Abstract:
The ancient Loulan, situated on the west bank of Lake Lop Nur, Xinjiang, Northwest China, was an important town on the Silk Road connecting China to Europe. However, this once-prosperous kingdom has been a depopulated zone filled with wind-eroded mounds since approximately AD 500–600. A comprehensive understanding of the environmental setting of the flourishing Loulan civilization is a prerequisite for assessing environment–human interaction there. Here, we present our survey, chronology, and archaeobotany (the identification of plant remains) of vegetation use for architecture from eight ancient ruins of the Loulan kingdom to clarify the ecological landscape on the west bank of Lake Lop Nur and to assess paleoenvironmental conditions when the Loulan kingdom flourished. Our results suggest that Populus euphratica, tamarisk ( Tamarix Linn), and reed ( Phragmites Trin.) were most widely used as building materials in this period. Wood utilization for buildings depended entirely on indigenous vegetation rather than that of the mountains in the Loulan kingdom, even though the Loulan was a predominant transportation hub on the prosperous Silk Road. Our reconstruction indicates that the west bank of Lake Lop Nur was sufficiently wetter than present conditions to support riparian forest growth composed mainly of P. euphratica, tamarisk shrubs, and reed meadows, until approximately AD 500. These wetter conditions and flourishing civilization accompanied an increase in precipitation in arid central Asia. Conversely, combined evidence of both archeological and paleoclimatic records from the water sources of Lake Lop Nur and ancient oases suggest that abrupt decreased mountain precipitation could be considered a significant environmental factor in the decline of Loulan kingdom.
