摘    要:生态化学计量学已成为生态学研究的热点问题。作为一门新兴学科,综观国内外最新研究进展,相关研究目前尚存在着许多不足。基于此,从全球与区域尺度、功能群尺度及个体水平3个方面阐述生态化学计量学特征,从空间、时间、生境和植物类型等生物与非生物因素综述生态化学计量学特征的驱动因素。并讨论生态化学计量学特征在限制性养分判断、生态系统稳定性、生长率与C:N:P关系中的应用。

关 键 词:生态化学计量学  限制性养分  内稳性  C:N:P

Abstract:It is necessary to construct a unified theoretical framework of ecology in view of the rapid developments in modern ecology.Eological stoichiometry is the discipline to study the balance between multiple chemical elements in ecological processes, and unify the research of different levels.Ecological stoichiometry is a theory, a thinking way and a tool that should permeate all aspects of ecology.Currently, studies on ecological stoichiometry are relatively few in China as compared to elsewhere.Studies mainly focus on the C, N, P ecological stoichiometric characteristics and its driving factors, especially in forest and grassland ecosystems.Ecological stoichiometric characteristics in different regions and ecosystem types were different, but at relatively smaller scale, the differences were less.Compared with the other parts of the world, terrestrial ecosystem phosphorus deficiency in China appeared higher for C:P and N:P ratios.Ecological stoichiometry characteristics on the level of functional group appeared that herbaceous N:P was smaller than that of wood.The mode of living plant, litter and soil showed that litter ecological stoichiometry was similar to living plant and the soil ecological stoichiometry was changed with the order of soil.Ecological stoichiometry characteristics on the level of individual showed that the correlation of plant leaves, stem and root ecological stoichiometry that appeared variable as the plant grows.Seen from the environmental factors that influenced the ecological stoichiometry, contain latitude, hydrothermal conditions, pedogenesis, human disturbance etc.Ecological stoichiometry had been applied on many areas of ecology and biology.For example, N:P stoichiometry was one of the most important indicators of limited nutrient conditions, but the criterion of the indication of ecological stoichiometry in various ecosystem were different, and it was necessary to further clarify its applicability.Second, use the ecological stoichiometric homeostasis to clarify the effect of environmental change on ecosystem structure, function and stability, which varied with the change of nutrient availability, fertilization, species and growth stage.Third, taken the C:N:P as the most import index of the plant growth rate, relationship between growth rate and C:N:P was proposed based on the growth rate hypothesis, and then linked cell and genetics with growth rate.Seen from the newest research advance, the relative research was fewer for the new subject.For the reason, the ecological stoichiometry characteristics is clarified on global and regional scale, group scale and individual scale.In order to deepen the understanding of ecological stoichiometry characteristics and its driving factors, quantitatively assess limited nutrient and homeostasis of ecological stoichiometry in ecosystems, forecast community, ecosystem structure and stability evolution trend, strengthen the understanding of relationship between growth rate and ecological stoichiometry characteristics, the newest research advance was reviewed.This is consistent with the controlling factors including biotic and abiotic factorsat spatial and temporal scales, habitat and plant types.At the same time, application of ecological stoichiometry characteristic on limited nutrient, ecosystem homeostasis and the relation between growth rate and C:N:P variation are discussed.It will be necessary for achieving optimal management of ecosystems and their reasonable protection, maintaining the regional ecological security and sustainable development.
