研究了荔波喀斯特森林不同演替阶段群落的辐射能特征，揭示了辐射与群落环境的关系。结果表明：总辐射、直接辐射、散射辐射和反射辐射有随群落的进展演替减小之趋势，各辐射分量的日变程呈单峰曲线，日变幅随进展演替减小；同一群落内辐射随高度升高而增大；演替早期群落的光照强度大于演替中及后期群落的光照强度。
The characteristics of radiation energy in different succession stages of Libo Karst forest were studied, and the relationship between radiation and community environment was revealed. The results show that the total radiation, direct radiation, scattered radiation and reflected radiation have a decreasing tendency with the progress of the community. The daily variation of each radiation component shows a single peak curve, and the daily variation amplitude decreases with the progress of the community. The internal radiation increased with the height increasing. The light intensity of the early succession community was greater than the light intensity of the succession and the later community.
