According to "Earth Sky" magazine January 16, Northwest China is one of the driest areas in the world. Scientists use UAV to discover that as early as 1600 years ago, irrigation systems emerged in the area, which provided favorable conditions for agricultural industry.
Archeologists use UAV and satellite imagery to find that irrigation systems have emerged in arid areas along the Silk Road. Experts say irrigation systems provided favorable conditions for local farmers to develop livestock husbandry and farming.
The Silk Road is a trade route between ancient China and the West for trade and commerce. It is a link between the two ancient civilizations, Rome and China, for trade exchanges and for ideological and cultural exchanges. After studying the discovery, Li Yuqi, a doctoral student at the University of Washington, began his research on the Silk Road.
"This ancient agricultural land of civilization has been asleep for years at the foot of the barren hills of Tianshan. Its remains are hidden in the endless desert plains and If you stand here They look like scattered pebbles and criss-crossed sand But if you look at it over 30 meters using drone and professional image analysis software, you will find traces of past dams, canals and small farm tanks, "said Li Yuqi. The preliminary test excavation also confirmed the existence of farmhouses and graveyards.
A preliminary analysis was released in Asia in December 2017 by the Journal of Archeology and Technology Studies showing that the Silk Road irrigation system was built by local herdsmen in the third or fourth century AD for increasing grain production and livestock husbandry.
