Fortune teller says Henan flood _ What does fortune teller mean by Henan flood?

Why is Henan the hardest hit area of all kinds of disasters in past dynasties?

Since ancient times, floods have occurred frequently in Henan, and the reasons for being deeply troubled by floods are as follows:

1, the climate zone is complex.

The distribution of climatic zones in Henan Province is complex. The area of Henan province spans the Qinling-Huaihe line, which is the geographical dividing line between the northern and southern parts of China. The south of this line belongs to subtropical zone and the north belongs to warm temperate zone.

Nanyang City, Xixia County, Xichuan County, neixiang county City, dengzhou city City, Xinye County, tanghe county City, Tongbai County, Biyang County, Queshan County, Xixian County, Zhumadian City, runan county City, Pingyu County and Xincai County are all located in this north-south dividing line. Therefore, most parts of Henan Province are in the warm temperate zone, and the south of Henan Province crosses the subtropical zone, which belongs to the continental monsoon climate of transition from warm temperate zone to subtropical zone.

At the same time, it also has the characteristics of transition from plain to hilly and mountainous climate from east to west. As a result, the climate in Henan Province is complex and changeable, and meteorological disasters occur frequently.

2. The geographical and hydrological environment is special.

The topography of Henan Province is mainly composed of plains, basins, mountains, hills and water surfaces. There are four major river basins in Henan Province, namely, the Yellow River, Huaihe River and Yangtze River. There are 560 rivers in the province, with a drainage area of 100 square kilometers. Due to the difference of topography, it is not easy to flood when the water potential is fierce in flood season, and it is easy to form mudslides, floods and other disasters.

Affected by many factors, the water level of the Yellow River has been changing all the time in history. In particular, the middle reaches of the Yellow River flow through the Loess Plateau, carrying a lot of sediment, so in the lower reaches, the riverbed is higher than that on both banks because of sediment deposition.

Influence of the Yellow River on Henan Province

As the mother river of the Chinese nation, the Yellow River not only nurtured the people on both sides of the strait, but also caused huge floods. China has attached great importance to the management of the Yellow River since ancient times, turning harm into benefit. "Governing the Yellow River" is an important policy that successive dynasties attached great importance to. 1In February 1946, the government of Shanxi-Hebei-Shandong-Henan Border Region established the Hebei-Shandong-Henan Yellow River Old Course Management Committee, and in June 1949, it was renamed the Yellow River Water Conservancy Committee.

After the founding of New China, the Yellow River Water Conservancy Commission was changed to a vice-ministerial organization directly under the Ministry of Water Resources, with subordinate institutions covering 9 provinces and regions in the Yellow River Basin and 40,000 employees. The surging Yellow River is a natural barrier, so it is often regarded as a natural military barrier.
