植被与土壤生物群落的反馈调节关系

越来越多的研究表明地上植被和地下土壤生态有着密不可分的联系.地上植被通过根际和凋落物改变土壤理化性质并影响土壤生物群落结构及组成,相反,土壤生物群又通过自身的生理生化过程及行为影响地上植被的多样性.二者通过反馈和负反馈将整个地上与地下生态系统的特异性程度巩固和加强.本文将具体讨论地上植被与土壤生物是如何相互相作用并影响各自的生态特征.
Feedback Relationship of Plant and Soil Biota
There is now increasing recognition of the closely linkage between plants and soil biota.Plants changes both the physical and chemical features of soil and influence the structure and composition of soil community by rhizosphere and litter.On the contrary,soil biota influence plans diversity by physiologically process and behavior.They will consolidate and strengthen the specific of degree about thr entire aboveground and belowground ecosystem by positive and negative feedbacks.We will discuss how the plants and soil interact and influence the ecological biota characteristics each other in this thesis.
