摘要:

植物热值是衡量第一性生产力水平的重要指标。首先,综述了国内外植物热值的研究概况以及所取得的主要成果,包括:植物热值在各群落、科间、种间、无性系、器官等不同层次上的差异,以及凋落物和薪材等热值的研究;热值随季节、年龄和群落演替过程等时间尺度以及经纬度、海拔等空间尺度的变化规律。其次,总结了影响植物热值的因素,包括含碳量、灰分含量以及有机质的含量等内在因素和自然环境、栽种方式、管理措施以及贮藏方式等外在因素。最后,对当前植物热值研究的不足及未来进行了展望与相关讨论。

关键词: 植物热值, 灰分含量, 时空变异, 影响因素, 发展趋势

Abstract:

Calorific value of plants is an important index to measure the level of primary productivity.Firstly,the main achievements of domestic and foreign studies on calorific values of plants were reviewed,including:variation of calorific values of plants at different levels such as communities,families,species,clones and organs,and calorific values of litters and fuelwoods;difference of calorific values of plants on time scale such as season,age and community succession,and on space scale such as latitude,longitude and altitude.Secondly,the factors affecting calorific values of plants were summarized,including internal factors such as carbon content,ash content and organic matter content,and external factors such as natural environment,planting method,management measures and storage method.Finally,the limitations of previous studies on plant calorific values and the trends of future development were discussed.

Key words: plant calorific value, ash content, spatial and temporal variation, impact factor, development trend
