| 摘 要： | 通过土壤样品采集和实验室分析,系统研究鄂尔多斯市公园绿地土壤的化学特性及养分丰缺状况,包括pH值、有机质、全氮、全磷以及有效氮、磷、钾,分析养分因子之间的相关性,评价公园绿地土壤的肥力状况,揭示出鄂尔多斯市公园绿地土壤存在的问题：土壤pH值偏高,其中85.7%的土壤呈强碱性,其余呈碱性;多数土壤有机质、全氮、全磷、碱解氮、有效磷、速效钾含量处于缺乏及以下水平;土壤pH值与有机质、速效钾分别显著和极显著负相关;有机质与其他养分因子之间均极显著相关。

| Abstract: | Through soil sample collection and laboratory analysis, the article researched systematically on chemical characteristics and its nutrient abundant conditions of the green soil in parks of Ordos, including pH value, organic matter, total nitrogen, total phosphorus and available nitrogen, phosphorus and kalium, and analyzed the correlation between these nutrient factors, evaluated the soil fertility quality of green land in park. Finally the paper revealed the problems of park green land of Ordos：Soil pH values were high, 85.7%were strong alkaline soil, others were alkaline soil;organic matter, total nitrogen, total phosphorus, alkali-hydrolyzale nitrogen, available phosphorus and available kalium of most soils were in the lack level and below. Soil pH value had a negative correlation relationship with organic matter and available kalium, and soil organic matter had a significant correlation with each nutrient factors. |
