Abstract: In this paper, the contents of 13 chemical elements (N,P,K,Ca,Mg, Mn, Zn,Cu,Co,Cr,Ni,Cd,Pb) in different plant types of Natural Grassland Reserve of Wutai Mountain were studied.The contents of 13 chemical elements in various plant species were great difference.The average contents of N and Ca were higher than 10g/kg; P, Mg, and K ranged between 1 and 8 g/kg, Mn, Zn, Cu and Cr between 10 and 100 mg/kg,Ni and Pb from 1 to 9 mg/kg; Co and Cd were less than 1 mg/kg.The plants in studied area were of high nutrition levels, which were able to meet the ha requirements of the animal, particularly the plants in the subalpine meadow were highly valuable for feeding animal.
