| 1 | Seasonal variations of stable isotope in precipitation and moisture transport at Yushu,eastern Tibetan Plateau显示文摘Precipitation δ 18O at Yushu, eastern Tibetan Plateau, shows strong fluctuation and lack of clear seasonality. The seasonal pattern of precipitation stable isotope at Yushu is apparently different from either that of the southwest monsoon region to the south or that of the inland region to the north. This different seasonal pattern probably reflects the shift of different moisture sources. In this paper, we present the spatial comparison of the seasonal patterns of precipitation δ 18O, and calculate the moisture transport flux by using the NCAR/NCEP reanalysis data. This allows us to discuss the relation between moisture transport flux and precipitation δ 18O. This study shows that both the southwest monsoon from south and inland air mass transport from north affected the seasonal precipitation δ 18O at Yushu, eastern Tibetan Plateau. Southwest monsoon brings the main part of the moisture, but southwest transport flux is weaker than in the southern part of the Tibetan Plateau. However, contribution of the inland moisture from north or local evaporation moisture is enhanced. The combined effect is the strong fluctuation of summer precipitation δ 18O at Yushu and comparatively poor seasonality. | TIAN LiDe MA LingLong YU WuSheng LIU ZhongFang YIN ChangLiang ZHAO ZhongPing TANG Wei WANG Yu | 2008 | Science China Earth Sciences2008，51，8： | 9 |
| 2 | Analysis of Ecological Vulnerability of Grassland in Yushu of China Based on Landscape Pattern显示文摘[Purpose] It aims to study the situation of ecological vulnerability of grassland in Yushu.[Methods] Based on the field survey sampling spots on grassland of Yushu,interpretation has been conducted on grassland types on TM remote sensing image,and grassland degradation degree has been qualified.By using landscape indexes,ecological vulnerability analysis has been conducted on seven landscape types of natural grassland.[Result] The comprehensive index of ecological vulnerability of Yushu grassland is low,and moderately vulnerable area and above have taken up 99.91% of the total area.[Conclusion] Ecological vulnerability has been the largest hidden danger threatening ecological security of grasslands in the test area. | CHUN Mei(Grassland Station of Nangqian,Nangqian,Qinghai 815200,China) | 2012 | Journal of Landscape Research2012，4，7： | 0 |
