英文摘要	The aim of the present study is to investigate the difference between ITS sequences of Artemisia halodendron Turcz. from different habitat gradients in Horqin Sandy Land, with Artemisia depauperata Krasch. selected as the outgroup. Results indicate that the total length of A. halodendron ITS is 696 bp, the lengths of unaligned ITS-1 and ITS-2 sequences varied from 253 to 256 bp and 264 to 269 bp, respectively, and GC content of ITS-1 and ITS-2 sequences ranged from 54.02% to 54.77% and 56.75% to 58.64%, respectively. This indicates a high difference of length and composition of sequences in ITS-1 than ITS-2. The genetic identity between ITS sequences of A. halodendron from nine populations ranged from 85.7% to 99.7% which indicates some genetic differentiation between sequences. In the maximum parsimony (MP) tree, most ITS sequences from A. halodendron show two major clades: Clade I and Clade II, with Clade II older than Clade I. The order is subp4 subp1 subp2 subp3 subp8 subp6 subp7 subp9 subp5, and corresponding habitat order is: inter-dune lowlands semi-mobile dune mobile dune semi-fixed dune fixed dune. This indicates a close relation between the evolutionary processes of A. halodendron and desertification forming processes and ecological restoration processes of Horqin Sandy Land
