Abstract: [Objective] This paper presents a systematical review of the progress in studies of ecological stoichiometry in terrestrial ecosystem, which plays an important role in further understanding the material circulation and energy flow of terrestrial ecosystem.[Method]The databases of Web of Science, CNKI and others were used to summarize the progress in ecological stoichiometry in terrestrial ecosystems by consulting relevant literature.[Result]The study of ecological stoichiometry of terrestrial vegetation showed that C, N and P were the main objects in the field of ecological stoichiometry, of which N and P were the two most important limiting elements for the growth of terrestrial vegetation. The study of ecological stoichiometric characteristics of land soil showed that the ratio of carbon, nitrogen and phosphorus in soil was an important indicator for evaluating soil quality, and it was found that the ratio of carbon to nitrogen to phosphorus in soil was basically constant at the global scale. The study of nutrient limitation in terrestrial ecosystems showed that N:P was a sensitive indicator of plant growth nutrient constraints, and was often used to determine the threshold of nutrient limitation. Meanwhile, the content of N and P can also be used to determine the type of nutrient restriction. Climate, geography, soil and other factors were the main factors affecting the ecological stoichiometry characteristics of terrestrial plants.[Conclusion]In the studies of ecological stoichiometry of terrestrial ecosystem, C, N and P are important factors that scholars pay attention to and their ratio plays an important role in the evaluation of soil quality and nutrient limitation threshold.
