The results show that the pollen influx has a distinct change. During 2.6 - 2.0 Ma B.P., the average value of pollen influx increased evidently compared with that of 3.0 - 2.6 Ma B.P. It shows that the sea level of SCS dropped dramatically around 2.6 Ma B.P., corresponding to the formation of the Northern Hemisphere ice-sheets and the enhancement of the East Asian Monsoon. The pollen influx variations reflect the glacial-interglacial cycles corresponding with the deep-sea oxygen isotope curve and indicate that the sea level of SCS rose and dropped many times after 2.6 Ma B.P. The spectrum analysis results of pollen influx show that there are cycles at 0.1Ma (eccentricity) and 46.9 ka (obliquity) during 3.0 - 2.0 Ma B.P.展开更多

According to requirements of Notice of the General Office of the People's Government of Anhui Province on Implementing the Confirmation and Registration of Ownership of Rural Collective Land,in order to integrate urban and rural development and safeguard the rights and interests of farmers,since January 2010,Ma'anshan Municipal Government has made an overall deployment in the whole city to carry out the confirmation and registration of rural collective land. However,complex property situation of the collective land and the problems of existing registration system have brought about many problems. Through the research and analysis,we came up with recommendations for improving the registration of rural collective land.展开更多

F index, G index and G-F index of beetle communities in five nature reserves were analyzed to calculate the similarity coefficient C between these five na- ture reserves. According to the results, beetle communities exhibited high dissimilarity between Jiuzhaigou and Xiaozhaizigou, Caopo and Jiuzhaigou, Caopo and Xiaozhaizigou, Ma'anshan and Xiaozhaizigou, Ma'anshan and Jiuzhaigou, Baihe and Xiaozhaizigou, Baihe and Caopo, Baihe and Ma'anshan; beetle communities exhibited moderate dissimilarity between Ma'anshan and Caopo, Baihe and Jiuzhaigou.展开更多

In this research, the bone assemblages are quantified based on elements of MNI, MNE, and MAU. Then bone surface modifications and skeletal element profiles of the bone assemblages are studied to understand shlepping behaviors and reveal the technique of disarticulating and defleshing the animals’ bodies, etc. Based on the analyses of bone assemblages and the comparative study with the ethnoarchaeological as well as experimental data, it is assumed that later hominids at the site made fuller use of the game animals than the earlier hominids. Incorporating the lines of evidence from chronological dating, paleoenvironment, and polished bone tools between the two cultural layers, here we propose three hypotheses suggesting that the changes of environment, the migrations of the hominids from the North, or the demographic pulses may cause such a behavioral difference. However, it is yet to be determined which hypothesis can better explain the changes.展开更多
