摘要
在国外4个土壤生态学项目的基础上,结合其他学者的研究成果,从连通网、能流网及功能网3个层次分别阐述了土壤食物网的结构、能流与稳定性。在连通网中,主要描述土壤食物网的功能群、营养位及格局;在能流网中,主要描述了面向过程食物网模型及其应用,主要涉及到土壤中的碳流与氮流;在功能网中,以作用强度为中心,描述了土壤食物网的稳定性问题。
The review here discussed the structure, energy flux and stabiltiy of soil food web on the basis of connectedness web, energy flow web and functional web according to the research results of four soil ecology projects done in the USA, Sweden and Netherlands as well as some related research findings. Soil functional groups, trophic position and patterns within the soil food web were described in the connectedness web. Energy flow web focused on the oriented-process food web model and its application regarding to the simulaiton of carbon and nitrogen minerliazaiton. In the functional web, the stability of soil food web was discussed based the central conception of interaction strength.
