- Abstract:
-
Conventional afforestation in hilly area of Loess Plateau is only thought to be possible on loess soils because the local foresters consider the two other main soil types (red clay and bedrock-derived soils) too barren to support trees growth and development. In an attempt to determine whether these soils could also support afforestation, we planted trees on all three soil types in a hilly area of the Loess Plateau near Yan’an city from 1996 to 2005. Our results indicate that large-scale afforestation in loess soils could potentially increase the severity of soil water shortages, degrade the natural environment, and increase the risks of desertification and of serious economic losses because of over-consumption of soil moisture. However, survival rates on red clay and bedrock-derived soils were generally comparable to those on loess for individual species, and were superior to those on loess in mixed-species plantations, with less of an adverse impact on soil water. Hence, both red clay and bedrock-derived soils in low-lying areas with adequate soil moisture could potentially sustain afforestation in hilly area of Loess Plateau.
