热带草地的第一性生产力

Primary Productivity in Tropical Grassland

热带草地是地球陆地植物群落中面积最大，占第一性生产量比例最高的植被类型．本文总结了热带草地第一性生产力的成果，并结合作者本人的研究，对热带草地第一性生产力研究现状及存在问题进行讨论。

Tropical grassland is now the largest terrestrial biome in terms of occupied area. It has been estimated that tropical grassland may store about 26% of the total carbon sequested by terrestrial communities each year. This paper summaries the work of author and other people in primary productivity of tropical grassland ,discusses implication and problems of these results and provides some suggestions for further study.
