基于土壤生物空间异质性分析的空间土壤生态学研究

土壤生物以不同的方式改变着土壤的物理、化学和生物学特性。了解土壤生物的空间异质性是很关键的。土壤生态学和空间生态学结合的新的研究领域─空间土壤生态学关注空间在土壤生物种群结构及动态中的重要性。本文通过对土壤生物空间异质性的分析,内容包括空间土壤生态学的提出、土壤生物空间异质性研究的意义、研究方法,重点综述了影响土壤生物分布格局的因素、尺度,土壤生物空间分布对植被-土壤系统的影响,土壤生物空间异质性的作用,其中包括土壤生物空间异质性与多样性的关系、土壤生物对局部干扰的响应、土壤生物空间格局对植被的影响。

STUDY ON SPATIAL SOIL ECOLOGY BASED ON SPATIAL HETEROGENEITY ANALYSIS OF SOIL ORGANISMS

The composition and structure of biotic communities in soil at one hierarchical level can influence the spatial heterogeneity of the biota at other hierarchical levels. Furthermore, there is increasing evidence that spatial soil ecology can yield new insights with regard to understanding the factors that maintain and regulate soil biodiversity, as well as how the spatial distributions of soil organisms influence both plant growth and plant community structure. In this paper, the role of soil biota in the soil ecosystem in processes was assessed, and the relationship between soil organisms spatial heterogeneity and ecosystem function was presented.
