为了解土壤颗粒与养分的相关性，指导区域合理施肥、减少养分流失、提高土地生产力，采用全国土壤污染源普查山东聊城市数据，建立相邻尺度的区域、土壤类型间颗粒与养分的相关性。结果表明：在研究区域整体、全部样本层面，土壤颗粒与土壤养分含量的相关系数均达极显著性水平，砂粒与养分呈负相关，粉、粘粒与养分为正相关。在分解为低等级的行政区域、土壤类型时，只有莘县、东阿县、冠县、高唐县，以及脱潮土、潮土亚类的颗粒组成与养分含量相关性和整体相同，对较大空间区域、高等级土壤类型颗粒组成与养分含量相关性贡献大，为理解土壤颗粒与养分相关性提供了新思路。

To explore the correlation between soil particle and nutrient content,guide rational regional fertilization,reduce nutrient loss and enhance soil productivity,by using the data of Liaocheng City from National Investigation of Soil Pollution Source,the relationship of correlation between soil particle and nutrient at neighbouring space and soil type scales was build.The results showed that there were significant positive correlation between soil silt and clay with nutrient,negative correlation between sand and nutrient at the whole study region space and soil type scale.At the lower space and soil subtype scale, the same correlation happened only in the administrative region of Shenxian,Dong′e,Guanxian,and Gaotang,as well as the soil subtype of cinnamon fluvo-aquic soil and fluvo-aquic soil,which contributed to the correlation of the whole.So,a new thinking for correlation between soil particle and nutrient was provided.
