The Jiahu site is an early Neolithic settlement,dated to 9000～7800 BP and located in Henan Province.A systematic floatation work was carried out on the site during the 2001 excavation season.Abundant charred plant remains were recovered,including tubers such as lotus,nuts such as trapa,fruits such as grape,seeds such as wild soybean,and crops such as rice.Various quantitative measurements were made to compare the materials.All of the results show that rice was not significantly abundant in comparison with the other plant remains.Considering that extremely abundant fish bones were also found from the site,the authors come to the conclusion that the subsistence of the Jiahu people relied mainly on fishing,hunting and gathering,and agricultural products gained from rice farming and animal husbandry were only minor supplement to their diet.
