issueNational natural disaster risk situation in September

Recently, the Office of the National Disaster Reduction Committee and the Emergency Management Department, together with the Ministry of Natural Resources, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, the Meteorological Bureau, the Forestry and Grass Bureau and other departments and units, held a meeting.In September, the national natural disaster risk situation was discussed and judged.

According to comprehensive analysis,In September, the heavy precipitation weather in China is still frequent, and the autumn rain in West China has entered a concentrated period, and the risk of flood disasters in parts of southwest, northwest and northeast China is high; 2-3 typhoons landed or significantly affected China; There are periodic drought risks in some areas such as North China, Inner Mongolia and the eastern part of Northwest China. Sichuan, Yunnan and other local geological disasters have high risks; The forest fire risk rating in some areas such as North China, South China and Northwest China is relatively high. The details are as follows:

The first is the risk of flood disaster.estimateIn September, precipitation in most parts of Heilongjiang, western Sichuan, western Yunnan, southern Qinghai, Xinjiang, eastern Xizang and other places was higher than normal, with 20-50% more in eastern Heilongjiang and northern Xinjiang. Heavy precipitation and strong convective weather in these areas caused high risk of flash floods, wind hail and urban waterlogging. Rainstorms and floods may occur in Jinsha River and its tributaries Yalong River, Minjiang River and Tuojiang River in the upper reaches of the Yangtze River, Dongjiang River and Hanjiang River in the Pearl River Basin, river network areas around Taihu Lake and Zhejiang and Fujian areas, Songhua River in Songliao River Basin, and some rivers may have super-alarm floods.

The second is the risk of typhoon disaster.There may be 4-5 typhoons in the northwest Pacific and South China Sea in September, which is close to the same period of the year (4.9) to less; Among them, 2-3 typhoons landed or significantly affected China’s coastal areas, more than the same period of the year (1.6). There may be 1-2 disastrous typhoon storm surge processes in China’s coastal areas, 1 disastrous temperate storm surge process, and 3-4 disastrous wave processes in offshore waters.

The third is the risk of geological disasters.The risk of geological disasters in Zhejiang, Anhui, Hubei, Hunan, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Xizang, Shaanxi, Gansu and Qinghai is high. Among them, the risk of geological disasters in southern Sichuan, northwestern Yunnan and other local areas is high.

The fourth is the risk of high temperature and drought.At present, the soil in some areas such as the northeast of southwest China, the east of northwest China and the west of north China is moderately deficient. estimateIn September, the temperature in North China, western Inner Mongolia, northern and southern East China, northern Central China, eastern Northwest China and other places was 1-2℃ higher and the precipitation was 20-50% less. There was a staged drought risk in some of these areas.

The fifth is the risk of forest fire.Affected by factors such as high temperature, little rain and artificial use of fire,In September, there may be higher fire risk grades in northern Beijing, northern Hebei, central and eastern Inner Mongolia, northwestern Heilongjiang, central and southern Zhejiang, central and southern Fujian, southwestern Jiangxi, most of Guangdong, eastern Guangxi, western Hubei, western Hunan, northwestern Shaanxi, central and western Gansu and western Ningxia.
