| The field calibration of neutron probe in the soil of mobile sand dunes was researched by using the subsection and delaminating method together with dot clustering plot selecting and three-dots smoothing of volumetric moisture content,and by using linear and binomial models.The results showed that the calibration was satisfied,that is,the accuracy was greatly advanced and the error was reduced.It was proved that the neutron probe is a feasible and reliable way in measuring soil moisture of mobile sand dunes. |
