What are the explanations of terms in Chinese history and geography?

The historical aspects include: the four major academies, the eight major ancient capitals, the four famous buildings, the Battle of Feishui, the Battle of Chibi, the Public Security Rebellion of Zhenguan, the Rebellion in History, Wang Anshi’s Reform, Wang Shuwen’s Reform, and the disastrous defeat of the Eight Sima Tumu Fortress, etc.

Geographical aspects include: 1. Meiyu? A large-scale precipitation climate characteristic that often occurs in the Jianghuai region in early summer. Abundant precipitation? High relative humidity, lots of clouds, wind, and sultry atmosphere.

2 . Cold wave? An atmospheric phenomenon with a large cooling rate in the winter half. The standard daily temperature drop is higher than 10 degrees? The daily temperature anomaly is higher than 10 degrees? The daily temperature anomaly is 5 degrees higher.

3. The occurrence of drought? In late July or early August, that is, after the Meiyu, a dry weather phenomenon is formed under the control of subtropical high pressure. 4. Dry and humidity zonal distribution and contrast between land and sea form the difference between continental climate and oceanic climate. Continent What are the differences in vegetation types within the interior and on the east and west sides, as well as the difference in dryness and humidity of the landscape? This difference often changes in the direction of longitude differentiation, so it is often called longitude zonality, or dry-humidity zonality.

< p> 5. Tidal flat? The transition zone between sea and land? Its landforms, sediments and soil are closely related to tides, waves and sediment sources.

6. Kuroshio? Warm current? North Pacific subtropical general circulation system The western boundary current in the center is characterized by strong flow speed, large flow, narrow flow width, extended tunnels, high temperature and high salt content. Its current is called the Kuroshio because of its dark blue water color, which looks black from a distance.

< p> 7. Cold island effect? ??The protective forest and crops inside the oasis slow down the wind speed? Evaporation is strong? The relative humidity increases? The change of the underlying surface reduces the temperature variation and the average value is lower than the surrounding desert. These characteristics are not only beneficial to the oasis The process of naturalization continues, and it also plays a certain inhibitory role in the invasion of deserts near the oasis.

8. From the perspective of natural attributes, land resources refer to geology, topography, climate, hydrology, vegetation and soil. A natural complex composed of other elements, its nature depends on the combination relationship and comprehensive characteristics of land elements. From the perspective of social attributes, it is social wealth with economic characteristics that can promote the development of agricultural production.

9. The law of regional differentiation refers to the regular spatial differentiation phenomenon that occurs in the entire landscape or the various components of the geographical environment according to a certain direction. 10. Regional culture is formed within the geographical unit of a certain area and is based on a certain regional concept. A systematic culture formed within a clear geographical scope.

11. Traditional culture refers to the material culture, institutional culture and spiritual culture with certain characteristics that were formed and passed down during the historical development of China. The sum of.
