Principles and methods of grassland yield estimation by using remote sensing technology

Based on the introduction of principles and methods for grassland yield estimation through remote sensing, the features and existing problems of different methods for dynamic monitoring of grassland such as RS model and the combination of RS and Geo models were analyzed. With the development of remote sensing technology, the grassland yield estimation technology and methodology will be continuously developed, the grassland yield estimation model which is based on the remote sensing technology and methodology will be more reliable, its application will be extended to more areas such as the monitoring of grassland ecosystem, grassland degradation and grassland vegetation growth.
