[Objective] In order to select excellent afforestation species for forest system oasis region of Ulan Buh sandy land

initial growth adaptability of poplar varieties in the oasis region of Ulan Buh sandy land was evaluated. [Methods] About 20 poplar varieties including Beikang

08 and Zhonglin series were introduced as research objects and the Xinjiang Populous that is the current main afforestation species were taken as a reference. The initial growth adaptability of these poplar species in the oasis region of Ulan Buh sandy land were comprehensively evaluated with systematic cluster analysis and multi-factor fuzzy comprehensive evaluation. [Results] The growth rate

ten varieties(08-01

etc.) are able to growth vigorously in the Ulan Buh sandy land and can serve as an alternative species for afforestation and plant resources reserves in this area

six varieties(Jing 6

etc.) were assessed at medium adaptability

other four varieties(Liaoning poplar

etc.) belong to poor adaptability group that are unable to grow normally in the Ulan Buh sandy land.
