Shrub-induced soil property spatial heterogeneity
is common in arid and semi-arid ecosystems and aids
desertified land restoration. However, the effectiveness of
this technique may rely on the plant species used and the
habitat conditions present. To assess the degree to which
planting two native species, Haloxylon salicornicum and
Calligonum polygonoides, facilitates degraded land restoration,
soil and herbaceous plant community properties were
measured 7 years after planting. Soil samples were extracted
at two depths (0–5 and 5–20 cm) from three sub-habitats,
i.e., under the shrub canopy, from alleys between shrubs and
from the open area. Shrub planting increased the quantity of
silt ? clay content (30–39 %); enhanced water holding
capacities (24–30 %); increased the levels of organic carbon
(48–69 %), available nitrogen (31–47 %), available phosphorus
(32–41 %), and electrical conductivity (21–33 %);
and decreased the pH (7–12 %) and bulk density levels
(5–6 %) in the surface layer of soils beneath the canopy. Soil
property changes were more significant at the surface
(0–5 cm) than in the deeper layer (5–20 cm), and were more
pronounced under H. salicornicum than under C. polygonoides.
Furthermore, the density and biomass levels of herbaceous
plants were 1.1 to 1.2 and 1.4 to 1.6 times greater,
respectively, in the shrub alleys than in open area. H. salicornicum
induced more robust soil amelioration and herbaceous
plant facilitative properties than did C. polygonoides.
Artificially planting these shrubs may thus be employed to
restore degraded areas of arid regions.
