本文主要介绍了桉树人工林养分循环的意义与研究现状。从地球化学循环和生物小循环(养分含量、养分积累和分布、凋落物、养分循环特征)两方面阐述桉树人工林养分循环的研究内容，分析说明桉树人工林养分循环研究存在的问题及发展趋势，并提出几点建议。%This paper introduced the significance and research situation of the nutrient cycling in eucalypt plantations. Then, the main researches were introduced from two aspects:geochemical cycles and biological small cycles, i.e. nutrient content, accumulation and distribution of nutrient element, forest litter and the character of nutrient cycling. The problems and prospects in research were summarized, and from these some suggestions were made for future research directions and priorities.
