摘　　要：生态化学计量学是近年来新兴的一个生态学研究领域,探讨碳、氮、磷生态化学计量学特征,可以更好地揭示生态系统内植物-土壤养分元素相互关系。该文概述了国际上生态化学计量学在植物营养学以及森林生态系统方面的研究;重点综述了国内生态化学计量学在林木营养方面研究现状以及落叶松人工林的主要研究成果;在此基础上,提出了华北落叶松需要进一步研究的科学问题,并对秦岭不同林龄华北落叶松人工林碳、氮、磷生态化学计量学特征研究进行了展望,进而提出华北落叶松人工林碳、氮、磷生态化学计量学进一步研究采取的措施和方法,以期引起国内同行的重视并推动该领域的进一步发展。Ecological Stoichiometry is an emerging ecological research field in recent years.The relationship between soil nutrient element and plant interactions through discussions on the characteristics of C,N,P ecological stoichiometry can be better revealed.The study on ecological stoichiometry of plant nutrition and forest ecosystems internationally were introduced in this paper firstly.Secondly,current situation of ecological stoichiometry in tree nutrient and the main research results of Larix gmelinii in China were emphatically reviewed.Meanwhile,several scientific problems in Larix principis-rupprechtii plantation were advanced,and the research on ecological stoichiometry characteristics of C,N and P in Larix principis-rupprechtii plantation of Qinling Mountains was look ahead.Then the measures and methods to be further taken on the study of ecological stoichiometry characteristics of C,N and P in Larix principis-rupprechtii plantation of Qinling Mountains with an aim to promote this discipline of research in China was put forward.
