Agricultural drought warning and forecasting monitoring device and method

Abstract

The invention provides an agricultural drought warning and forecasting monitoring device. The device comprises a real-time soil moisture status data acquisition module, a drought condition evaluation module, an information releasing module, a database and a medium-long term weather forecast interface. The invention further provides an agricultural drought warning and monitoring method based on the device. Water surplus and deficit conditions of crops in different regions within next preset time are forecasted according to soil moisture status information acquired in real time in different regions and by combining precipitation and temperature information, within the next preset time, provided by a third party, and drought region division is performed based on the water surplus and deficit conditions of the crops. Thus, droughts can be discovered timely beneficially for the convenience of reasonably allocating water resources so as to cope with disasters. Comprehensive monitoring, scientific evaluation and warning of the droughts are realized, and the device and the method are of great theoretical and practical significances for solving the problem of loss caused by agricultural droughts or floods.

Description

technical field [0001] The invention relates to the fields of agriculture and water resources development and utilization, in particular to an agricultural drought early warning and forecasting monitoring device and method. Background technique [0002] my country is a large agricultural country, and the huge population base forms a rigid constraint on the demand for food. However, my country's special geographical features and regional climate make agriculture face many natural disasters. Drought is one of the main natural disasters that affect 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. On the one hand, farmers have always had the idea of ​​"depending on the weather for food". On the other hand, the decision-making department lacks due real-time moisture and rainfall analysis information, and cannot timely carry out early warning of agricultural drought. [0003]...

AI Technical Summary

Problems solved by technology

On the one hand, this is because the majority of farmers have always had the idea of ​​"depending on the weather", on the other hand, because the decision-making department lacks due real-time moisture and rain analysis information, and cannot carry out early warning of agricultural drought in time

[0003] In the face of the widespread and frequent occurrence of global drought and flood events, the reality of frequent droughts and rapidly aggravating impacts in my country has become a major obstacle to economic and social development and ecological environmental protection. At present, my country's domestic agricultural drought monitoring The early warning system is based on the soil water content, and there is basically no systematic combination of the meteorological system and the law of agricultural water demand to carry out comprehensive monitoring, evaluation and early warning of agricultural drought.

Even in the monitoring of agricultural drought, it is currently mainly focused on the monitoring of soil moisture stations, and there is no systematic analysis based on the objective scientific fact of whether the crops are really short of water, and there is no research combined with weather forecasting.
