Agrometeorological disasters
Disasters caused to agriculture by adverse meteorological conditions
[QX/T292-2015, definition 3.5]
Agrometeorological disaster risk

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.).

This standard applies to meteorological disaster risk zoning for major crops (including food crops, forestry, fruit, flowers, etc.). Terms and Definitions The following terms and definitions apply to this document. 2.1 agrometeorological disastersAgrometeorological disasters Disasters caused to agriculture by adverse meteorological conditions [QX/T292—2015, definition 3.5] Agrometeorological disaster risk agrometeorological disaster riskThe possibility of an agrometeorological disaster event and the possibility of causing agricultural output loss, quality reduction and ultimate economic loss. 2.3 Disaster factor Adverse weather and climate factors that lead to the occurrence of agrometeorological disasters. Note 1: Weather factors include sunshine hours, temperature, humidity, wind speed, etc.; climate factors include radiation factors, atmospheric circulation factors, and geographical factors. Note 2: Rewrite QX/T405—2017 definition 3.2. 2.4 Hazard of disaster factor risk of disaster factor The level of variation of the disaster factor and the possibility of its occurrence. 2.5 hazard-affected body hazard-affected body the main body of crops that are subject to agro-meteorological disasters. Note: rewrite GB/T32572-2016, definition 2.2. 2.6 hazard-affected body exposure the scale of the body that may be affected by meteorological disasters 2.7 environmental fragility environmental fragility the possibility that the stability of the agro-ecosystem will be destroyed under the influence of meteorological disasters. 2.8 capabilityofdisasterpreventionandmitigation the ability of risk bearers, with people as the main body, to take certain means or measures to prevent and reduce disaster losses when facing agro-meteorological disasters. 1 YTkAa-cJouaki QX/T527-2019 Yika-JouakA Disaster level indicatordisasterlevelindicatorThe critical threshold of the disaster factor determined according to the degree of damage to crops after the meteorological disaster. 2.10 disasterlossrate Disaster loss rate The percentage of crop yield reduction in the year caused by meteorological disasters. Note: Rewrite QX/T392-2017. Definition 2.6. 2.11 Risk index riskindex A quantitative indicator for assessing the risk of agricultural meteorological disasters based on the risk assessment model. 2.12 Risk zoning risk zoning According to the size of the agricultural meteorological disaster risk index, the spatial distribution of agricultural meteorological disaster risks is divided into regions. 3 Zoning process The agricultural meteorological disaster risk zoning process is shown in Figure 1.

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 YTkAa-cJouaki Tip: This standard content only shows part of the intercepted content of the complete standard.
