摘要: Spectral indices from remotely sensed data, such as the Normalized Difference Vegetation Index (NDVI), are often used to estimate biophysical characteristics of vegetation. The objective this study is evaluate effect senescent leaves on estimation fraction photosynthetically active radiation absorbed by green elements canopy (fAPAR g ) NDVI measurements. An experiment was conducted under controlled conditions over grass canopies. Both and fAPAR were measured when cover changed. results demonstrated that significant values. A similar observed In these conditions, simple models developed relate values fractions vary. When combining models, a linear relationship found between , which in good agreement with our experimental observations. Complement...
