| 摘要 |
Extensive vegetation restoration practices have been implemented to control soil erosion on the Loess
Plateau, China. However, no strict guidelines are available to determine the most suitable plant species
for vegetation restoration within a given area. The objective of this study was to quantify the changes
of each component (soil water storage, surface runoff, and actual evapotranspiration) of a water balance
model and soil loss over time under eight different vegetation types, and to further determine the optimal
vegetation type for soil and water conservation and sustainable ecological restoration on the steep slopes
(>25) on the Loess Plateau. The results indicated that vegetation type substantially affected soil water
storage and that the greatest soil water storage in both the shallow (0–2 m) and the deep soil layers
(2–5 m) occurred under Bothriochloa ischaemum L. (BOI). Vegetation type also affected surface runoff
and soil losses. The most effective vegetation types for reducing soil erosion were BOI and
Sea-buckthorn (Hippophae rhamnoides L.), while Chinese pine (Pinus tabulaeformis Carr.) and Chinese
pine + Black locust (Robinia pseudoacacia L.) were the most ineffective types. Soil water dynamics and
evapotranspiration varied considerably among the different vegetation types. A soil water surplus was
only found under BOI, while insufficient water replenishment existed under the other seven vegetation
types. The higher water consumption rates of the seven vegetation types could result in soil desiccation,
which could lead to severe water stresses that would adversely affect plant growth. This study suggested
that both vegetation type and its effect on controlling soil erosion should be considered when implementing
vegetation restoration and that BOI should be highly recommended for vegetation restoration
on the steep slopes of the Loess Plateau. A similar approach to the one used in this study could be applied
to other regions of the world confronted by the same problems of water scarcity along with the need for
vegetation restoration. |
