Abstract Solar radiation transmission plays is an important process in the energy exchange in forest ecosystem. There are a lot of transmission models developed for a single canopy, but relatively fewer models for studying spatial distribution of radiation below the forest canopy. In this paper, we used a simple model that was related to canopy cover to calculate the solar radiation below the forest canopy. At the same time, the hemispherical photography integrated with airborne LiDAR to provide a data for the model. Especially, LiDAR data was used to obtain the spatial distribution of the canopy cover. We obtained a spatial distribution of solar radiation below the Qinghai Spruce forest canopy in Qilian Mountains. Results showed that modeled average daily total radiation below the canopy was 21.614 MJ/m2d, ranging from 4.618 to 54.053 MJ/m2d in our experimental zone.
