内容記述 | To understand global climate changes, it is essential to monitor the temporal and spatial distributions of vegetation. Digital cameras are relatively inexpensive to operate and have small labor requirements, allowing the detection of subtle seasonal variation at high spatial resolution. Recent studies have reported that camera-based indices calculated from the digital values of 3 color components are helpful in grasping the seasonal variation of vegetation phenology, such as leaf expansion or fall. To examine this possibility, we investigated seasonal variation characteristics of camera-based indices for alpine plants. Although digital camera values are modified by solar radiation, this dispersion can reduce by using the normalized color component values with their arithmetic mean. We surveyed the relationship between well-known indices (VIgreen and 2G_RBi) and the seasonal variation of five major alpine plant types. The VIgreen index is very useful for the analysis of seasonal changes in alpine plants. | |||||
