摘　　要：生态化学计量学主要是研究碳、氮、磷等元素在各种生态过程中平衡的一门科学,其核心问题是揭示生物体元素组成的差异对生态功能的影响。由于生态化学计量学研究可以把生态实体的各个层次在元素水平上统一起来,因此生态化学计量学已成为许多生态系统的新兴研究工具。目前,生态化学计量学的研究与应用已深入到生态学的各个层次(分子、细胞、个体、种群、群落、生态系统及区域等不同尺度)。该文围绕生态化学计量学的两个重要组成理论,并结合笔者近年来的研究,归纳总结了生态化学计量学在水生态系统中的研究与应用及未来研究重点,希望有助于推动我国生态化学计量学在水生态系统中的应用研究。Ecological stoichiometry studies the balance between multiple chemical elements in ecological processes.It is a theory,a way of thinking and a tool.The key problem for ecological stoichiometry is to reveal the effects of variations in the elemental composition of organisms in regards to ecological functions.Ecological stoichiometry can permeate all aspects of ecology because it can unify all ecological processes（from molecules to the biosphere）.Key principles（homeostasis and growth rate hypothesis）of ecological stoichiometry are based upon elemental stoichiometry which is the core of ecological stoichiometry.Combined with our own research,we reviewed a number of new achievements in ecological stoichiometry in aquatic ecosystems.This review will help advance studies and applications of ecological stoichiometry in aquatic ecosystems in China.
