摘要:

荒漠生态系统是中国陆地生态系统的重要组成部分,具有独特的结构和功能。生态化学计量学重点关注C、N、P元素比例及权衡关系,已成为揭示生态系统养分循环及其限制等生态过程的有力工具。植物自身体现出对养分元素的调控能力和对环境变化的响应及适应性,土壤C∶N∶P可表征土壤养分供应能力和储量变化,植物-土壤系统中N、P的养分循环关系密切。从植物营养器官元素化学计量,区域尺度荒漠植物与土壤化学计量特征及其影响因子,化学计量平衡(C∶N∶P)在个体发育、种群动态和群落结构形成过程中的作用,以及植物-土壤系统生态化学计量学的相互关系等角度,论述近10年来中国荒漠生态系统生态化学计量学研究进展,并就今后研究内容进行展望。

Abstract:

Desert ecosystem is an essential part of the terrestrial ecosystem in China, with a unique structure and function. Ecological stoichiometry focuses on the ratio of C, N, and P chemical elements, and their balance relationships have become a powerful tool for revealing ecological processes such as nutrient cycles and limitations in ecosystems. Plants have the ability to regulate nutrient elements among organs and respond to environmental changes. Soil C∶N∶P characterizes changes in soil nutrient supply capacity and storage. There is also a close relationship between N and P nutrient circulation in plant-soil system. From the perspectives of plant-organ element stoichiometry, plant-soil stoichiometry characteristics and its influencing factors at the regional scale, the role of C∶N∶P stoichiometric balance in the process of ontogeny, population dynamics and community structure formation, and interrelationships of ecological stoichiometry in plant-soil systems, we discussed the research progress of ecological stoichiometry of desert ecosystems in China in the past ten years and looked forward to the future research content.

Key words: desert, ecological stoichiometry, allometric growth, environmental response
