Agrometeorological disasters
Disasters caused to agriculture by adverse meteorological conditions
[QX/T292-2015, definition 3.5]
Agrometeorological disaster risk
The possibility of occurrence of agricultural meteorological disaster events and the possibility of causing agricultural output loss, quality reduction and ultimate economic loss. This standard was drafted in accordance with the rules given in GB/T1.1-2009.
This standard was proposed and managed by the National Agricultural Meteorological Standardization Technical Committee (SAC/TC539). Drafting unit of this standard: Shaanxi Agricultural Remote Sensing and Economic Crop Meteorological Service Center. The main drafters of this standard: Wang Jinghong, Bai Qinfeng, Liang Yi, Gao Maosheng. China is a large agricultural country. Affected by geography and climate, agricultural meteorological disasters occur frequently and with great intensity, and the losses caused by them account for the largest proportion of agricultural natural disaster losses. Agricultural meteorological disaster risk zoning is of great significance to optimizing the layout of agricultural industries and guiding agricultural disaster prevention and mitigation. This standard is formulated to standardize the technical methods of agricultural meteorological disaster risk zoning.
This standard specifies the zoning process, data collection and processing, risk assessment and risk zoning of agricultural meteorological disaster risk zoning. This standard is applicable to the meteorological disaster risk zoning of major crops (including food crops, forestry and fruit, flowers, etc.).

4.2 Data collection
4.2.1 Meteorological data
YTKA-JouaKAa
It is advisable to collect data on agricultural meteorological disasters and their hazard factors at different time scales of 30 years or more. Common agricultural meteorological disasters and their main disaster-causing factors are shown in Table A.1 of Appendix A. 4.2.2 Socio-economic data
It is advisable to collect the latest socio-economic data of each county or township within the zoning area. The socio-economic data required for the risk analysis of common agricultural meteorological disasters is shown in Table A.2 of Appendix A.
4.2.3 Disaster data
It is advisable to collect meteorological disaster data of the corresponding year with the meteorological data, including the affected area of ​​crops, the area of ​​disaster, the area of ​​crop failure, direct economic losses, etc.
4.2.4 Geographic information data
It is advisable to collect digital elevation model (DEM) raster data with a resolution of not less than 1:250000 and loss data such as administrative boundaries and river systems.
4.3 Data processing
The various indices obtained from data processing of different properties and dimensions should be normalized. For the normalization method, please refer to Appendix B.
5 Risk assessment
Risk assessment indicators
5.1.1 Hazard factor risk index
For the classification of disaster factors, it is advisable to refer to the classification method of agricultural meteorological disasters in QX/T392-2017, and classify them into 3 to 5 levels
For the calculation method of the disaster factor risk index, please refer to Appendix C C.1.5.1.2 Exposure index of disaster-prone bodies
It is advisable to use the yield or area of ​​crops in each county or township within the zoning range to characterize the exposure of the disaster-prone body. For the calculation method of the exposure index of the disaster-bearing body, please refer to C.2 of Appendix C. 5.1.3 Environmental vulnerability index
It is advisable to calculate the environmental vulnerability index of agricultural meteorological disasters based on certain mathematical methods and theoretical basis, taking into account the impact of the environment on the formation of disasters, terrain, elevation, water system distribution, etc. For the calculation method of the environmental vulnerability index, please refer to C.3 of Appendix C. 5.1.4 Disaster prevention and mitigation capacity index
It is advisable to use the per capita disposable income, agricultural investment, total agricultural output, etc. of each county or township within the zoning range, based on certain mathematical methods and 4
