摘要/Abstract

摘要： 介绍了热值的定义、表示方法、研究意义和植物热值在生态学中的研究历史与现状；分析了植物热值的时空变异性，包括热值在种间和类群间的变异及热值的种内变异规律；探讨了影响植物热值变化的因子（包括气候、立地条件、胁迫环境和人为干扰等）和热值变异的内在决定因素（包括碳浓度、灰分含量及有机质化学组成等）；对植物热值的研究前景和局限性进行了展望。

Abstract: This paper introduced the definition of caloric value, its representation and significance, and the research advances in plant caloric value, with the spatio-temporal variation of caloric value among and within plant species and groups as well as the factors affecting this variation, including climate, site condition, stress environment, human disturbance, and the intrinsic factors such as carbon concentration, ash content, and chemical composition of organic matter analyzed. The perspectives and limitations on the study of plant caloric value were also discussed.

Key words: Weeping lovegrass, Clipping intensity, R/FR ratio, Tillering
