对一块面积为１ ｈｍ ２ 麦田内的９８ 个观测点取样分析，测定了代表不同土壤含水率水平下的两个时期土壤表层和底层的 Ｎ Ｈ４ Ｎ、 Ｎ Ｏ３ Ｎ、 Ｏｌｓｅｎ Ｐ、表层有机质和全氮等养分。应用地统计学的方法对所取的数据进行了分析，结果表明底层土壤的 Ｎ Ｈ４ Ｎ、表层土壤的有机质服从正态分布；其余养分基本上服从对数正态分布；按一定的精度和置信水平确定了合理的取样数目。通过半方差函数分析，发现这些养分在一定范围内存在空间相关性；采用 Ｋｒｉｇｉｎｇ 方法对未测点进行了估值，绘制了等值线图，并对两个时期的养分动态的空间变异进行了初步分析。该成果可用于提高氮肥利用率和精确农业（施肥）的研究和实践。
A total of 98 observation points in a wheat field of 1 hm 2 were sampled and analyzed. N H 4N, N O 3N, OlsenP on the surface and bottom of the soil were measured at different soil moisture levels. Organic matter and total nitrogen and other nutrients. According to the geostatistics method, the data were analyzed. The results showed that the N H4N in the bottom soil and the organic matter in the surface soil obeyed the normal distribution. The remaining nutrients basically obeyed the logarithmic normal distribution. According to certain accuracy and Confidence levels determine the reasonable number of samples. Through semi-variance function analysis, it was found that there was spatial correlation among these nutrients in a certain range. Kriging method was used to estimate the unmeasured points and the contour map was drawn. The spatial variability of nutrient dynamics in two periods initial analysis. The results can be used to improve nitrogen fertilizer utilization and precision agriculture (fertilization) research and practice.
