Smart irrigation and drainage decision method and system for irrigated area rice field based on remote sensing data inversion

Abstract

The invention relates to a smart irrigation and drainage decision method and system for an irrigated area rice field based on remote sensing data inversion. The method comprises the steps of S1, obtaining remote sensing data; S2, carrying out inversion on the remote sensing data and carrying out inversion and extraction on element information based on obtained multi-source remote sensing data products; and S3, carrying out irrigation and drainage decision analysis. The system comprises a remote sensing data obtaining module, a remote sensing data inversion module and an irrigation and drainage decision analysis module for forming the irrigation and drainage decision of the irrigated area rice field. According to the method and the system, precise water level control can be carried out on the irrigated area rice field; the irrigation and drainage water quantity is precise; the non-point source pollution runoff is minimized; the water-saving precise water level control is carried out on the irrigated area rice field; the problem that irrigated area resources are wasted, irrigation and drainage are not in time and the non-point source pollution runoff of an irrigated area is serious can be solved; and moreover, the method and the system have relatively good expansibility and relatively high economic benefit and social benefit.

Description

【Technical field】 [0001] The present invention relates to an intelligent irrigation and drainage decision-making method and system for paddy fields in irrigation areas based on inversion of remote sensing data, and in particular to an intelligent irrigation and drainage decision-making method that utilizes inversion of remote sensing data to realize precise control of water levels in paddy fields in irrigated areas and reduce the loss of agricultural non-point source pollution in paddy fields in irrigated areas methods and systems. The method belongs to the technical field of non-point source pollution prevention and control. 【Background technique】 [0002] Rice is one of the main grain crops in China, accounting for about 40% of the total grain output. Due to the physiological characteristics of rice, a large amount of irrigation water is required throughout the growth stage. Paddy fields consume a lot of water, but their water use efficiency is low. According to statist...
