Embodiment 1

[0055] See figure 2 A flow chart of a crop climate risk recognition method provided by the embodiment of the present disclosure. Such as figure 2 As shown, the crop climate risk recognition method mainly includes the following steps:

[0056] S201, obtains climate index data and crop disaster damage data, generating climate risk census data matrix, wherein each climate index data in the climate risk census data matrix is ​​associated with a crop disaster loss, the crop disaster data Loss data determined according to the disaster damage target;

[0057] Specifically, climate indicators data and crop disaster reduction data can be obtained from the historical data recorded by the meteorological observatory, or you can find a large quantity in the Internet database, and you can find it in the previous record literature.

[0058] In a specific embodiment, the location, time, crop disaster loss data, and multiple climate index data are acquired, and the above data is made into a tabl...

specific Embodiment approach

[0112] According to a specific embodiment of the present disclosure, the method further comprises:

[0113] Calculate the correlation coefficient of all climate risk factors and disaster damage targets in turn;

[0114] By verifying the correlation coefficient, correlation test reliability is obtained.

[0115] Specifically, crop yield can be obtained from the historical data recorded by the weather observation station, or you can find a large number in the Internet database, and you can find it in the previous record literature.

[0116] The crop yield change trend and the correlation coefficient of all single climate index data matrices were calculated using mathematical methods to determine the linear correlation between crop yield change and all single climate index data matrices.

[0117] In a specific embodiment, the T test is used to verify all related coefficients, resulting in correlation inspection reliability, and investigating the consistency of the correlation coeffic...

Embodiment 2

[0131] See Figure 4 The block diagram of a crop climate risk recognition device provided in the present disclosure embodiment. Such as Figure 4 As shown, the crop climate risk recognition device 400 includes:

[0132] The module 401 is acquired to obtain climate index data and crop disaster damage data, generating climate risk census data matrix, wherein each climate index data in the climate risk census data matrix is ​​associated with a crop disaster loss data, said Crop damage data is the loss data determined according to the disaster damage target;

[0133] The sort module 402 is used to rearrange the climate index data in order to increase or decrease in each climate index data, to obtain a single climate index data matrix, wherein the single climate index data matrix includes all climate indicators corresponding to the climate index. And crop disaster data;

[0134] The determination module 403 is used to determine whether the climate index is a primary selection climate r...

Abstract

The embodiment of the invention discloses a crop climate risk identification method and device and computer equipment, and relates to the technical field of risk assessment, and the method comprises the steps: obtaining climate index data and crop disaster data, and generating a climate risk general survey data matrix; rearranging the climate index data according to the ascending or descending sequence of each piece of climate index data to obtain a single climate index data matrix; according to the single climate index data matrix, judging whether the climate index is a primary climate risk index or not by adopting a given technical method; and carrying out independence test on all the primarily selected climate risk indexes by adopting a given analysis method to obtain climate risk factors. The technical scheme provided by the invention is extremely easy to realize through a computer program, passes actual measurement and inspection, has universality, objectively and quantitatively obtains a result, and is convenient for further manual analysis.

Description

Technical field [0001] The present invention relates to the field of risk assessment, and more particularly to a crop climate risk recognition method, apparatus, and computer equipment. Background technique [0002] The content of risk assessment is mainly risk analysis and risk assessment, and risk assessment is based on risk analysis. The basic work of risk analysis is risk identification. The latest risk expressions given by the United Nations Intergovernmental Climate Change Table Committee are: risk = disaster event X exposure x fragility. It can be seen that the key to risk recognition is to identify the disaster factors and vulnerabilities of the target. [0003] At present, the main methods of risk identification have historical experience, analysis methods, knowledge or feelings. Among them, historical experience, knowledge or feels have macroscopic and non-moped. Other risk recognition methods have no versatility, an objective recognition method of operability. Inventi...
