The contents of soil organic matter, total N, total P and total K were monitored. Geostatistics method and Moran’s I of spatial autocorrelation method were used to analyze the spatial features of soil nutrients. Study shows that, the spatial heterogeneity of soil nutrients’ content changes mainly by random factors, for example, human activities such as irrigation, fertilization, cultivation measures, cropping systems, etc. The spatial correlation of the soil nutrients’ content is very weak. On the whole, there is an obvious spatial distribution of the four soil nutrients which gradually declines from the eastern and southern to the western and northern part of Liaocheng city. In the scope of the 40km, Moran's I coefficients of four kinds of soil nutrients are positive which shows a positive spatial correlation. The response of organic matter on the scale is more sensitive than that of other three nutrients. The change of Moran's I of total N and total P is similar, but Moran's I coefficient of total K outside the scope of 64km performs the volatility in the vicinity of 0, which may be related to the local agricultural activities., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null,

runingTitle=null, highlight=null, articleAbstract=按8 km×8 km网格将聊城市耕地分为136个采样点，调查土壤有机质、全氮、全磷、全钾4种土壤养分的含量。采用地统计分析与空间自相关的Moran I系数分析土壤养分的空间变异规律。研究表明，土壤耕层养分含量变化的空间异质性主要由随机性因素如灌溉、施肥、耕作措施、种植制度等人为活动引起，空间相关性很弱。4种土壤养分存在明显的空间分布规律，总体上呈现由东、南部向西、北部逐渐递减的空间分布格局。在40 km范围内，4种土壤养分的Moran I系数均为正值，表现出在此范围内空间呈正相关。有机质对尺度的响应较其他3种养分更为敏感，全氮和全磷的Moran I变化趋势类似，而全钾在64 km范围之外的Moran I系数表现出在0值附近的波动性，可能与地方农业活动有关。, authors=张金萍^1,2，张保华²，秦耀辰¹, authorsList=张金萍;张保华;秦耀辰, authorCompany=1. 河南大学环境与规划学院，河南开封
