菌根菌剂及土壤改良剂对退化生态系统的修复潜能分析

The Possibility of Fungi Inoculums and Soil Amendment for Restoring Degraded Ecosystems

生态环境退化是人类目前面临的巨大挑战,受损生态系统的合理、有效修复对人类社会的可持续发展至关重要。由于受干扰后的生态系统稳定性较差,靠其自然演替过程进行恢复,进程会极其缓慢。侧重于土壤改良以及土壤生态平衡的重新构建角度,分析采用不同土壤改良剂生物炭、有机肥以及AM真菌菌剂对退化生态系统改良的潜在可能性,并进一步讨论不同改良剂混合施加可能产生的联合作用及其相互作用机制,试图为退化生态系统的修复以及土壤碳吸收提供新的思路。

The increasing degradation of ecosystems is tremendous challenge for human beings on earth. So the valid restoration methods were been paid more attention to relief the stress on natural systems and to restore the serious disturbed ecosystems. As the stability declines dramatically after severer disturbance, ecosystems＇ natural succession would be slow and not enough to recover. Based on soil improvement, this review tried to analyze the potential of different amendment- biochar, compost and AM fungi inoculums on the restoration of the degraded ecosystems. In order to find a new path for the remediation of disturbed ecosystem and soil carbon sequestration, the combined effect of the three amendments and the mechanics were also discussed in this article.
