草地遥感估产的原理与方法

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

在介绍草地遥感估产的原理和方法的基础上,分析了单纯的遥感模型、遥感模型与地学模型相结合等不同估产方法及草地面积动态监测的特点和存在问题,并对草地遥感估产方法发展趋势做了总结。随着遥感技术的发展,草地遥感估产技术和方法也将继续发展,基于遥感数据和方法的草地估产模型更加趋于成熟,其应用也将向草原生态系统、草地退化监测、草地植被生长监测等领域扩展。

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.
