Chen Zuo-zhong, Huang De-hua and Zhang Hong-fang   

Abstract: The contents of N, P, K, Ca, S, Fe, Al, Si, Na, of 122 plant species in the XiLin River valley in Nei Monggol were studied. These results have shown as follows: 1. The contents of N, P. K, Ca, S, Fe, Al, Si, Na of 122 plants belong to three levels: N, K, Ca are 101-100(%) P, S, Si, Na are 100-10-1(%); Fe, A1 are 10-1-10-2(%). 2. The contents of chemical elements of 122 plants were divided into three levels (high, middle and low content). The range of the content and the number of plants in each level were obtained.

Key words: Typical steppe, Element contents
