It was identified that rice have been cultivated there since about 6000 years ago by detecting a great number of plant opals in soil samples and earthenware fragments from this site. Further, analysis of morphological characteristics of the plant opals of rice showed that the vertical, horizontal and lateral lengths had rise and the b/a had fell with changes of historic times, but there were some times such as the early period of the Hemudu culture dating from 5000 B.C. to 3900 B.C. and the Maqiao-Shangzhou period dating from 1700B.C. to 770B.C. when the changes were the opposite to those. Changes of discrimination scores appeared to be same as those of vertical, horizontal and lateral lengths, but those of the periods of the Hemudu culture were numerically smaller than 0.5, appeared neuter. From those result, it was proposed that the rice was varied in the periods of the Hemudu culture and would change to a great deal cultivated japonica rice from then on, but there was possibility of developing of indica rice, during those times.展开更多

Among them are Profs. Tong Zhuchen, Shi Xingbang, Li Xueqin, Mai Yinghao, Zhang Senshui, Hanwei and Liu Qingzhu from China, and Prof. Machida Akira from Nara National Cultural Properties Research Institute of Japan. Based on their personal experience, they look back on the course of the Institute as the center of Chinese archaeology in the past 50 years and place great hopes on its future.展开更多

The remains revealed include the platform-foundation of the pavilion with the traces of mural columns, as well as passages, aprons, steps to the pavilion, patios, countyards, and the vestiges of auxiliary buildings. Among the unearthed terra-cotta objects are bricks, tiles, tile-ends, lamps, and spindle whorls, many bricks and tile-ends bearing designs and inscriptions respectively. Besides, there are iron articles and copper coins. The buildings in Area B and the high earth-rammed terrace to the north formed a complete palace complex together with the previously-excavated buildings in Area A, and constituted an important part of the Western Han imperial palace.展开更多
