基于Sentinel-1A的2016年长江中下游重灾区洪水遥感监测及灾情评估
Flood Remote Sensing Monitoring and Disaster Assessmenton in Heavy Disaster Area of the Middle and Lower Reaches of Yangtze River in 2016 Based on Sentinel-1A Imagery
摘要
Abstract
Based on the Sentinel-lA radar imaging system,the flood period in the hardest-hit region of the middle and lower reaches of Yangtze river(115°-117° E,28°-31° N) between the May 18 to August 10 of 2016 was divided into accumulating period,flooding and stabilizing period,the temporal dynamic monitoring was observed and the inundated areas of different phases was obtained quickly,which would help to understand the process of flooding condition comprehensively.The results indicated that,from May 18 to August 10,the sum of inundated areas in the study was 2 096.95 km2 and low-lying regions around the large lakes and rivers were submerged seriously.Among the country-level administrative units,the heaviest hit region was the southern area of Anhui Province and the serious country was Susong with the damage area of 290.09 km2.In terms of the cover types,the most serious types were cultivated lands and the inhabited area which accounted for 80.33％ of the whole inundated areas,the sum of the inundated cultivated lands and the inhabited area were respectively 947.45 km2 and 76.06 km2.The most serious hit region of dry lands was the country of Huaining in Anhui Province,its inundated areas was 150.95 km2 which accounted for 22.55％ of the whole inundated dry land;The most serious hit region of paddy field was the country of Susong in Anhui Province,its inundated areas was 90.58 km2.The inhabited area of Huaining in Anhui Province accounted for 16.89％ of the whole inundated paddy field.关键词
