The analysis based on the household survey in 2013 shows that the targeting accuracy is not high based on the standard of income and the accuracy is higher based on the standard of multidimensional poverty index. But the latter still has a low coverage rate. To gradually achieve integration of the rural poverty line and the rural subsistence allowance line, standards applied to identifying households entitled to subsistence allowances should be changed from the standard of income to multidimensional poverty indexes. A unified standard of subsistence allowances and a unified method for identifying related households should be developed. At the same time, coverage and funding of subsistence allowances should be extended and increased to better meet people's basic needs.展开更多

The studies on CeO2-ZrO2-V2O5-CuO mixed oxides which were prepared by coprecipitation, show that the doping of V^5＋ and Cu^2＋ in CeO2-ZrO2 mixed oxides can enhance the catalytic activity and thermal stability of coating materials. Moreover, different additives were doped in slurries of γ-Al2O3 to investigate the influence of additives on oxidation activity of catalysts. The mixture of ceria-zirconia, alkali metals and other rare earths acting as additives exhibits promotion effect on oxidation activity by optimizing the distribution of oxygen on the surface and in the bulk of ceria species. This mentioned mixture was mixed with γ-Al2O3 and a newly proposed active component to prepare a new catalyst. Afterward, the influence of thermal treatment on the new catalyst were investigated by calcinations at 500, 650, 750, 800, 850 and 900 ℃ for 2 h. The light-off curves of CO and HC show that after being treated at 650 - 750 ℃, catalysts present the best activity. XRD patterns show that ceria and zirconia species in the newly proposed active component form a phase of extra CeO2-ZrO2 mixed oxides on the surface of catalysts after the thermal treatment at 750 ℃, which has practical value for improving the preparation process and promoting the catalytic properties. Moreover, XPS resuits imply the existence of Ce1-xPdxO2-σ and Ce1- xPtxO2-σ on the surface of these treated samples, which may show influence on the catalytic activities.展开更多

On the one hand, the protection of human rights is the purpose of economic development, i.e., promoting economic and social rights through economic development, and then creating conditions for the realization of civil and political fights. On the other hand, the protection of human rights is a means to economic development, and only through the protection of human fights, can sustained and healthy economic development be realized. The economic development model of China since 1978, for quite a long period of time, is suitable for subsistence-based development. However, it also has created risks of economic failure and political legitimacy crises. So it is necessary to adopt a scientific development model which values human rights.展开更多

Therefore, we analyze archaeobotanical, zooarchaeological and carbon isotopic data from late Neolithic and Bronze Age sites in agricultural, pastoral, and agro-pastoral regions of north China. Our results demonstrate human subsistence strategies transformed at different speeds in these three geographic areas after wheat, barley, and sheep, goats, and cattle were introduced into north China. Introduced crops and livestock dominated human livelihoods in pastoral regions and became important subsistence in areas above ~1500 m a.s.l. in agro-pastoral regions after ~3600 BP. In agricultural regions, indigenous millet crops were the most important subsistence throughout 6000– 2200 BP, but wheat use increased significantly around 2700 BP. Our study suggests that the introduction of new crops and herbivorous livestock related to the prehistoric trans-Eurasian exchange, and their adaptive advantage in high-cold environments might have rapidly facilitated human adaptability and social development in pastoral regions and northwest margin of agro-pastoral regions during the Bronze Age.展开更多

文摘As the crossroads of prehistoric cultures,the Beijing region is an important area for studying the exchange of prehistoric culture and the spread of millet agriculture.Although millet remains have been found in the Donghulin site during the Early Neolithic Age,there is little millet remains during the Middle and Late Neolithic Age,so there is a gap of approximately2,000 years since the time of the Donghulin site.The Shangzhai site is located in the Pinggu Basin in eastern Beijing,and it has a large time span with sequential strata;however,there are few large animals and plant remains found at this site,thus the subsistence strategy of ancient people remains unclear.In this study,the absorbed lipids of pottery sherds unearthed in the Neolithic cultural layer of the Shangzhai site were extracted and analysed.The results show that these potteries were used to process millet,the meat of terrestrial non-ruminants and wild ruminants,and dairy of wild ruminants,providing new insights for the subsistence strategy and the development of millet agriculture in the Middle and Late Neolithic Age of Beijing.In addition,the food processing in pottery may be an internal heating method,such as stone boiling.
文摘Historically, economic development and human fights go hand in hand. On the one hand, the protection of human rights is the purpose of economic development, i.e., promoting economic and social rights through economic development, and then creating conditions for the realization of civil and political fights. On the other hand, the protection of human rights is a means to economic development, and only through the protection of human fights, can sustained and healthy economic development be realized. The economic development model of China since 1978, for quite a long period of time, is suitable for subsistence-based development. However, it also has created risks of economic failure and political legitimacy crises. So it is necessary to adopt a scientific development model which values human rights.

文摘Significant spatiotemporal variation in human livelihood patterns and its relationship to trans-Eurasian exchange and climate change in north China during the late Neolithic and Bronze Age, has been intensively studied in recent years, but the comprehensive influence of natural and social factors on this variation is not well understood. Therefore, we analyze archaeobotanical, zooarchaeological and carbon isotopic data from late Neolithic and Bronze Age sites in agricultural, pastoral, and agro-pastoral regions of north China. Our results demonstrate human subsistence strategies transformed at different speeds in these three geographic areas after wheat, barley, and sheep, goats, and cattle were introduced into north China. Introduced crops and livestock dominated human livelihoods in pastoral regions and became important subsistence in areas above ~1500 m a.s.l. in agro-pastoral regions after ~3600 BP. In agricultural regions, indigenous millet crops were the most important subsistence throughout 6000– 2200 BP, but wheat use increased significantly around 2700 BP. Our study suggests that the introduction of new crops and herbivorous livestock related to the prehistoric trans-Eurasian exchange, and their adaptive advantage in high-cold environments might have rapidly facilitated human adaptability and social development in pastoral regions and northwest margin of agro-pastoral regions during the Bronze Age.
