据水利部介绍，6月以来，我国南方地区暴雨洪水频繁发生，部分地区洪涝灾害严重。全国共有433条河流发生超警以上洪水，其中109条河流发生超保洪水，33条河流发生超历史洪水。
当前，我国南北方全面进入主汛期，强降雨天气频发，防汛抗洪已到关键阶段。在今年的防汛抗洪中，从监测预警到防御救灾，各种科技设备和前沿技术成为“利器”，有效保障了人民群众的生命财产安全。 China is entering a critical period of flood prevention.Affected by the recent heavy rainfall across the country, the water levels of 433 rivers in China have surpassed danger level since early June, 33 of which hit historical highs, said the Ministry of Water Resources on Monday.From early warning systems to rescue missions, various forms of sophisticated technology have been used to save lives and property in the fight against floods.China's BDS warns of geological disasters刚完成全球组网的北斗卫星导航定位系统在防汛救灾中发挥了重要的作用。进入汛期以来，暴雨洪水不仅带来了洪涝灾害，也导致一些地区发生山体滑坡等地质灾害。而北斗卫星导航定位系统可以对山体进行实时变形监测，智能评估其安全状况，并对可能的滑坡险情进行提前预警，从而避免人员伤亡的发生。The recently completed BeiDou Navigation Satellite System (BDS) has played an integral role as an early warning system for geological disasters caused by floods.Several rounds of heavy rainfall have hit Shimen County in south China's Hunan Province since the start of this year's flood season.A massive landslide occurred there on July 6, after heavy rains caused 3 million cubic meters of a mountainside to collapse. The area was evacuated before the incident occurred, and no one was injured.On June 24, Shimen County officials were notified of a potential geological disaster based on BDS' findings. The satellite detected anomalies in the monitoring data of hidden geological hazard points, CCTV reported.The local authorities immediately relocated residents in nearby villages. Right before the landslide on July 6, another batch of villagers near suspected danger zones was evacuated.Wang Dunlei, who is in charge of flood and drought prevention in Changde City, told CCTV that with high-tech means like BDS, the city can identify danger zones in advance and avoid casualty.5G、虚拟现实（VR）、无人机、水下探视仪……在今年的防汛抗洪中，一系列高科技设备大显身手，助力防汛抗洪。比如低延时的5G信号可以将360°全景摄像头拍摄的内容及时、高清地传递给监测人员，方便他们实时掌握水位情况，提高汛期巡查工作效率；高精度的传感器可以在汛期时将一些地区的易积水区域标注在可视化地图上，让工作人员通过系统平台进行远程控制和隐患排查；无人机、机器人等设备不仅能勘探灾害现场、及时回传信息，还可以营救被困人员或是投送救援物资。In Anqing City in east China's Anhui Province, a local telecom operator uses 5G technology and virtual reality (VR) to observe water levels in real-time.With the low-latency 5G signal, monitoring personnel can quickly receive footage shot by 360-degree cameras and observe even subtle changes in water levels through VR goggles, thus increasing the efficiency of inspection during the flood season.The intense rainfall has caused severe flooding and waterlogged the soil in many cities in the country.In cities such as Fuzhou in southwest China's Fujian Province and Guiyang in southwest China's Guizhou Province, areas that easily accumulate water are marked on a map so that when it rains heavily, monitoring personnel can check the real-time status of each catchment area without the need to go out into the field.High-tech hardware like drones and rescue robots have also made significant contributions to saving lives during the flood season.
