Fruit industry low temperature frost damage risk acquiring method

Abstract

The invention discloses a fruit industry low temperature frost damage risk acquiring method. The method mainly comprises the steps that a data collector acquires the temperature data and the geographic information data of a specific forest fruit planting area, and sends the data to the receiving platform of each place through a wireless data transmission module for storing; the receiving platform of each place sends the received data to the GIS server of a data application central apparatus room; a server GIS database carries out processing to acquire disaster-inducing factor risk index data, hazard-affected body vulnerability index data and disaster resistance and alleviation index data; according to the spatial distribution data of the disaster-inducing factor risk index data, the spatial distribution data of the hazard-affected body vulnerability index data and the spatial distribution data of the disaster resistance and alleviation ability index data, a low temperature frost damage comprehensive risk assessment model is established; and fruit industry low temperature frost damage risk division is carried out. The defects of unreasonable design, incomprehensive comprehensive consideration factor and inaccurate risk early warning of the fruit industry low temperature frost damage risk acquiring method in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of low-temperature freezing injury risk prevention in the forestry and fruit industry, in particular to a method for acquiring low-temperature freezing injury risk in the forestry and fruit industry. Background technique [0002] The natural phenomenon of low-temperature freezing damage has caused huge losses to the forestry and fruit industry. In the existing technology, the defense against low-temperature freezing damage is often an afterthought. Because the existing technology has not proposed a feasible risk warning plan, preventive measures are taken early to give People's economic interests have caused great losses. At the same time, the method of risk acquisition in the existing technology is unreasonable in design, and the factors considered are not comprehensive, resulting in inaccurate risk early warning. Contents of the invention [0003] The purpose of the present invention is to, in view of ...
