【 摘 要 】

In this study, the hyperspectral measurements of natural meadow grassland plants in Nanshan, Urumqi, and Xinjiang were carried out by using a portable ground object spectrometer. The results showed that the natural vegetation height of Nanshan natural meadow grassland increased in May and June, decreased in July and recovered in August and September. According to the hyperspectral data analysis, the correlation between vegetation height and vegetation height is mainly concentrated in the blue and green bands, and has a strong negative correlation. The correlation between blue light and green light is slightly higher than that between red light and natural height of vegetation. At the same time, we established a relational model based on the correlation between vegetation growth and spectral reflectance.
