Different shrubberies have different effect on soil carbon management index.
结果表明,侵蚀环境下的坡耕地由于人为干扰,土壤碳库含量偏低,退耕营造柠条林可以显著增加土壤碳库各组分含量,并随恢复年限呈显著线性关系,25 a时TOC、LOC和NLOC分别较坡耕地增加271%、144%和204%,仅为侧柏林的32%、30%和29%,碳库指数和碳库管理指数较坡耕地明显增加,增幅分别达到144%和108%,仅为侧柏林的28%和43%;不同灌木林对土壤碳库管理的改善作用不同,恢复年限相同的沙棘林土壤碳库组分含量和管理指数明显高于柠条林,坡耕地营造灌木林后土壤经营和管理水平得到了显著改善,土壤系统向着良性方向转变。

However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.
但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化,西南桦人工林的层次结构有3层,以乔木层占优势,并且有种类多而发达的灌木层,同时,藤本植物欠发达,但是乔木层树种单一,明显仅有一层;山地雨林的层次结构有4层,以乔木层占优势,还有灌木层、草本层和藤本植物,藤本植物种类多,十分发达;乔木层树种丰富,可达38种,乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成,根据重要值的大小排列,人工林和天然林的主要物种组成已经完全不同;并且人工林单优树种明显,而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。
