Pinus massoniana is one of the major pioneer species of vegetation reforestation for having good adaptability to drought and poor nutrients in southern China. However, most of the trees are poor in the stand structure, low in productivity due to human or natural factors. The composition of forest ecosystems declining, spare vegetation and severe soil erosion lead to poor eco-efficiency in soil and water conservation.

Pinus massoniana is one of the major pioneer species for vegetation reforestation due to the strong adaptability, preferable toleratcance to drought and infertility in southern China. However, most of those forests show poor stand structures and low productivity owing to the human or natural factors£¬so that the composition of forest ecosystems is reduced, covered with exiguous vegetation and subjected to severe soil erosion, resulting in poor eco-efficiency of such forests in the conservation of water and soils. Accordingly, Pinus massoniana forests play a limited role in water conservation.
