| 1 | Foliar δ^(13)C and δ^(15)N values of C_3 plants in the Ethiopia Rift Valley and their environmental controls显示文摘The foliar C and N stable isotopic compositions(δ 13C and δ 15N) and the relationships between these compositions and environmental factors of C3 plants in the Ethiopia Rift Valley were investigated. There were three distribution patterns for foliar δ 13C with mean values of ?26.7‰±0.4‰,?29.7‰± 0.6‰,and ?26.9‰± 1.2‰ in cold-moist,temperate-moist,and arid-hot environments,respectively. The δ 15N values ranged from ?1.4‰± 1.7‰ to 14.3‰± 0.1‰,with higher values under arid-hot conditions and the lowest values in plants growing at higher altitudes under cold-moist conditions. A strong negative relationship between mean annual precipitation and δ 15N explained more than half of the observed variation in the δ 15N values(r2 = 0.54,P < 0.001);a modest positive relationship was also found between δ 15N and tem-perature(r2 = 0.32,P < 0.01). A weakly positive relationship existed between δ 13C and temperature,and changes in δ 13C values with precipitation and altitude followed quadratic curves. This suggests a shift in the effects of water and heat conditions caused by altitude on carbon isotopic discrimination. | LIU XiaoHong ZHAO LiangJu GASAW Menassie GAO DengYi QIN DaHe REN JiaWen | 2007 | Chinese Science Bulletin2007，52，9： | 12 |
| 2 | Arctic sea ice bordering on the North Atlantic and inter-annual climate variations显示文摘Variations of winter Arctic sea ice bordering on the North Atlantic are closely related to climate variations in the same region. When winter North Atlantic Oscillation (NAO) index is positive (negative) anomaly phase, Icelandic Low is obviously deepened and shifts northwards (southwards). Simultaneously, the Subtropical High over the North Atlantic is also intensified, and moves northwards (southwards). Those anomalies strengthen (weaken) westerly between Icelandic Low and the Subtropical High, and further result in positive (negative) sea surface temperature (SST) anomalies in the mid-latitude of the North Atlantic, and increase (decrease) the warm water transportation from the mid-latitude to the Barents Sea, which causes positive (negative) mixed-layer water temperature anomalies in the south part of the Barents Sea. Moreover, the distribution of anomaly air temperature clearly demonstrates warming (cooling) in northern Europe and the subarctic regions (including the Barents Sea) and cooling | Bingyi Wu Ronghui Huang Dengyi Gao | 2001 | Chinese Science Bulletin2001，46，2： | 4 |

| 8 | Holy Mountain of Qomolangmo显示文摘Qomolangmo is the 3rd Goddess in the eyes of the Tibetans, and since 1966 I have had the chance to stay there on eight occasions for a total of eight years. During this period, I was nurtured by her 'milk', breathed the fresh air, and enjoyed the hada (referring to 'flag clouds' there) that the mountain hoisted.Qomolangmo is the least contaminated place on earth.
