soil moisture of A, B and C showed that the effects of ground cover on soil moisture were different because of seasons and that different ground cover could increase or decrease soil moisture.Their annual mean soil moisture was B (27.09%)>A(26.46%)>C(26.27%).There were obvious differences between every gradient of water balance.On condition that precipitation was 1 808.5mm in 2002, the total runoff depth of A, B and C was 1 245.24mm, 1 453.81mm and 1 383.23mm respectively; their evapotranspiration was 562.74mm, 347.91mm and 413.82mm respectively; their annual soil moisture variation was 0.52 mm, 6.78mm and 11.45mm respectively.
