| 摘 要： | 土壤水分的空间分布规律是灌溉决策中必须要考虑的重要因素 ,而如何确定测定土壤含水量观测点的位置和间距是影响灌溉决策精度的关键。本文通过对膜孔灌溉棉田土壤水分空间分布特性的研究 ,利用统计学分析方法 ,绘出了土壤水分的半方差图和等值线图。半方差图和等值线图对在灌溉决策系统中如何确定土壤水分观测点的位置和间距具有一定的指导意义。

| Abstract: | The space distribution rule of soil water is a most important factor in irrigation decision making. Position and distance of the observation spots for soil moisture measuring are the key factors impacted the precision of calculation. The space distribution rule of soil water under irrigation on plastic membrane in the cotton field is studied. Using statistics analysis method, the semi-variance graphic and isolines map of soil water are drawn up. These 2 graphics are useful to decide the observation spots of soil water measuring in the field. |
