今年是中国共产党成立90周年,也是辛亥革命爆发100周年,这两件关系中国命运的大事相隔10年,看似巧合,其实有着必然的联系。这是因为,辛亥革命要通过资本主义道路使中华民族复兴的路没有走通,所以使选择社会主义道路的中国共产党登上了复兴中华民族大业的历史舞台。近一个世纪的历史证明,中国共产党为中华民族复兴提供了根本的政治前提,抓住了难得的发展机遇,创造了良好的内外环境,继承并发扬光大了辛亥革命的未竟事业,使中华民族伟大复兴正在一步步变成现实。 相似文献

Understanding how to live successfully within our environment is among the most pressing challenges facing contemporary society. This paper probes the problem based on comparative analysis and discusses the relationship between the spatial–temporal distribution of the Neolithic cultural sites and the geographic context in the Hanjiang River Basin in the south of Shaanxi Province, China. Archaeological studies have identified 175 Neolithic cultural sites in the study area, with a sequence of Laoguantai (14C age 8–7 ka BP), Yangshao (14C age 7–5 ka BP) and the late period of the Neolithic Age (14C age 5–4 ka BP). The total number of archaeological sites, the distribution area and the density all showed an early ascending and later descending trend, but the proportion of the number of archaeological sites in the study area to the corresponding value of the entire Shaanxi Province declined sharply. Spatially, these sites were concentrated on the terraces of the Hanjiang River and its main tributaries with an altitude of 400–800 m. Multiple data were integrated to clarify the critical effects of tectonic and geomorphologic conditions on the distribution of the Neolithic sites. Further comparisons revealed the correlation of Holocene climate change and environmental evolution with the Neolithic cultural succession in the study area that ameliorated conditions to generally promote the development of the primitive culture while degeneration coincided with the culture's transition or interruption. The discussion on the origin of the primitive culture and the temporal–spatial distribution corresponding to the regional culture differentiation sheds light on the complex and dynamic human–nature interaction system during the Neolithic Age, thus emphasising the wider field-based investigation and high-resolution reconstruction works of the palaeoclimate and palaeoenvironment in the future. 相似文献

Yuan, D.X., Zhang, Y.C., Zhang, Y.J., Zhu, T.X. & Shen, S.Z., 2014. First records of Wuchiapingian (Late Permian) conodonts in the Xainza area, Lhasa Block, Tibet, and their palaeobiogeographic implications. Alcheringa 38, 546–556. ISSN 0311-5518.Conodonts are among the best fossil groups to provide high-resolution biostratigraphic correlation and resolve the palaeobiogeographic evolution of the Permian. However, they have been rarely reported from the Lhasa Block in Tibet. Here we report the first discovery of Wuchiapingian (early Lopingian) conodonts from the Xiala Formation in the Lhasa Block, Tibet. This conodont fauna includes two genera and three species (Clarkina liangshanensis, C. orientalis, Iranognathus sp.). The conodont fauna indicates that the Xiala Formation previously assigned to the Guadalupian actually ranges from late Kungurian to late Wuchiapingian. The existence of the late Wuchiapingian conodont species Clarkina orientalis and C. liangshanensis in the Lhasa Block provides additional data to support the viewpoint that this block probably had been in a warm-water regime during the Wuchiapingian (Lopingian).Dong-Xun Yuan [yuanzi55@163. com], School of Earth Sciences and Engineering, Nanjing University, 22 Hankou Road, Nanjing, 210093, PR China and State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing, 210008, PR China; Yi-Chun Zhang [yczhang@nigpas. ac. cn] and Shu-Zhong Shen [szshen@nigpas. ac. cn] (corresponding author), State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing, 210008, PR China; Yu-Jie Zhang [zebiac@163. com] and Tong-Xing Zhu [ztongxing88@yahoo. com. cn], Chengdu Center, China Geological Survey, 2 Renming Road North, Chengdu, 610081, PR China.

日本对海南岛调查之评述 总被引:1,自引:1,他引:0
长期以来,学界关于抗战时期海南岛问题的研究,主要集中于海南抗战、日军暴行和日本资源掠夺等领域,对日本在海南岛调查活动的研究则鲜有涉及,笔者根据日本投降时残留于金陵大学的部分资料和台湾总督府外事部相关资料,撰成此文,拟就日本近代对海南岛调查之动机、调查之机构、调查之分期、调查之内容等作一综合性探讨,以期引起学界埘此问题的关注。 相似文献
