Research Progress of Soil Moisture Dynamics Models Based on Biomass
摘要
Abstract
Soil moisture is the requirement for crop growth, its content is a basic parameter for predicting crop yield, and its content and spatial distribution can be used to effectively reflect the growing status of crops. Remote sensing means are usually used to monitor soil moisture content in the real time, dynamic and large-area ways. With the development of soil moisture dynamics, one direction of monitoring soil moisture content is to develop a model without relying on the observed data so as to monitor soil moisture content at large scale. First of all, this paper summarizes the effect of soil moisture content on the distribution of crop biomass. Secondly, some main soil moisture dynamics models are reviewed based on emphasizing their advantages and disadvantages. Finally, a suggestion of improving the dynamics model is proposed by using RS data based on the relationship between soil moisture content and crop biomass. The developing trend of soil moisture dynamics is discussed so as to promote the study of retrieving soil moisture content using biomass.关键词
