| 摘 要： | 森林土壤养分的空间异质性直接关系着林地生产力、生态恢复的方向与途径，是植物群落空间格局形成的重要影响因素，对生态系统的演替有重要作用，因此近年来有关土壤养分空间异质性的研究成为国内外研究的热点。文中就海拔高度、土层深度、坡向、植被类型等环境因素对森林土壤养分空间异质性的影响进行了综述，指出目前该研究领域存在的主要问题是结合多种环境因子对土壤进行季节动态变化的研究比较缺乏，基于林分或更大尺度下对森林生态系统土壤空间异质性的形成机制、土壤空间变异规律同人为干扰、物种空间分布格局等关系的研究应该得到更多重视，并提出今后研究的方向。

| Abstract: | Spatial heterogeneity of soil nutrients in forest, directly related to forest productivity and the orientation and approaches of ecological restoration, is an important factor in plant community spatial pattern formation and plays a very important role in ecosystem succession process, so in recent years the research about soil nutrients spatial heterogeneity become a hot issue. The paper discussed the impacts of altitude, soil depth, slope and vegetation type on spatial heterogeneity of soil nutrient, and pointed out that the problems and shortcomings in the research are few research carried out on seasonal dynamics of soil under combination of environmental factors. The research about the relationship between the formation mechanism and spatial patterns of soil spatial heterogeneity of forest ecosystems at stand or larger scale, anthropogenic interference and species spatial distribution pattern deserve more attention. And the directions of future research were proposed. |
