The aerial images of Wenchuan are heart-wrenching, and it is difficult to leave home and life is hard. How to arrange these villagers?

For Wenchuan, the hardest hit area, even post-disaster reconstruction is not a long-term solution. Villagers in Wenchuan should emigrate as soon as possible and stay away from this disaster-prone place. "Experts say that Wenchuan is already a dead city," said Liao Min, the county magistrate of Wenchuan County. Aba Prefecture has also sent an urgent report to the Sichuan Provincial Party Committee and the provincial government, applying for a site to build a new Wenchuan. ?

If you really don't want to leave Wenchuan, then you must plan ahead and be familiar with the flood risk map. The flood risk map is organized and drawn by government functional departments, which is convenient for people to know the scope of a certain magnitude of flood in the future in advance. Transfer the direction of retreat and safely transfer the destination. Using flood risk map can guide residents to evaluate correctly when choosing their residence, so as to avoid suffering from floods. Commonly used are flood risk map of river basin, flood regulation risk map, flood storage and detention area risk map and reservoir flood risk map.

General flood risk can be divided into four areas: (1) danger area, which refers to the area that reaches first when flood occurs. Flood with high head, high velocity and strong destructive power is the key prevention area. (2) the hardest hit areas, areas where floods may cause relative economic losses, and areas where floods last for a long time, which may cause serious house collapse and agricultural production reduction. (3) In the light disaster area, the flooding time is short and the flooding depth is small. Some countries and regions take whether the riverbed is flooded as the boundary, and those that are flooded but not flooded are light disaster areas. (4) The safety zone is not after the flood, but the area on the water is called the safety zone. It is a base for supporting disaster areas and resettling victims.

Wenchuan is located in the earthquake zone, so villagers should have enough safety awareness or move to other areas. I hope this disaster will not cause too much psychological pressure to the villagers in Wenchuan.
