Abstract

The invention belongs to the field of agriculture and water resource development and utilization, and discloses an agricultural drought disaster monitoring and forecasting method based on crop water demand and soil water supply, which comprises a crop water demand information acquisition module, a soil water supply information acquisition module, a data center, a meteorological forecasting module,a drought forecasting module and a drought analysis module. According to the method, through crop water shortage index calculation and crop water profit and loss prediction calculation in future predetermined time in different regions, the water shortage condition of crops can be comprehensively evaluated, and a reliable data basis is provided for analysis and evaluation of drought conditions. According to the invention, a meteorological system and a crop water requirement law are combined for development, including agricultural drought comprehensive prediction, monitoring, scientific assessment and early warning, so that water resources can be reasonably allocated to cope with drought, and the method has very important theoretical and practical significance for solving the drought and promoting crop growth.

Description

technical field

[0001] The invention belongs to the fields of agriculture and water resource development and utilization, and in particular relates to an agricultural drought disaster monitoring and forecasting method based on crop water demand and soil water supply. Background technique

[0002] At present, the existing technologies commonly used in the industry are as follows: my country is a large agricultural country, and the huge population base forms a rigid constraint on the food requirements. However, my country's special geographical features and regional climate make agriculture face many natural disasters. Drought is one of the main natural disasters affecting my country's agricultural production, and the annual grain loss due to drought accounts for half of the total grain loss in the country due to disasters. This is due to the fact that the majority of farmers have always had the idea of ​​relying on the weather for food. On the other hand, the decision-making...
