The main flood season precipitation is about 600 mm, compared with perennial slightly more　　

Recently, Ningbo, sky blue, and occasionally a little shower. About 18:20 yesterday, the reporter in a high-rise on Haishu see rare double rainbow in the sky.
Each year on July 15 Day to October 15, the city vulnerable to typhoon triggered flood Taiwan as the main flood of the main flood season. Reporter yesterday, the municipal government held a flood control and anti-working press conference was informed that the main flood season this year is expected to have 2-4 Typhoon affect the city, close to the average annual level of 3.1; precipitation of 600 mm, than the normal 543 mm slightly more.
　　Special geographical topography and meteorological conditions, the city is a typhoon, heavy rain, high tide, drought staggered, multi-disaster concurrent region. According to statistics, since the founding of a total of more than 160 wind affect the city, with an average of 2-3 per year, the cumulative result in economic losses of over 20 billion yuan, the death of more than 4,000 people.
　　Unlike previous years, the city this year, pre-flood is more serious. 1-6 months, the face of the city's average rainfall over last year the high side 60%, compared with normal years of 43%, close to the highest annual rainfall, the city has 68 villages and towns in six counties (cities) and districts affected to varying degrees, the direct economic losses .76 one hundred million yuan. In July, the day after the main flood season, Yin West region are rare heavy rainfall, the Dragon King River Basin, three hours rainfall of 195 mm, resulting in three villages and towns affected the Yin west region, the direct economic losses of 055 million million. Pre-flood and disaster caused by flood prevention work on the next phase of the pressure.
　　According to the department of meteorology, hydrology analysis and forecasting of tropical cyclone activity in August-September this year than normal active typhoon disasters heavier than last year. Currently, the city's reserves of 1.7 million (article) a variety of bags, assault boats, rubber boats, 140, and emergency power generation equipment, pumps, sand stone and rescue equipment and other flood control materials. The city's disaster relief team organized a professional training and drills; levels of flood control, hydrological institutions of Hydrology forecasting, monitoring of the engineering conditions, flood control and early warning, communications security facilities and equipment to conduct a comprehensive maintenance debugging, the current safety and normal operation.
　　In yesterday's press conference, the person in charge of the Municipal Water Conservancy Bureau also reminded, flash flood-prone area residents in the flood season often listen to and watch the disaster danger forecast meteorological information and the higher authorities released, pay close attention to and understanding of the location of the rainfall regime, hydrological changes, be aware of. Residents of the residence is a danger zone, must be seriously familiar with the residence in which the position and flash hazard situation, determine the routes and places of contingency measures and the safe transfer. Diligent the observed Fangqianwuhou mountain cracking, subsidence, tilt and displacement of local changes, whether well water turbidity, the ground suddenly to take the phenomenon of muddy water, flora and fauna abnormal response. Discover the obvious precursor, it should quickly and decisively to withdraw from the scene. Residents living in the warning area should also be ready to do the necessary preparations for disaster relief, security transfer, cash should be deposited in a bank, not hidden in the home.

　　This year the city's flood prevention work is still facing problems and difficulties
　　This year's flood control and anti-there are three adverse factors
　　According to to Yeli Guang, Vice Secretary of Ningbo Municipal Water Conservancy Bureau, the city's flood control and disaster ability has been greatly improved, but this year's flood prevention work is still facing many problems and difficulties.
　　First, flood control and the weak link is still outstanding. The city's rivers and flood control compliance rate is not high, such as water infrastructure, urban flood control closed area has not yet formed, lagging behind the construction of flood control projects, flood threat is serious; plain drainage system is not perfect, the construction of drainage projects mostly single project. drainage the overall effectiveness is difficult to play; small mountain basins, ponds and treatment rate is not high, the losses caused by flood disasters is still large.
　　Two non-engineering measures. At present, construction of flood control of the city in a flash flood prevention, urban waterlogging non-engineering measures is not yet complete, lack of the sudden floods monitor the early warning and response capacity is still quite prominent.
　　Defensive super typhoon flood and watershed exceed the standard foundation is weak, the relative lack of combat experience.
　　This year's flood control and anti-there are three adverse factors
　　First, the threat of extreme sudden climate. Frequent phenomenon of extreme climate world-wide in recent years, the city's sudden heavy rainfall, coupled with the city had not been encountered in recent years a large typhoon positive attacks, people are likely to produce paralysis of thought, flood control and reduce the anti-Taiwan vigilance, while many new facilities were not big typhoons, can easily become the hidden dangers of the flood control and anti-work, and pose new threats and challenges on the flood prevention work.
　　Radar observations of the high water level of reservoir river network. Current reservoir ponds and impoundment generally sufficient, the city's 30 large and medium-sized reservoir storage of 961 million cubic meters, accounting for 91.5% of the total controlled accumulator the Yin west region Zhougongzhai, Jiaokou two reservoirs and related The river water level is still excretion dropped. Radar observations of reservoir river network to the higher water level, more favorable to guarantee water supply security in the second half. But at the same time, coupled with the early rains led to soil saturation due to its regulation and storage capacity has been weakened after the radar observations in case of typhoon strength storms, relatively easy to cause floods.
　　In construction projects related to flood control and hidden dangers. More this year in the construction projects related to some linear engineering investigation and rectification of the pre-hidden has made great achievements, but there are still individual water blocking or poor drainage.
