Ningxia is located in northwest China, with an area of less than one-tenth of Qinghai.
In Ningxia Hui Autonomous Region, the number of ruins left by the ancients in the metal-free era ranks tenth in the country after Shaanxi, Shandong, Shanxi, Gansu, Henan, Inner Mongolia, Hubei, Hunan and Qinghai. The average density of the site ranks fifth in the country.
Why did the ancients choose to live in Ningxia five thousand years ago? Where do they live in Ningxia?
In the late Neolithic Age of the Metalless Age, most of the ancients in Ningxia chose to live in the southern part of Ningxia and live along the water source of Liupanshan .
Liupan Mountains are clustered with trees and rivers form a network, forming a "wet island" on Loess Plateau .
can be seen on the distribution map of the metal-free era sites. Baoji in Shaanxi, Qingyang in Gansu, Pingliang in Ningxia, and Guyuan in Ningxia, all are big reds with high residential density. It is nourished by the Liupan Mountains water system, and this big red area is a highly dense site. Five thousand years ago, there were more than three ancient settlements within a range of 100 square kilometers between hills, ridges and ravines.
5,000 years ago, along the lush Liupan Mountains, today, in Baoji, Shaanxi, Qianyang County, Qishan County, Fufeng County, , Fengxiang District, , Weibin District, , Jintai District, , Zhenyuan County, , , Kongtong District, , Zhuanglang County, today, in Baoji, Shaanxi, walking a range of ten kilometers, you can see more than 5 settlement points.
site density map is compiled based on tens of thousands of data from the residence of ancient people in the metal-free era in " Chinese Cultural Relics Map ".
The distribution map of metal-free era sites drawn according to the number of sites accurately reached by each district and county can show us the distribution of ancient people’s residences five thousand years ago.
Why do we need to know where the ancients lived five thousand years ago?
On the land where we rely on, the geographical environment is closely related to our lives.
If you want to obtain the laws of geographical environment changes, you need to observe the geographical and geomorphology of the same region over a longer period of time and record the observation results for comparison. The text appeared in the Bronze Age, and the geographical environment conditions in the Metal-free Age were not recorded in writing.
The ancients who lived in the metal-free era voted for the living environment with their feet. As an immovable cultural relic, the ruins leave us with the results of the ancients' vote on the living environment that year.
The livability of the geographical environment in the metal-free era is truly demonstrated through the density and number of sites on the site map. The ancients' residences on the
site distribution map, with intuitive density and accurate number of sites, give us a reliable basis for comparing the current and past geographical environments of the same area on the map. Let us see the differences in the past and present in geographical appearance.
The metal-free era and today, at both ends of the thousands of years, the population distribution situation in many places has changed significantly. Shaanxi, Gansu, Qinghai and other places, with abundant water sources and prosperous populations on hillsides five thousand years ago, high-density residences were now drought and barren, and the ground was desertified. Hubei, Henan, Shandong and other places, lakes, swamp wetlands that were uninhabited five thousand years ago are now densely populated fertile plains. The trend of environmental changes emerges immediately.
For five thousand years, the geographical environment has changed from wet to dry.
On the long roll of time when the geographical environment changes from wet to dryness, climate is a big move to describe the geographical appearance. After entering the metal age, the material of the tool was metalized, and humans held sharp tools and wiped out green in pieces on the long roll of time. From shaving half a green mountain in the tomb of the Han Dynasty to make yellow intestines to make , to cutting a bunch of logs in modern times to making steel by cutting out the soil. The excellence of metal weapons has brought about large-scale wars and has also driven away the large animals in the mountains.
The fracture of biological chain and the drying trend of the natural environment are mutually affecting each other. The area of lakes and wetlands has shrunk, forests have disappeared, groundwater levels have dropped, crop natural enemies have dropped sharply, and pesticide usage has increased dramatically. . . . . .
The unscrupulous hunting of humans has accelerated the process of environmental drying.
