Abstract: In the present study, vineyards, i.e. Changyu vineyard, Yinchuan Forest Farm, Zhenbeibu, and Luhuatai Farm, located in the east piedmont of Helan Mountains in Xixia District, Yinchuan City, were selected as study areas. Based on the analysis of soil C, N, P stoichiometric characteristics, Pearson correlation analysis and one-way ANOVA were introduced for further analysis. It was shown that the overall C, N, P content was relatively low for the national average level. Specifically, soil C, N, P content was within national Level 5, Level 5 and Level 3, respectively. Soil C/N was 11.199, which was in accordance with the national average value. Soil C/P was 11.459, which was far below the national average value. Soil N/P was 1.065, which was below the national average value. Soil P content was relatively high in the study area, while N content was low. Soil C, N, P content differed within different farms. The soil nutrient contents in Yinchuan Forest Farm and Luhuatai Farm were relatively higher than those in Zhenbeibu and Changyu vineyard.
