摘要
为评价神东矿区植被恢复治理成效,选取治理年限分别为5、10、15 a的典型乔木植物群落———樟子松群落,从群落物种组成、指标特征、物种多样性和群落结构等方面分析了群落随治理年限增加而呈现出的发展变化趋势。从分析结果来看,樟子松群落随治理年限增加表现出总体向好的发展趋势,后期基本无需人为干预,能表现出较好的水土保持效果;在5、10、15 a三个治理年限的樟子松群落中,治理年限为10 a的樟子松群落水土保持效果最好。
In order to evaluate the treatment effect of vegetation restoration and control in Shendong mining area,the paper selected typical arbor plant community of Pinus sylvestris var. mongolica community with treatment years of 5,10 and 15 years respectively and analyzed the development and variation trends of the community with the increase of treatment years from the aspects of community species composition,index characteristics,species diversity and community structure. The analysis results show that a) with the increase of treatment years,Pinus sylvestris var. mongolica community shows an overall good development trend and in the later stage,there is basically no need for human intervention,which can show a good effect of soil and water conservation and;b) in Pinus sylvestris var. mongolica community with three treatment periods of 5,10 and 15 years,the effect of soil and water conservation of Pinus sylvestris var. mongolica community with a treatment period of 10 years is the best.
