Research On The Lower Yellow River System In Ming And Qing Dynasties From The Perspective Of Remote Sensing

Through the re-study of the passing locations of the Yellow River Jialu Paleochannel,the accurate positions of 17 reference points such as Baimaoji,Liuzhuang and Liangjingkou were determined.Using The ALOS digital elevation conducted model histogram equalization to identify the Baimaoji-Huanggu,Panjiakou-Shaogang,Sijiadaokou-Shijun Temple three river relics,at the same time the Yellow River breach was restored from Zhizheng four years of Yuan Dynasty(1344),Wanli three years and twenty five year of Ming Dynasty(1575);through the case study of the Yellow River Panlongji breach in the Xianfeng first year of Qing Dynasty(1851),it is determined that the flood caused by this breach flows southward through the canal channel The south and north sides of the Four Lakes spread.This year,the mainstream of the Yellow River has seen continuous flood peaks.The floods originate from three main areas in the Qin River Basin of Shanxi,the Wei River and Ming River Basins in Shaanxi,and the eastern Henan.The meridional movement of the subtropical high pressure caused by abnormal atmospheric circulation is closely related to the Zhejiang tropical cyclone landfall event;according to the basic principle of soil physical and chemical properties changes caused by the flooding of the Yellow River,the Landsat7 ETM SLC-on satellite digital product is used,and the tasseled cap is transformed.determining the specific distribution range of the flooded sediments from the Yellow River in Feng、Pei two counties;Discussing the problem of Mengzhu Pool and believing that the "Nine Rivers in Mingdu" in "Rongcheng’s" should have a corresponding relationship with the excavation of the Hong ditch,and the "Zhouhui" recorded by the ancients It should be referred to as the perimeter of the object,and the point of view recorded by Meng Zhu Pool in the "Shui Jing Zhu" in "Yugong Cone Finger" needs to be further discussed.Using the distribution of counties and towns in the Spring and Autumn Period and pre-Qin ruins,the approximate distribution of Mengzhu Pool in the pre-Qin period should be determined,which should not be within the area enclosed by Shangqiu,Yucheng,Shan and Cao County.
