Suitability Evaluation of Afforestation Tree Species for Desertification Control in Changji Prefecture of Xinjiang
In order to screen out the afforestation tree species suitable for desertification control,this study evaluated the suitability of desertification control tree species in the north of Changji Hui Autonomous Prefecture of Xinjiang.Based on the suitability of land and trees,the investigation and research were carried out from four aspects:including ecological adaptability,ecological function,economy and ornamental value.The results showed as the following three aspects.(1)It is recommended to select Haloxylon ammodendron,Calligonum mongolicum,Tamarix ramosis-sima,Populus euphratica,Lycium ruthenicum and Hippophae rhamnoides as the preferred tree species in the a-bove-moderate desertification area,and Fraxinuschinensis,Ulmus pumila,Populus alba var.pyramidalis and Ly-cium barbarum as the preferred tree species in the mild desertification area.(2)It is recommended to choose the top wind and sand fixation tree species,including Haloxylon ammodendron.Calligonum mongolicum and Tamarix ramosissima,which have strong ecological adaptability and excellent wind and sand fixation performance.It is rec-ommended to choose Haloxylon ammodendron,Tamarix ramosissima,Calligonum mongolicum and Caragana korshinskiifor soil and water conservation forest,and to choose Fraxinus chinensis,Ulmus pumila,Populus alba var.pyramidalis and Haloxylon ammodendron for farmland shelterbelt forest.(3)It is suggested to choose Haloxylon ammodendron inoculated with Cistanche deserticola,Lycium barbarum and Hippophae rhamnoides as the main tree species for economic forest,and Lycium ruthenicum,Xanthoceras sorbifolium and Hedysarum scopari-um can be used as the tree species for experimental promotion.
