福建省长汀县2000年以来在以河田为中心的侵蚀红壤区开展了新一轮的水土流失综合治理,依据“反弹琵琶”的治理理念,总结了侵蚀红壤区生态植被恢复与重建的关键技术之一,即对侵蚀区马尾松林地的“老头松”进行施肥改造以改善植被。施肥后,改造区在林地生物群落特征、小气候特征、土壤理化性质方面,取得了明显的变化,有力地促进了长汀水土流失治理的开展。
Since 2000, Changting County, Fujian Province has carried out a new round of comprehensive management of soil and water loss in the eroding red soil area centered on Hetian. Based on the management concept of “rebounding the lute”, the key technologies for the restoration and reconstruction of ecological vegetation in red soil area are summarized One of them is to improve the vegetation by fertilizing the “old pine” of Pinus massoniana forest in the erosion area. After fertilization, the transformation area has made obvious changes in the characteristics of the forest community biome, the microclimate characteristics and the soil physical and chemical properties, which effectively promoted the development of soil and water erosion control in Changting.
