What are the natural disasters in the mountains and forests, and ask for some knowledge of the prote

To reduce the impact of drought and floods, we should give priority to prevention, combine resistance with resistance, do a good job in afforestation and soil and water conservation, and carry out river improvement and farmland water conservancy infrastructure.

Prevention of waterlogging disasters: Strengthen monitoring, forecasting and early warning, and establish a sound drainage system.

Flood: The key point of forecasting is the precipitation of the entire river basin including the main stream and tributaries, even if the water level changes are understood, the main content of defense is to strengthen the embankment, evacuate the residents in low-lying areas, establish an emergency plan for flood control, do a good job of possible flood prevention, equip with sufficient food and rescue equipment, prepare for flood discharge in advance, and so on.

Effective measures to fight drought: We will strengthen the education of the whole people's awareness of the water crisis, establish water-saving agriculture, industry and society, implement the drought prevention plan system, establish a drought control information system and a drought resistance material reserve system, and improve the emergency response capacity to drought disasters; We should strengthen the construction of drought-fighting facilities, improve water supply capacity and water resource utilization efficiency, transfer water across river basins, and control the number of people.

Anti-insect measures: pesticide insecticide, introduction of natural enemies, trapping adults or larvae.

Typhoons: Forecasts and early warnings should be made in advance, dams and waterways should be strengthened, gas circuits should be repaired, fishing boats and fish rafts should be reinforced, ships should anchor deeply when entering ports, and coastal shelterbelts and coastal protection should be built.

:*: Raising awareness of disaster prevention and mitigation; support at all levels; appropriate population migration; Aizhong arranges settlements and takes care to avoid fault zones; Mountainous areas should be greened to the maximum extent and maintain a high vegetation coverage rate; For some landslides, debris flows and other geological disasters prone to the area, take engineering treatment; New buildings should be more earthquake-resistant; We should prudently develop the heavy chemical industry and improve the mode of transportation and communications.

For individuals: In case of **, take refuge first, find a gap under the table and bed, lean against the corner of the wall and bend your body, seize the opportunity to escape, stay away from all buildings, and squat in the open ground after the shock.

Forest fires: Everyone should establish the awareness of "forest fire prevention". Establish and improve forest protection and fire prevention organizations and systems.

Carry out publicity and education on forest protection and fire prevention. Strict fire source management. Establish forest fire prevention facilities.

1. Open up fire roads. 2. Create a fireproof forest belt. 3. Build forest roads.

4. Set up a fireproof lookout. ）

Sandstorms: 1We should strengthen the protection of the environment and raise the protection of the environment to the level of the legal system.

2.Restore vegetation and strengthen biocontainment systems to prevent windblown sandstorms. 3.

Formulate plans for disaster prevention, disaster resistance, and disaster relief in accordance with local conditions in different regions, actively promote various disaster reduction technologies, and build a number of demonstration projects to gradually promote them from point to point, so as to further improve the regional comprehensive defense system. 5.Control population growth, reduce the pressure of human factors on the land, and protect the environment.

Cold wave: The key points of the forecast are the high-latitude weather system, the source and southward path of the cold air, the intensity of the cold wave and the time of impact on various places. The defense mainly includes cold protection for crops, covering plastic film, artificial heating, issuing cold wave warnings, reminding residents to pay attention to keeping warm, and preventing the adverse effects of bad weather brought by cold waves on buildings and traffic.

It can be seen from the common natural disaster occurrence map in mountainous areas that it is a collapse, and the way to prevent this natural disaster is to use reinforcement works such as blocking, net packing, excavation and anchoring; It is a landslide, and the way to prevent and control the natural disaster is to excavate a drainage ditch or interception ditch project to reduce the water content of the landslide body; It is a debris flow, and the way to prevent and control this natural disaster is to protect forests, build reservoirs, sand dams, and dig diversion ditches

Therefore, the answer is: (1) collapse; Reinforcement works such as blocking, net wrapping, excavation and anchoring; (2) landslides; excavation of drainage ditches or interception ditches to reduce the water content of landslides; (3) debris flows; Afforestation, construction of reservoirs, sand dams, excavation of diversion ditches and other projects

Forest fire Zaoxiao is a kind of natural disaster that is sudden, destructive, and difficult to dispose of stuffy rock silver.

a.That's right. b.Mistake.
