Abstract

The invention discloses a remote sensing quantitative inversion method for soil moisture supply amount. The method comprises the integration of dynamic simulation of crop growth, remote sensing quantitative inversion, soil moisture balance and kinetic equation so as to obtain the soil moisture supply amount from a certain time interval to the entire growth period of a crop growth period. The characteristics of dynamic simulation technology and remote sensing quantitative inversion technology for crop moisture stress information are integrated, so that real-time and dynamic monitoring of the soil moisture supply amount in the crop growth period is realized. The largest advantage of the method is that the monitoring of the soil moisture supply amount is dynamic in the aspect of time and continuous in the aspect of space.

Description

technical field [0001] The invention relates to a remote sensing quantitative inversion method for soil water supply in the whole growth period of crops, which uses crop growth dynamic simulation technology and remote sensing quantitative inversion technology to perform dynamic monitoring of crop water stress information closely related to the field of agricultural production. Background technique [0002] Soil moisture is closely related to crop growth. The traditional monitoring method of soil moisture and crop moisture is to measure the soil moisture content at different levels by ground field observation, and then obtain the soil moisture supply and crop water stress information in a certain period by calculation. . Crop growth dynamic simulation technology is a model that simulates crop yield, water and fertilizer balance, and physiological, biochemical and structural parameters during crop growth and development based on meteorological conditions, soil conditions, crop...
