| 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. |
