The temperature data from 3 meteorological stations (Kashi, Ruoqiang, and Hotan) in the South of Tarim River Basin (STRB) during 1964-2011 were analyzed by Mann-Kendall test and correlation analysis. The results from Mann-Kendall test show that the surface temperature (ST), 850 hPa temperature (T850), and 700 hPa temperature (T700) exhibited upward trends, while 300 hPa temperature (T300) revea...
To evaluate the genetic diversity of the Xinjiang Tarim red deer (Cervus elaphus yarkandensis) population, we analyzed the frequencies of microsatellite alleles. Samples were collected from 3 isolated populations in Xaya, Lopnur and Qarqan of Xinjiang. Although 10 microsatellite loci were examined, alleles of 133 to 190 base-pairs were detected for only 3 loci: BM5004, BM4208 and BM888. The ave...
Five Calligonum species endemic to the Tarim Basin - C. roborowskii, C. kuerlese, C. juoqiangense,C. yengisaricum, and C. taklimakanense - were compared using 14 morphological characteristics and nrDNA ITS and cpDNA trnL-F molecular data. Intraspecific and interspecific morphological variation was uncovered, with variation between species significant for most characteristics. Based on Euclidean...
We studied a suite of 40 oils and extracts of purported source rocks from the Tarim basin in NW China. The main group of oils comes from Tazhong and Tabei wells, which sample the largest known petroleum accumulations in the basin. These oils can be statistically correlated with extracts of Ordovician rocks based upon high relative concentrations of 24-isopropylcholestanes and low relative conce...
As the largest inland river basin of China, Tarim River Basin (TRB), known for its various natural resources and fragile environment, has an increased risk ecological crisis due to intensive exploitation utilization water land resources. Since Ecological Water Diversion Project (EWDP), which was implemented in 2001 save endangered desert vegetation, there been growing evidence improvement local...
As an important agricultural and gathering area in arid inland areas of China, the ecological environments oasis are more sensitive to regional climate change human activities. This paper investigates dynamic evolution oases Tarim River basin (TRB) quantitatively evaluates security via a remote sensing index (RSEI) net primary productivity (NPP) through Carnegie–Ames–Stanford approach (CASA) fr...
Abstract. We collected GPS data from the southern Tarim basin, the Qaidam basin, and the western Kunlun Shan region between 1993 and 1998 to determine crustal deformation along the Altyn Tagh fault system at the northern margin of the Tibetan plateau. We conclude from these data that the Altyn Tagh is a left-lateral strike slip fault with a current slip rate of 9 mm/yr, in sharp contrast with g...
