| 1 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |
| 2 | Recent high-resolution glaciochemical record from a Dasuopu firn core of middle Himalayas显示文摘A 16.8 m firn core of middle Himalayas was recovered on the col of Dasuopu glacier in August 2006,being 7000 m above sea level.A total of 317 samples were measured for stable oxygen isotope ratios(δ18O)and major ion concentrations(Na+,NH4+,K+,Mg2+,Ca2+,Cl?,SO42?,and NO3?).The firn core dating and seasonal partitioning were carried out based on the marked seasonal variations along the stable oxygen isotopes and crustal species(Ca2+,Mg2+)profiles.The multi-parameters and high-resolution glaciochemical data set of Dasuopu firn core recorded the detailed chemical characteristics of pre-cipitation in high-elevation region,middle Himalayas,since 1991 A.D.,which mainly originated from the crustal and anthropogenic sources,while the sea-salt contribution was minor.The seasonal variability of major ion concentrations was dominated by the seasonal alternation of the prevalent air mass,at-mospheric circulation situation and precipitation regime.Linear regression analysis indicated that most of the variance in annual ionic fluxes can be explained by a linear dependence on snow accumu-lation rate. | WANG PengLing YAO TanDong TIAN LiDe WU GuangJian LI Zhen YANG Wei | 2008 | Chinese Science Bulletin2008，53，3： | 4 |
| 3 | Seasonal variations of dust record in the Muztagata ice cores显示文摘Based on the oxygen isotope ratio and microparticle record in ice cores recovered at Mt. Muztagata, Eastern Pamirs, the seasonal variations of atmospheric dust have been reconstructed for the past four decades. High dust concentrations and coarser particle grains have the similar trend with oxygen iso- tope value. Our statistical results indicate that 50%―60% high dust concentration samples occur dur- ing the season with high oxygen isotope values (summer), while low dust storm frequency during spring and winter. Back-trajectory analysis shows that the air mass hitting Muztagata predominately came from West Asia (such as Iran-Afghanistan Plateau) and Central Asia, which are the main dust source area for Muztagata. Dust storms in those source areas most frequently occur during summer (from May to August), while frequent dust storm events in northern China mainly occur during spring (March to May). Regions in the path of Asian dust transport, such as in Japan, the North Pacific, and Greenland, also show high dust concentrations during spring (from March to May). Our results indicate that dust storms have different seasonality in different regions within Asia. | WU GuangJian YAO TanDong XU BaiQing TIAN LiDe LI Zhen DUAN KeQin | 2008 | Chinese Science Bulletin2008，53，16： | 3 |
| 4 | PHASE STRUCTURE OF W-DOPED NANO-TiO2 PRODUCED BY SOL-GEL METHOD显示文摘With Ti(OBu)4 as precursor, and HAc as complexing agent, pure and W-doped TiO2 gelatins were prepared by a sol-gel method. During the process of gel formation, metal ions were dispersed in the porous TiO2 matrix.Then, powders of nano-TiO2 and W-doped nano-TiO2 were prepared by drying, grinding and heat treatment at different temperatures. The grain size and structure of the samples, pure TiO2 and W-doped, and treated at different temperatures,were studied by X-ray diffraction (XRD), Beckman Coulter Sorption Analysis and TEM.Results showed that, with increasing temperature, the TiO2 transformed from anatase to rutile and the grain size increased. This transformation and grain growth of TiO2 could be retarded by doping with W. | Yucheng Wu Xiaoye Hu Ting Xie Guanghai Li Lide Zhang | 2005 | China Particuology2005，3，4： | 3 |

| 18 | Chernobyl nuclear accident revealed from the 7010 m Muztagata ice core record显示文摘The total activity variation with depth from a 41.6 m Muztagata ice core drilled at 7010 m, recorded not only the 1963 radioactive layer due to the thermonuclear test, but also clearly the radioactive peak released by the Chernobyl accident in 1986. This finding indicates that the Chernobyl nuclear accident was clearly recorded in alpine glaciers in the Pamirs of west China, and the layer can be potentially used for ice core dating in other high alpine glaciers in the surrounding regions. | TIAN LiDe YAO TanDong WU GuangJian LI Zhen XU BaiQing LI YueFang | 2007 | Chinese Science Bulletin2007，52，10： | 1 |
| 19 | A facile hydrothermal preparation and photoluminescence study of ZnO micro/nanostructures on Zn foils显示文摘ZnO micro/nanostructures with various morphologies were grown via hydrothermal etching of Zn foil.Controlling the reaction temperature and time,rod-like,pencil-like,tube-like and flowerlike ZnO micro/nanostructures could be prepared directly on the Zn foil surface at temperatures 100-180℃ with excellent reproducibility.X-ray diffraction patterns indicated that these ZnO micro/nanostructures were hexagonal.Possible mechanisms for the variation of morphology are discussed.Moreover,photoluminescence spectra of the as-grown samples revealed that all of them consist of UV emission band at around 392 nm. | WU MingZai LU XiangHua LIU YanMei MA YongQing SUN ZhaoQi LIU XianSong ZHANG LiDe | 2011 | Science China Chemistry2011，54，10： | 1 |
