[交流] 马尾松翻译中译英修改，谢谢啦！

尽管马尾松适应性强，耐干旱、贫瘠，是我国南方地区荒山绿化的主要先锋树种之一，由于人为或自然的因素，有很大一部分林分结构差、生产力低，森林生态系统内组成成分下降，林下植被稀少，林地土壤受到严重侵蚀，整个林分表现为涵养水源、固持土壤等生态效能低劣。由此可见，南方马尾松林的水土保持作用有限。
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.
请大家帮忙修改一下！

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.
