Study on Characteristics of the Rainfall and Runoff in Tropical Rain Forest of Jianfengling,Hainan
According to rainfall and runoff data of the local observation in tropical rain forest of Jianfengling, Hainan, runoff characteristics in original tropical mountain rain forest, secondary tropical mountain rain forest and lowland rain forest were analyzed. [Result] Forest zone could effectively reduce flood peak in rain season and regulate runoff in arid season, having good flood-regulation and drought-supplementation function. Forest zone impounded 11 660 - 18 031 m per hectare in rain season, and it was secondary tropical mountain rain forest > original tropical mountain rain forest > lowland rain forest. In arid season, drought-supplementation amounts per hectare of the secondary tropical mountain rain forest and original mountain rain forest were respectively 976. 6 and 946. 8 m . Drought-supplementation function of the lowland rain forest was not obvious in arid season. [ Conclusion] The research verified the hypothesis of tropical rain forest having flood-regulation and drought - supplementation function.
