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 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. |
