| 摘 要： | 测定并分析了黄土高原沟壑区淳化县境内泥河沟流域不同土地利用方式下土壤养分含量，结果发现流域内有机质、磷素和氮素的含量不高，尤其是氮素缺乏，相对钾素含量比较丰富。对林草地与水平梯田、坡耕地等农田土壤养分的比较分析，发现林草地在改善土壤养分方面比耕地效果明显。

| Abstract: | Soil nutrients of different land using in gully region of the Loess Plateau is analyzed. The contents of nutrients,such as organic matter,P and N,were low.The content of N was very poor.The contents of K were higher than others.By comparing the nutrients,it is found that the contents of soil nutrient in forest-grass land were higher than in orchard land and agriculture land. |
