Surfer软件在膜孔灌溉土壤含水率绘制中的应用

摘要

利用Surfer软件可以绘制各类等值线图,通过膜孔灌溉试验研究,以入渗时间分别为20 m in、79 m in和135 m in的膜孔入渗数据为例,采用Surfer软件绘制等值线图。实践证明软件的应用不仅能提高工作效率,而且也能减少由于人为原因造成的误差,提高水量分布图的质量。具有一定的应用和推广意义。%Surfer software package can be used to draw various isograms.The article is based on film hole irrigation test,the film hole infiltration data of 20min,79min and 135min were taken as a case to introduce the method and steps how to plot isoline with Surfer.The application of software not only improves work efficiency,but also decreases manual error and improves quality of percentage of moisture isoline maps.These research have laid a foundation for further research of film hole infiltration.
