黄土高原植被恢复策略回顾

 以当前在黄土高原植被建设中出现的植被自我修复的舆论倾向为切入点,论述纯自然观、“草、灌先行”、“适地适树”、“适地适林”等植被恢复策略,试图达到澄清问题的目的。认为“适地适树”并没有错,贯彻“适地适树”,将人工建造和自然修复二者结合起来,建设植被是适宜的,但期望通过“草、灌先行”,顺序恢复森林植被有其困难性。分析表明,“适地适树”的标准需要进一步深入研究。最后讨论植被地带性原则与“适地适树”的联系。

Review on Tactics of Vegetation Restoration in Loess Plateau

Resulting from the tendency toward self-rehabilitation appearing in present vegetation construction in the Loess Plateau, the paper discusses tactics of vegetation restoration such as self-rehabilitation, growing grass or shrub as the first step to restore forests, planting suitable trees in accordance with site conditions for afforestation, and proceeding from suitability between plantation and site for afforestation and so on, in order to clarify some problems. It is considered that the tactics that suitable trees are planted in accordance with site conditions for afforestation would not be wrong. Implementing it and integrating artificial construction with self-rehabilitation to construct vegetation is advisable, but it would be difficult that forests are expected to be restored just like natural succession by growing grass or shrub in advance. The analysis showed that the standards to afforest at suitable site with suitable tree are needed to be studied further. At last, the paper also discussed the connection of the vegetation zonality principle and afforestation of suitable site with suitable tree.
