摘　　要：以银川市西夏区贺兰山东麓张裕摩塞尔十五世酒庄葡萄园、银川市园林场、镇北堡和芦花台园林场等4处葡萄种植区作为研究区,在分析土壤C、N、P化学计量特征的基础上,利用Pearson相关分析、单因素方差分析进行统计分析。结果显示:1)贺兰山东麓葡萄产区土壤C、N、P含量整体水平不高,分别对应于中国土壤C、N、P含量等级的第五级、第五级、第三级,处于全国中等较低水平。2)贺兰山东麓葡萄产区土壤C/N为11.199,与全国平均值吻合;C/P为11.459,远低于全国平均值;N/P为1.065,低于全国平均水平。研究区土壤P的有效性高,N相对较少,要注重适当添加。3)研究区内不同区域间C、N、P含量差异明显。银川市园林场和芦花台园林场土壤养分含量较高,而镇北堡和张裕摩塞尔十五世酒庄葡萄园土壤养分含量偏低。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.
