【摘要】：群落结构如何响应环境变化是生态学研究长期关注的核心问题之一。粒径谱由个体大小和多度构建而来,与营养级转换速率相关、反映生态系统过程动态以及表征生态系统稳定性,可以将其视为一个综合的功能多样性指标用于预测和表征群落的组成以及生态系统功能如何响应环境压力。粒径谱研究最初始于水生生态系统,近年来被引入到土壤动物群落生态学的研究中。简要回顾粒径谱的概念由来及理论基础,分析比较了当前粒径谱研究中的4种易混淆类型,介绍了常用的两类土壤动物粒径谱构建方法及其生态学意义,梳理了土壤动物粒径谱对环境梯度响应与生态化学计量学相结合的研究进展,并指出了应用粒径谱研究土壤动物群落的难点及限制条件。未来,在基础理论研究方面,土壤动物粒径谱应关注个体大小与营养级位置及能量利用关系;在应用方面,土壤动物粒径谱可结合传统的分类方法广泛应用于指示环境污染、生态恢复、保育生物以及土地利用变化等。
[Abstract]:How community structure responds to environmental changes is one of the core issues in ecological research for a long time. The particle size spectrum is constructed from individual size and abundance, which is related to the rate of nutrient conversion, which reflects the dynamics of ecosystem processes and represents ecosystem stability. It can be regarded as a comprehensive functional diversity index to predict and characterize the composition of communities and how ecosystem functions respond to environmental pressures. Particle size spectrum (PSD) was first studied in aquatic ecosystem and introduced into soil fauna community ecology in recent years. This paper briefly reviews the origin and theoretical basis of particle size spectrum, analyzes and compares four confusing types of particle size spectrum, and introduces two commonly used methods for constructing particle size spectrum of soil animals and its ecological significance. The research progress of soil animal particle size spectrum combined with environmental gradient and ecochemometrics was reviewed, and the difficulties and limitation conditions of soil animal community were pointed out. In the future, in basic theoretical research, the particle size spectrum of soil animals should pay attention to the relationship between individual size, nutritional position and energy utilization. In application, soil animal particle size spectrum can be widely used to indicate environmental pollution in combination with traditional classification methods. Ecological restoration, conservation of organisms and land use change, etc.
