Rice Farming Of Longshan Period At The Zhaojiazhuang Site, Jiaozhou, Shandong

Preliminary achievements have been gained on the research of prehistoric rice farming in the Haidai region. It has been understood on the spatial distribution of carbonized rice grain, the harvest and the processing, with the previous archaeological finds. However, there are still many questions unresolved on the rice farming, for example, how to find the paddy field, what kind of harvest tools had been used, how many types of rice were planted, when and how the rice farming technology was spread to the Korea peninsula and Japan, etc. My research uses the data from systemic flotation and phytolith samples of the Zhaojiazhuang site, Shandong, and tries to propose my own understanding to the above question. The thesis is divided into six parts.Part one introduces previous research results of rice farming in the Haidai region and ongoing questions, also introduces the research aim and methods.Part two reviews the modern natural environment, the archaeology background and cultural relics of the Zhaojiazhuang site.Part three presents research materials of my research, which includes soil samples from living region and cropping region, as well as the stone implements from living region of the Zhaojiazhuang site. The methods of flotation and phytolith analysis that are used in my research are illustrated in this part.Part four is the results of flotation and phytolith from the Zhaojiazhuang site. We find plentiful plant remains. A lot of carbonized seeds are found in living region. Also lots of phytoliths of rice are found in cropping region and on the stone implements.Part five discusses the rice farming of the Zhaojiazhuang site. Firstly, based on the analysis results, it can be concluded that rice farming was important in Zhaojiazhuang site in the Longshan period. The study also suggests the culture and environment background of the appearance of rice farming. Secondly, through the analysis of landform and soil samples of the Zhaojiazhuang site, we are sure that paddy field was existed in the site.Part six is the conclusion. There are some preliminary conclusions on the archaeo-botanical research of crop species, the status of rice farming in the site, paddy field cropping, the function of stone implements, and the way of harvest.
