Mean cold-resistance index of 89 foreign trees in Wuwei city was determined by using standards for grade of cold- resistance of trees. Result shows that there are 46 kinds of cold-resistactant species in Wuwei city, more cold-resistactant species being 34 kinds;the rest is non-cold-resistant species. Quantitative indicators of cold-resistance for tree species se- lection were put forward.
