英文摘要Earthworms have an important influence on the terrestrial ecological environment. This study assesses the effect of different earthworm densities on soil water content (SWC) and evaporation in a laboratory experiment. Four earthworm densities (0 no-earthworm, control [C]; 207 earthworms m(-2), low density [LDE]; 345 earthworms m(-2), medium density [MDE]; and 690 earthworms m(-2), high density [HDE]) are tested in soil columns. Results show that cumulative evaporation occurs in the decreasing order of densities: C (98.6 mm) > LDE (115.8 mm) > MDE (118.4 mm) > HDE (124.6 mm). Compared with the control, earthworm activity decreases cumulative soil evaporation by 5.0-20.9%, increases soil temperature to 0.46 degrees C-0.63 degrees C at 8:00, and decreases soil temperature to 0.21 degrees C-0.52 degrees C at 14:00 on the soil surface. Temperature fluctuations reduce with increasing earthworm densities. A negative correlation is found between cumulative soil evaporation and earthworm density (R-2= 0.969,p< 0.001). Earthworms significantly (p< 0.05) decrease the surface SWC loss (0-20 cm) soil layer but increase the subsoil SWC loss (60-100 cm) by adjusting the soil temperature and reducing soil water evaporation. Earthworm activities (burrows, casts horizontal ellipsis ) improve the soil water holding ability by adjusting soil temperature and reducing soil water evaporation. Thus, the population quantity of earthworms may provide valuable ecosystem services in soil water and heat cycles to save water resources and realize sustainable agricultural development.
