Liu Jiaqiong;Qiu Guoyu;Shi Qinghui;Li Fengqin(Shapotou Desert Experiment and Research Station, Institute of Eesert Research, Academia Sinica,Lanzhou 730000).  

he drought-resistances of 16 representative sand-fixing plant species in the Taklamakan Desert area are analysed by comprehensive evaluation method,and the salt-tolerances of 6 plant species are observed through pot experiment irrigated with different salt concentration water.The 16 drought-resistant plant species can be ranked by their resistance to drought as:Tamarix hohenackeriHaloxylon ammodendronT. austromon-golicaH. persicum, Caragana korshinskii, Artemisia arenaria, Calligonum leucoladum,C. rubicundumC.angustifoliaHalimodendron holodendronAtraphaxis pungens, C. roborovskyiPopulus euphraticaElaeagnus angustifoliaPopulus simonii; while the 6 salt-tolerant species can be ranked as:Tamarix hispidaT. ramosissimaNitraria sibiricaHaloxylan ammodendronHalimodendron haloden-dronAmmodendron argenteum. The habitat adaptability of different sand-fixing plants are also discussed.
