摘要：

为了剖析平原潮土区1982年和2009年2期土壤有机质的时空变化情况，以期提高耕地利用效率和实现农业可持续发展，笔者采用统计学、地统计学和地理信息系统（GIS）相结合的方法，研究了河南省民权县土壤有机质含量（SOM）的时空变异特征。结果表明：空间上，1982年土壤有机质含量自东向西逐渐降低；与1982年相比，2009年的土壤有机质含量普遍增加1个级别，增加最多的区域分布在研究区域的中部。时间上，1982—2009年，随着施肥量的增加、施肥水平的提高，种植结构的合理化和水利资源利用率的提高，整个研究区域土壤有机质含量普遍增加。有机质含量平均值从6.23 g/kg增加到13.19 g/kg，增加了111.7%。通过2个时期土壤分析得到的结果对合理施肥、农业种植区划具有指导有意义。

Abstract:

In order to analyze the spatio-temporal variability of soil organic matter about alluvial soil in plain area from 1982 to 2009，enhance the cultivated land utilization efficiency, and realize agricultural sustainable development, the author researched the soil organic matter of Minquan county in Henan Province by using statistics, geostatistics and geographical information system (GIS) .The results judging from the space showed that the content of soil organic matter gradually reduced from east to west in 1982, and the content of soil organic matter generally rose to a level in 2009 compared with the 1982, and the most raising place lied in the centre of the studying area. Judging from the time, along with the improvement of fertilization, the rationalization of planting structure, and the increase of water utilization ratio, the soil organic matter content of this study area generally increased from 1982 to 2009. The average value of the soil organic matter content increased from 6.23 g/kg to 13.19 g/kg, increasing by 111.7%. The results by analyzing the change of soil organic matter content in two different period, could provide guidance to fertilize and plan agricultural structure properly.
