摘　　要：微生物生态正在受到越来越多的关注,对其研究也渐趋深入。然而由于微生物个体微小的特点及研究手段的限制,多数研究还停留在探索阶段,研究方法也在不断完善当中。近年来,较多的研究开始探讨空间因素在微生物多样性和分布中的影响,对空间分布的探讨有助于更好地认识生态过程,是一种有力的研究手段。微生物空间分析方法已经成为微生物生态学领域中重要的研究方向之一,我国空间方法在微生物生态研究中的应用还没有得到普遍的重视。从不同研究角度出发,结合空间统计的作用,对空间统计方法在微生物生态研究中的应用的必要性及现状做了评述。介绍了空间自相关性的检验,方差图,Mantel检验,Kriging插值等方法在微生物生态研究中的应用,并论述了微生物研究中的尺度问题。这一梳理,对丰富微生物生态学研究中的新方法、新手段具有一定价值。Studies of microbial ecology are receiving increasing attention in the world and are developing very quickly.Nevertheless,due to the limitations of research techniques and special characteristics of microbes,most studies are only at the exploratory stage while the relative methods are also in development.In recent years,considerations of spatial factors have shown a significant trend and many researchers have focused on this area.Many studies have begun to consider the spatial influence of the distribution of microbial communities and significant results had been achieved in this area.Studies on spatial patterns of microbial community can give us a better understanding of ecological processes.However,due to subject barriers and the minuteness of microbes,at present spatial concepts are not receiving adequate attentions in China.This paper focuses on a brief review of the current situation and progress of spatial analysis,and its potential application in microbial ecology.We introduced descriptions of spatial autocorrelation in microbial ecology studies,including Moran＇ I and Geary＇s c,Mantel test and the use of variogram analysis.Kriging was referred to as a tool to predict microbial patterns and the scale of microbial studies were also discussed.This review will be helpful for understanding spatial methods and their application in microbial ecology.
