Some time ago, Beijing, Wuhan, Hangzhou and other cities serious waterlogging, a huge loss. Since the flood season this year, the province weather complex, frequent extreme weather disasters. Reporters from across the province held yesterday, the main flood season flood television and telephone conference was informed that as of June 23, the province due to floods caused a direct economic loss of 1.33 billion yuan, 2.14 times the average for many years, is 3.67 times the same period last year. . Among them, Liangshan, Pakistan, the Nanchong three flood season of disaster losses, the province accounted for 71% of the total losses. July 1, the main flood season approaching, the province's flood prevention and emergency unit will enter alert status, a new generation of weather radar meteorological departments will be 24 hours, close monitoring of weather trends, so that the process left off every time the weather; water sector will also be continue to adhere to the nearly 2000 dangerous reservoirs to conduct an intensive investigation.
Analysis: the province's flood situation grim
Department of Water Resources Director the main flood season in the province just cold flood of television and telephone conference , said some time ago from the province of rainfall characteristics, which can be summarized as "two fast two-dilemma." "Two fast" convergence is fast, disaster soon. In just several minutes or several hours, up to hundreds of millimeters of rainfall, flow up to once in several decades, down steep rise in steep, ferocious, instant disaster. "Two strong" is the local strong, destructive strength. Several towns, several villages and even in the smaller range, the local emergence of "small-scale, high-intensity" of the heavy rainfall on rural housing, roads, cities and towns with devastating damage. "Dilemma" is hard to predict, difficult to rescue. Extreme weather events frequent, heavy rains no rules to follow, often unpredictable; in the storm surge down, stormy weather conditions, emergency rescue team is difficult. In particular, some mountain streams streams, small villages, scattered farmers as information, transportation and other reasons, appear to be normal, seemingly not affected where, once the disaster, there is no time and opportunity to rescue.
Just cold analysis, the current flood prevention work in the province, "a freshman high school more" situation. "Big" is the flash flood risk, defense situation is not optimistic. By the early impact of heavy rainfall, soil moisture is already saturated, increasing the localized torrential rain, landslides, mudslides and other geological disasters risks. "A high" high water level of rivers, lakes and reservoirs, flood control pressure. Since the early rainfall, and regional focus, some rivers, lakes, the water level already high, coupled with heavy rainfall on the part of the reservoir, causing varying degrees of damage to the embankment, leading to the flood control capacity has declined. "One More" is the earthquake hazards and more, can not guard against the slightest slack. Earthquake mountain broken loose surface soil moisture saturation, "top-heavy", large-scale geological disasters, the possibility of flash floods is still there.
Meanwhile, the reconstruction project has not been fully tested by flood, earthquake flood situation is very grim. According to the characteristics of the main flood season this year and the situation, the provincial Water Resources Department at all levels to do flood control agencies and water departments reservoirs, dikes, flood safety in construction work, work to improve urban flood control, prevention of flood disasters, earthquakes, flood disaster, to implement security measures.
Prediction: the province will appear the phenomenon of drought and staggered
At yesterday's provincial flood control and flood fighting work the main television and telephone conference , the provincial Meteorological Bureau Peng wide analysis, the main flood season is summer in our province in July and August, the province will appear the phenomenon of drought and staggered, some local emphasis is likely to flood. He disclosed that during the main flood season, meteorological departments at all levels in our province will strictly enforce the flood leadership 24 hours with a class system, strengthen the monitoring, forecasting business duty class system; adhere to a new generation of weather radar 24 hours a day, close monitoring of weather trends, so that Every time the weather process left off. Meanwhile, the province will improve the whole network of early warning signals SMS publishing process and the green channel, and news media outlets to establish rapid linkage mechanism, full use of modern media means, quickly through radio, television, SMS, Internet, information telephone, electronic display screen, big speakers and other platforms and channels, providing the public a convenient weather services.
According to the provincial meteorological bureau analysis, this flood season, relatively stable weather and climate in our province. Occurred in early May 2 local strong convective weather, June 16, 21 have appeared in two sub-regional heavy rainfall, localized flash floods and geological disasters. May to June, the province's weather and climate occur four characteristics: high temperatures, the magnitude of changes significantly; Rainfall in North-South uneven distribution; lighter summer drought, the main drought-stricken areas in southern Sichuan; rain coming early, widely distributed , local rainfall intensity.
June 16 to 17 of the heavy rainfall during this year's first regional storm, after the first year Ruxun regional market one month ahead of heavy rain, heavy rain caused 23 counties, three counties heavy rain, Liangshan Seoul sleep state Yuexi total rainfall of 145.4 mm Township; June 21 to 22 heavy rainfall caused by heavy rain 24 counties, 6 counties heavy rain, some parts of Pakistan and the cumulative rainfall 400 mm, rare historical period.
Provincial Meteorological Bureau, Pang-kwong, said, according to the latest data analysis, the province from July to August, summer droughts staggered, some places emphasis on the possibility of large floods. Normal summer temperatures in most areas of the province slightly higher. Mid-July, the eastern parts of the basin in late summer there is a general occurrence.
July to August, most of western Sichuan Plateau, northeast and south of the basin a bit more normal rainfall, rainfall in the rest of the province. Among them, most of western Sichuan Plateau in July, Rainfall in the northeast basin, the rest of the province slightly below normal to normal rainfall; August, most of western Sichuan Plateau, Basin Rainfall in the northeast and south, a bit more normal rainfall the rest of the province less.
Expected in late June to late August, the Yangtze River uneven spatial and temporal distribution of precipitation, compared with year-round, the upper reaches of the Jinsha River, Min, Tuo ones 1-2 into the Jialing River in Chongqing and Yibin to slightly below normal in most areas.
According to the provincial meteorological bureau forecast, summer period, the Sichuan Basin has a general flood occurred. Total precipitation, western Sichuan Plateau central, northern region of 300-400 mm, west of the basin, the central region of 450-500 mm in the western Sichuan plateau south, southwest and northeast of the basin area is 500-650 mm, northeast of the basin and Deyang , Mianyang, Dujiangyan , earthquake and other flood Yingxiu emphasis.
Investigation: the province's nearly 2000 dangerous reservoirs do not stay dead
Reporters learned from the meeting, the province's nearly 2000 dangerous reservoirs ongoing intensive investigation, the rectification campaign-style, hidden danger dangerous reservoirs will not stay dead, do not stay hidden, and a responsible person to do a reservoir, a a reservoir flood plan. In addition, the province has built 5000 kilometers dike revetment. Other projects under construction in the dike must be the premise of ensuring quality, speed up the progress of the project, to ensure the construction section to flood height; addition, the province will clear the flood barrier according to the law to crack down on illegal occupation of the river, sand and other illegal acts, to ensure embankment stability and flood safety.
According to the reporter, the province is also investigating the city flood control and drainage system, pay close attention to the existence of hidden, underground facilities, each review of an important flood control capacity, pay close attention to the urban drainage network to conduct an intensive investigation, take timely risk-elimination for the problems and remedial measures.
