南方水土流失侵蚀劣地植被快速修复技术分析

Vegetation Fast Repair Technology of Soil Erosion Area in Southern China

南方水土流失侵蚀劣地釆用以类芦(Neyraudia reynediana)促进芒萁(Dicranopteris dichotoma)快速繁衍的生态修复治理方法,种植类芦第2年林地就有大量的芒萁侵入,第3年类芦植丛间的裸露地几乎全被芒萁占满,初步形成以马尾松+芒萁为主的植被群落。该治理方法充分利用了南方气候温暖、雨量充沛、红壤山地芒萁孢子量大等优势,遵循植物生态群落演替规律,仅用3年时间就完美实现了南方水土流失侵蚀劣地快速绿化的目标。

In soil erosion area of southern China,rapid ecological restoration reproduction method of promoting Dicranopteris dichotoma with Neyraudia reynaudiana was adopted. In the second year, plenty of Dicranopteris dichotoma invaded in Neyraudia reynaudiana forest land. In the third year,the bare land in Neyraudia reynaudiana forest was mostly occupied with Dicranopteris dichotoma,and the vegetation community of P/nus massoniana＋Dicranopteris d/chotoma was initially formed.The approach made full use of the advantages in southern China,such as warm climate, abundant rainfall, the large amount of Dicranopteris dichotoma spores in red soil hilly area, followed the rules of plant ecological community succession, perfectly achieved fast greening targets of soil erosion area in only three years.
