Abstract:: Populus euphratica forest is the only arbor species of constructive species in arid desert regions.In recent decades,due to people’s unreasonable use of Populus euphratica forest,the area of it has decreased greatly.Based on the background of typical area of the southern margin of the Tarim basin as well as the economic and social conditions of Hotan county,this thesis is focused on the ecological functions of Populus euphratica forest.It is intended to study the key factors and mechanism that affecting the growth of Populus euphratica forest at the micro level.Market valuation method and shadow engineering method are adopted to measure its ecosystem service function value.The results indicated that the backward economic and social conditions of Hotan County have intensified the vulnerability of its ecology,that light,temperature,soil,salt and hydrology have great influence on the growth of Populus euphratica forest,and that Populus euphratica forest plays an important role in reducing the dust and improving ecological environment,with its indirect economic value much higher than that of standing timber.
