摘要:
台风“摩羯”(国际编号2411)生成于2024年9月1日,8日停止编号,6日达到极端强度并于当日22:20左右登陆广东省徐闻附近区域,环流庞大、台风持续、暴雨增水对各类生产生活造成重大威胁,给应急遥感监测提出新的挑战。通过应急调度拍摄台风侵袭区域高分辨率合成孔径雷达影像,分析台风中心附近核心区短临增水显著、强风影响作用损失。基于高精细数字高程模型划定斜坡单元,并构建以斜坡单元为基础的地质灾害防御评价指标方法,快速评价台风环流影响强降雨区不同防御等级。试验表明:台风作用下核心区耕地种植情况总体影响较轻,主要增水区分布沿岸附近尚未造成农作物大面积淹没;海堤西北至中段防护效果明显,尚未出现大面积越浪淹没现象,在东段海堤防护范围内出现较大范围陆域淹没;筏式养殖区总体损失较轻,少量养殖设施出现侵没。台风作用下环流强降雨区地质灾害防御评价结果总体与在库隐患点在空间上表现一致性,各级防御区呈统计正态分布。说明国产商业高分辨率合成孔径雷达能够满足台风作用下耕地种植作物淹没、海堤风暴越浪以及海上养殖设施安全防灾减灾要求,地质灾害防御区快速评价指标在应急遥感监测中具有可行性。
Abstract:
Typhoon Yagi (International No. 2411) formed on September 1, 2024, and was decommissioned on Sep?tember 8. It peaked in intensity on September 6, and made landfall near Xuwen, Guangdong Province at around 22:20 on the same day. The huge circulation, continuous typhoon and rainstorm increase water pose a major threat to all kinds of production and life, posing new challenges to emergency remote sensing monitoring. The study acquired emergency dispatch to capture high-resolution synthetic aperture radar images of typhoon affected areas via emer?gency imaging scheduling, and analyzes the significant short-term water surge and wind-induced losses in the core area near the typhoon center. And based on high-precision digital elevation models, slope units are delineated, and a geological hazard defense evaluation index method based on slope units is constructed to quickly evaluate the im?pact of typhoon circulation on different defense levels of rainstorm-hit zones affected by typhoon circulation. The ex?periment shows that: The overall impact of the typhoon on the cultivation of arable land in the core area is relatively light, and the main water increasing areas are distributed near the coast, which has not yet caused large-scale flood?ing of crops; the protective effect of the northwest to middle section of the seawall is obvious, and there has not been a large-scale wave inundation phenomenon. Within the protection range of the eastern section of the seawall, there has been a large-scale land inundation; the overall loss of raft aquaculture areas is relatively light, with a small num?ber of aquaculture facilities being encroached upon. The evaluation results of geological disaster prevention in areas with heavy rainfall caused by typhoons are generally consistent with the spatial performance of hidden danger points in reservoirs, and the defense zones at all levels show a statistically normal distribution. The domestically produced commercial high-resolution synthetic aperture radar can meet the requirements of crop submergence in farmland un?der typhoon action, storm surges on seawalls, and safety disaster prevention and mitigation of offshore aquaculture facilities. The rapid evaluation index of geological disaster defense zones is feasible in emergency remote sensing monitoring.
