Relevant units have arrived at the site for disposal. The ground precipitation in Fangshan Hebei town is nearly half a meter.

Fangshan is the hardest hit area of the "July 21"catastrophic natural disaster. According to the statistical data of meteorological observatory, as of 3: 00 on July 22nd, the place with the largest rainfall in the city is Fangshan Hebei Town. Its average precipitation is as high as 460 mm, reaching the level of rainstorm. Yesterday, when meteorologists interpreted the precipitation, they said that it was equivalent to an average of half a meter of water on the ground.

Sun, chief forecaster of the Municipal Meteorological Observatory, said that intuitively, 460 mm of precipitation means that there is 460 mm of water on the flat land, which is close to half a meter. In mountainous areas, the surface is uneven, and the water flowing down to low-lying areas or river valleys will cause local water accumulation of more than 460 mm, even ten times as much as it. Most of the ground in mountainous areas is not solidified, and high water flows downwards, which is easy to form flash floods. The impact of water flow will also wrap the soil and stones along the way, causing mudslides. Many mountain torrents are concentrated in Fangshan, causing serious floods. Suppose 460 mm of rain falls into the urban area, and the consequences are more serious. Because the soil in mountainous areas can still absorb water, the infiltration of urban hardened ground is limited, and the water accumulation will be more serious.

Besides precipitation, floods in mountainous areas and urban areas are also directly related to rainfall intensity. For example, Zhang Mingying, a senior engineer of the Municipal Meteorological Observatory, said that the effect of 20 mm rain in 10 minutes is not the same as that of a few hours of rain. The greater the rainfall intensity, the easier it is for the surface to form runoff, and it is difficult to infiltrate.

Fangshan: The direct economic loss of rainstorm exceeds 5 billion.

What is the rescue and relief situation in Fangshan District, which became the hardest hit area in the "July 21"catastrophic natural disaster? Yesterday afternoon, Fangshan District Government released the progress of this rainstorm rescue and disaster relief for the first time after the disaster.

According to preliminary statistics, 25 towns (streets) in the whole region were affected to varying degrees, and the affected areas basically covered the whole region.

"In the next step, Fangshan District will appease the families of the casualties and the affected people, continue to do disaster statistics and disaster relief work, and let the affected people resume normal production and life as soon as possible." Qi Hong added, "I believe that the expert group will work out a solution that will satisfy the masses as soon as possible." Two hours watching the road turn into a river.

In just over two hours, Mr. Pei watched the road in front of him turn into a river.

At 6: 00 p.m. on July 2 1, Mr. Pei and his family drove to a restaurant in Beizhuang Road, Yanshan District for dinner. "It's raining all the way, but it's not too heavy. Turn the wiper to second gear and I can see the road clearly. " Mr. Pei said.

"When we get to the private room on the third floor of the hotel and look out, the rain is getting bigger and bigger." Mr. Pei recalled that around 7 pm, the water in Beizhuang Road in front of the hotel had reached the knee position, and the water flow speed began to accelerate.

While Mr. Pei's family was eating, the pouring rain continued to push up the water level on the road surface of Beizhuang Road. The consequences of short-term water accumulation made the situation worse.

"Wait until around 8 o'clock in the evening, I looked at it on the road again, and I felt that the situation was wrong. This is not just as simple as a rainstorm, but has become a disaster. " Mr. Pei recalled the thrilling scene at that time and still had a lingering fear. "At that time, the water level almost flooded the hood of the car. I saw a car stall in the water. As soon as the owner got off the bus, the car was washed out of the water for more than 20 meters. Another van was washed away by the water, and a turn knocked down a street sign. "

The heavy rain continued, and by about 9 pm, the water had washed away the kerb and rolled up a white edge. The continuous high water level also makes roads dangerous.

"At that time, there was no road in front of the hotel. It was definitely a river. What impressed me most was that a person was washed by the current, struggling in the water, and a car was pushed towards him by the current. Although he hid quickly and escaped, he was washed away by the water. " Mr. Pei said that because the current was too fast, people were washed away almost in a short moment, and many people in the hotel failed to rescue them. "I hope this person is safe."

Until around midnight on the 22nd, as the rain became smaller, the water level in the hotel dropped to about knees, and Mr. Pei and his family hurried back to the car. "Fortunately, I parked my car in a high place, so I didn't get flooded. We deliberately found a way up the mountain to go home. "

"The speed of the disaster is so fast that there is almost no time to react." A few days later, recalling this experience, Mr. Pei still felt deeply. The rainstorm on July 2 1 in Beijing caused great losses to the landscaping achievements in Beijing.

The landscaping department made preliminary statistics on the disaster situation: the waterlogging area of fruit trees in the city154,000 mu was washed away by 65,800 mu, of which Fangshan District was the most serious, and * * * washed away 57,000 mu of fruit trees; The affected area of flowers is more than 2,300 mu, including 2,000 mu in Fangshan District, and 80 greenhouses were washed down, resulting in a loss of 1 10,000.
