In the past century, it has long been debated in the archeological, historical, geographical, and many other related communities where the capital of the Luolan and Shanshan states was in the Lop Nor region. This paper presents three AMS radiocarbon ages from a newly-discovered ancient city at about 6.3 km to the northwest of the xiaohe Graveyard, and fifteen new radiocarbon ages from the Loulan (LA), LE, Qieerqiduke, Milan, and Tuyin sites in Lop Nor. The new investigation shows that the age of newly-discovered ancient city is at ca. 440–500 AD, belonging to the Northern Wei Dynasty (386–534 AD). This is about 100–300 years younger than Loulan (ca. 100–230 AD), LE (ca. 230–300 AD), Qieerqiduke (ca. 200 AD), and Tuyin (ca. 100 AD). A wooden beam from Milan fortress is dated to ca. 370 AD, while the age on north wall at west gate of the fortress is younger, around 770 AD, suggesting that its construction time might be at the Tang Dynasty. According to 14C ages, cultural relic style, and the geographical location, the newly-discovered ancient city is probably attributed to "Zhubin City", as documented in the historical literature. Temporally, we name the city "ancient Zhubin River City". However, the characteristics and functions of this ancient city are largely unknown and need more detailed archaeological excavation and investigation in the future. Given its location near the ancient postal relay of Alagan on the crossroad, there is no doubt that the newly-discovered city was at an important geographical position on the Silk Road, no matter whether it was called "Zhubin City", or "Lielo City", or the capital of Loulan state–"Yuni City". Our findings provide new evidence for the temporal and spatial distribution of ancient relic sites and the development of civilization in western China, thus contributing to our understanding of the relationship between human activities and environmental change in the Lop Nor region.

作者： xia xuncheng and Yang Gensheng(Institute of Desert Research, the CAS, Lanzhou)

This paper describes an exceptionally severe sand-dust storm that occurred in Northwest China in 1993, and outlines the damage, characteristics and formative factors of the sand-dust storm and the demarcation of its prone zones, laying emphasis on the countermeasures to prevent and reduce such disasters. Finally the authors suggest setting up protective systems for oases and taking action to rehabilitate the blown sand-land on the northern side of the Great Wall on the Loess Plateau.

Research of desert science in China began in the 1930s, when Chen Zongqi et al. first made apreliminary investigation in several deserts. Shortly after the founding of the People’s Republic ofChina a few studies were carried out to meet the demand for the establishment of windbreak andsandbreak forests, for example, the studies of moving sand dunes in Yulin. Jingbian and Dingbianregions of Shaanxi Province. However, the comprehensive study of desert science in China

塔克拉玛干沙漠南缘安迪尔故城红柳沙包剖面孢粉分析结果表明：1792年以来,安迪尔故城地区孢粉组成以草本植物花粉为主,灌木植物花粉次之,乔木植物花粉较少,蕨类孢子和水生植物含量较低,植被演化经历了荒漠灌丛-荒漠草原-荒漠灌丛的演替过程。利用转换函数法进行的古气候定量重建结果显示,相对于研究时段的平均值,研究区气候变化经历了3个阶段：1792-1905年为暖干期,气温逐渐上升,年平均气温为10.6-12.6℃,降水量变化在33.4-70.4mm之间,期间出现若干个小的冷暖交替期;1905-1950年气候冷湿,气温下降明显,年平均气温为9.5-11.7℃,降水明显增多,降水量变化在52.9-95.1mm之间;1950年后为暖湿期,气温逐步回升,平均气温为10.2-12.2℃,降水变化在47.3-81.6mm,仍相对湿润。
