不同植被恢复模式对生物多样性及土壤有机质的影响

Impacts of different models of vegetation restoration on biodiversity and soil organic matters

在陶瓷工业集中重酸污染区,设计不同空间配置格局"乔灌草、灌草、草本"三种植被恢复模式,研究分析不同植被恢复模式对提高生物多样性和改良土壤有机质的效应,试验结果表明,乔木、灌木和草本植物的合理配置格局,无论在增加地被覆盖、促进土壤动物类群的发展,还是在改善土壤质量方面都优于灌木-草本群落和草本群落。

In order to study the impact of different vegetation restoration pattern on biodiversity and soil organic matter in acid-polluted region, three types of vegetation restoration pattern differed in spatial allocation with tree-shrub-herb communities, shrub-herb communities and herbs only communities separately were set in ceramic industrial region, where serious acid pollutants aggregated. Results indicated that the effects of spatial allocation with tree-shrub-herb plant communities were better than shrub-herb communities or herb only communities, not only lies in the enhancement of vegetation coverage and promotion of soil animal communities, but also in the improvement of soil quality.
