| 1 | Test of the uplift of Tibetan Plateau by FG5 absolute gravimeter at Lhasa station显示文摘The uplift of the Tibetan Plateau has been monitored by the FG5 absolute gravimeter, whose observing accuracy is as high as 1×10-8m/s2. The analysis of the gravity observation results at the Lhasa station in 1999 and 1993 shows that the gravity value has decreased by 12×10-8 m/s2, and it is confirmed that the Lhasa region is uplifting at a rate of 10 mm/a. | Weimin Zhang Yong Wang Houze Xu Chijun Zhang Xinghua Hao Ming Liu | 2001 | Chinese Science Bulletin2001,46,3: | 5 |
| 2 | Distribution of branched glycerol dialkyl glycerol tetraethers in soils on the Northeastern Qinghai-Tibetan Plateau and possible production by nitrite-reducing bacteria显示文摘Branched glycerol dialkyl glycerol tetraethers(b GDGTs) are ubiquitous and abundant in soils, but their sources remain elusive. Recent studies demonstrate that the distributions of b GDGTs are sensitive to various environmental factors. In an effort to understand how and to what extent soil moisture(expressed as soil water content(SWC) or mean annual precipitation(MAP), p H and temperature may impact the distribution of b GDGTs, and to shed more light on the biological sources of b GDGTs in cold and arid regions, we investigated the distribution of b GDGTs as well as bacterial 16 S r RNA gene and functional genes involved in the N cycle(including amo A, nir S and nir K) in 41 surface soil samples from around Lake Qinghai and east of Qaidam Basin on the Northeastern Qinghai-Tibetan Plateau. We found that lower soil moisture reduced the fractional concentrations of cyclic b GDGTs and thus the cyclisation ratio of branched tetraethers(CBT) index correlated negatively with SWC and MAP, suggesting that soil moisture is an important factor controlling b GDGT distributions in soils in this arid and semi-arid region. Two subgroups of b GDGTs were assigned on the basis of cluster analysis, and b GDGT indices behaved differently in the two groups, hinting at different biosynthetic mechanisms for b GDGTs under different environmental conditions. Real time PCR results showed that nir S and nir K genes correlated significantly with the concentration of b GDGTs, suggesting that the nir S- or nir K-encoding bacteria involved in denitrification might potentially be an additional biological source for soil b GDGTs(besides Acidobacteria). Moreover, our results also support the application of new indices based on 5-methyl b GDGTs and 6-methyl b GDGTs in reconstructing past temperature and p H variations in this region. | SUN ChiJun ZHANG ChuanLun LI Fu Yan WANG HuanYe LIU WeiGuo | 2016 | Science China Earth Sciences2016,59,9: | 3 |

| 6 | Refining geoid and vertical gradient of gravity anomaly显示文摘We have derived and tested several relations between geoid ( N) and quasi-geoid( ζ) with model validation. The elevation correction consists of the first-term ( Bouguer anomaly) and second-term ( vertical gradient of gravity anomaly) . The vertical gradient was obtained from direct measurement and terrain calculation. The test results demonstrated that the precision of geoid can reach centimeter-level in mountains less than 5000 meters high. | Zhang Chijun Bian Shaofeng Yi Zhourun Liu Lingtao Fang Jian | 2011 | Geodesy and Geodynamics2011,2,4: | 1 |

| 8 | Relation between Gravity Field Feature and Tectonics and Earthquakes in Taiwan and Its Adjacent Seas显示文摘Short wave gravity anomaly is correlated to sea floor topography in the gravity field of ×Taiwan and its adjacent seas. Gravity values of 20010-5ms-2 at Yushang and -×16010-5ms-2 at Liuqiu sea trench are respectively the maximum and minimum gravity values in this area. Bouguer gravity anomaly reflects not only Moho interface undulation, but also fault distribution. The inflexion of gradient belt of Bouguer gravity anomaly is a spot liable to earthquakes . Middle-long wave geoid is the best data to invert crustal thickness. We calculate crustal thickness by using geoid data, and the maximum value is 38km; the minimum value is 12km in Taiwan and its adjacent seas. | Zhang Chijun(张赤军) Fang Jian(方剑) | 2001 | Marine Science Bulletin2001,3,2: | 0 |
