The relative sea level changes are discussed according to the lab results. The record indicates that the region where the Tianluoshan site located has witnessed at least three times of relative sea level high-stand before, during and after the Hemudu period. Based on previous researches, this paper also focuses on discussing several environmental elements, the inter-relationships between environmental condition, human activities and development of the Hemudu culture comprehensively.展开更多

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

Noticeable achievements were obtained through excavation in 1996. The site contains deep deposits and rich remains, including tombs, ash-pits and wells. Beneath the eighth layer,remains of pile-dwellings have discovered in three units in an extensive area and can be reliably divided into two phases with respective technical features. Among the unearthed objects are many types of pottery articles, as well as a wide variety of wooden, bone and flint-chipped artifacts. The site corresponds to the Hemudu site in deposition, cultural aspect, cultural character and chronological attribution, and the new-discovered plentiful data enrich to a good extent our understanding of the contents of the Hemudu culture and have great importance to the study of the culture's developmental links and related problems.展开更多
