Abstract: Chlorophyll is an important pigment of turf color and it is an intrinsic factor for turf quality evaluation. The relationship between spectral properties of two turf communities and their chlorophyll contents were measured using reflectance spectroscopy with natural illumination. Results were analyzed by the partial least squares method. The model of chlorophyll content used reflectance spectroscopy in the range of 400-700 nm and gave a correlation coefficient between estimated values and real values of 0.937, with a relative standard deviation of 3.2%. A linear model of the partial least squares method with turf color was developed with a smaller RMSE (RMSE=0.26). Reflectance spectroscopy provides a new method for rapid turf quality evaluation in landscape engineering.
