现 General flood: The reappearance period is less than 10 years.

重 Large flood: The reappearance period is 10-20 years.

现 Da flood: The reproducible period is 20-50 years.

重 Great flood: The reproduction period is more than 50 years.

It is estimated that the hydrological factor items of the reproduction period include the flooding water level (flow) or the maximum flood period, etc., which can be selected according to the hydrological characteristics of the river (river section).

03

drought

Refers to the damage caused by drought on agricultural production, urban and rural economy, residents' lives and ecological environment. It is mainly manifested in drinking water due to drought and droughts caused by drought.

04

Drought

3

Planting tree afforestation, improving regional climate, reducing evaporation, and reducing the dangers of drought wind;

4

Study and apply modern technology and water -saving measures, such as artificial rainfall, drip irrigation, ground film coverage, and temporary use of poor water sources, including poor groundwater and seawater.
