Chinese Herbal Medicines 2015年第1期7卷 45-53页

作者： li-ping li Ben-gang Zhang Pei-gen xiao Zhao Zhang Yao-dong Qi xiao-jin li Guo-ping Wang Hai-tao liu Key Laboratory of Bioactive Substances and Resources Utilization of Chinese Herbal Medicine (Peking Union Medical College) Ministry of Education Institute of Medicinal Plant Development Chinese Academy of Medical Sciences Peking Union Medical College Xinjiang Institute of Chinese Materia Medica and Ethical Materia Medica

Objective To comprehensively map the distribution patterns of native medicinal plants of Xinjiang Uygur Autonomous Region, China; To find the environmental determinants and to give suggestions for the conservation planning of medicinal plants in Xinjiang region. Methods Firstly, we compiled the distribution data of native medicinal plants at a county level in Xinjiang region, including the source plants of Chinese Materia Medica （CMM）, Uygur Medicine （UM）, and Kazak Medicine （KM）; Secondly, we divided the distribution data into grid with a resolution of 0.1~ x 0.1~ and overlaid it on the topography and climate data in Arcgis 10.0; Finally, we analyzed the correlations of medicinal plant richness and environmental variables with ordinary least square （OLS） regressions and partial regressions. Results UM has more non-native species in Xinjiang region than KM. The species richness of medicinal plants is high in Altay Mountains, western Tianshan Mountains, and part of Kunlun Mountains. The richness of medicinal plants is highly correlated with the vascular plant species richness and climate, and further, the independent effects of vascular plant species richness are higher than the independent effects of climate. The whole plant, root ＆ rhizome, and seed ＆ fruit are more frequently used than stem and leaf for CMM in Xinjiang region. Conclusion The distribution patterns of medicinal plants are concordant with vascular plant species, which could be carefully considered in the conservation planning of this region. Taking full advantage of current nature reserves is a low-costing approach to the conservation of medicinal plants although they were not originally established for medicinal plant protection. Nevertheless, it is urgent to further study the distributions and protection status of medicinal plants in the nature reserves of Xinjiang region.

We theoretically investigate the spin resolved Friedel oscillation （FO） and quasiparticle interference （QPI） in graphene induced by an Anderson *** the impurity becomes magnetic,the resulted FO becomes spin dependent,which gives rise to a local magnetic moment oscillation with an envelop decaying as r-2in real space in the doping ***,at half filling,the electron density and local magnetic moment will not oscillate but decay as *** spin resolved FO has both sublattice and spin ***,the local magnetic moment decay at half filling only occurs at one sublattice of graphene,which is quite like the phenomenon observed in the STM experiment (***ález-Herrero et al.,Science 352,437 （2016）).We further give an analytic formula about such spin dependent FO based on the stationary phase ***,we study the interference of quasiparticles around the magnetic impurity by calculating the spin dependent Fourier-transformed local density of states （FT-LDOS）.Our work gives a comprehensive understanding about the local magnetic moment oscillation around an Anderson impurity on graphene.
