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
