【Abstract】 The Gurbantungut Sandy Desert in Northern Xinjiang occupies a transi-tional position between the Central-Asian and Kazakhstan Deserts in its floraas well as vegetation, yet has its unique characteristics. The vegetation of the sandy district of Gurbantungut consists mainly of9 communities and 3 congregations. Because of the differences in naturalconditions, flora and plant communities among different parts, the Gurbantun-gut may be subdivided into 3 phytogeographical subregions; Southwestern,Southeastern and Northern. In a detailed scheme of division of Asian deserts, the Jungar Basinincluding Gurbantungut may be divided as an independent phytogeographicalunit, parallel with Central-Asian, Kazakhstan and Middle-Asian Deserts.更多还原
