林业的六大生态工程、热带和温带山区的造林、荒漠化的治理等的植被恢复和绿化,其成效众说纷纭,有过不少的争论,观点多样。但笔者认为植物种类的选择问题并没有引起相关人士足够的重视。从过去的实践来看,以往人们没有意识到植物种类选择的极端重要性。造成这种状况的原因在于植被恢复工程等方面的理念落后,过于看重短期的效应,对工程的长期效用要求不够、缺乏深层次的预测,还缺乏长期的监督和监测机制。植物的适应能力很强,很多栽种的植物成活容易,往往造成人们一定的错觉,实际上,成活仅是一个最基本的要求,而现实要求我们更关心的是植物成活了以后是否需要后期养护、能否自我更新并保持良性循环、生态效益是否显著,这才是最关键所在。
Six major ecological projects in forestry, afforestation in tropical and temperate mountainous areas, desertification control and other vegetation restoration and afforestation have varied widely in their effectiveness, with many controversies and diverse views. However, I do not think that the selection of plant species has caused sufficient attention from stakeholders. From the past practice, in the past, people did not realize the extreme importance of plant species selection. The reason for this situation lies in backwardness of concepts such as vegetation restoration project, overly short-term effects, lack of long-term utility of the project, lack of deep-level forecasts and lack of long-term monitoring and monitoring mechanisms. In fact, survival is only a basic requirement, and the reality requires that we are more concerned about whether plants need to be conserved after their survival, that is, Whether it can self-renew and maintain a virtuous circle and whether ecological benefits are significant is the most crucial point.
