Climate, biophysical conditions and human activities all contribute to the occurrences of ecosystem and environment problems, i.e. water scarcity, desertification, salinization, in arid and semiarid zone of North China. Mongolian Scots pine tree (Pinus sylvestris var. mongolica) is one of the principal species of the windbreak and sand-fixing forest in this area. In this paper, we presented the calibration...
R/FR (red to far-red ratio) is a key light signal for plants to detect the oncoming competition and initiate the shade avoidance syndrome. This study is aim to simulate the R/FR signal received by maize plants based on a 3D canopy radiative model. Optical properties of maize leaf were characterized by an adapted Cook-Torrance model for reflectance and a Lambert model for transmittance. Virtual maize...
