Disasters
Causes
Time and space distribution
Hazard
Defence measures
Typhoon
Cyclones strongly developing in tropical or subtropical oceans
The annual summer fall festival affects the provinces of guangdong, hainan, fujian, zhejiang and taiwan on the south-east coast of the country
Hurricanes, storms and storm surges have caused enormous economic losses and loss of life for people in coastal areas
1 enhanced monitoring and forecasting
2 timely release of typhoon forecasts and alerts
Construction of coastal protected forests
Heavy rains and floods
A continuous or short-term storm
This is mainly in the south and east. Spring in the pearl river basin, summer autumn in the gangay region and north
Inundation of factories and agricultural lands, resulting in reduced crop yields; affecting transport; and even endangering human life
1. Monitoring of heavy rains using meteorological satellites
2 increase in the accuracy of storm forecasting
3 combined engineering and non-engineering measures
Drought
Long periods of no or abnormally low precipitation, resulting in dry air and water scarcity in the soil
In north china, there's so much drought, so much drought in the middle and lower parts of the yangtze river
Reduced production of food and poor drinking water for humans and animals, affecting economic development and social stability
1. Changing agricultural structures
2. Cultivation of drought resistant crops
3 implementation of agricultural water infrastructure
4 construction of protected forests
Cold tide
Large-scale severe cooling caused by rapid invasion of cold air, accompanied by wind, rain and snow, freezing, etc
Mostly in the middle of the winter, from northeast to southeast
Heavy winds and cooling weather have caused the freezing of crops and livestock, affecting transport, communications and buildings
Issue accurate cold news or early warning to prepare for cold
Earthquakes, landslides, mudslides
Complex geological formations, rugged terrain, irrational human activities, etc
South-west
Human and animal casualties, heavy damage to property and serious damage to public facilities
Awareness-raising on disaster prevention and mitigation, reinforcement of buildings and rock bodies, and avoidance of hazardous areas
