| 摘 要： | 本实验以荒漠草原2个不同种类的土壤为研究材料,使用TRIME - IPH型TDR测定不同放牧强下的土壤含水量,并以烘干法测定值为真实值对其进行了标定.结果表明:室内标标定中的TRIME - IPH测值与烘干法测值都具有良好的相关性,沙土中的相关系数(R2=0.983 9)略低于壤土(R2=0.986 0),而平均相对偏差(16.4％)大干壤土(12.3％).校正方程为TDR校正值=0.998 0烘干法测定值+2.3900.在野外标定中,不同放牧强度下TRIME - IPH测值与烘干法测值的相关性也很好,总体校正的相关系数为0.774 3.本研究结果证实,TRIME - IPH完全能够胜任该地区土壤水分动态特征及变化趋势的研究工作. |

| Abstract: | In this experiment,two different types of desert grassland soil as research materials,TRIME-IPH model using different grazing intensities measured TDR soil moisture,and drying method is to calibrate its true value.The results showed that: Interior Standard Calibration TRIME-IPH measured value and the measured values of drying method has a good correlation,the correlation coefficient of the sand(R2 =0.983 9) lower than loam(R2=0.986 0),while the average relative deviation(16.4%) Is greater than loam(12.3%).Correction equation for the TDRcorrection = 0.987 9 method to measure the value-2.111 8 drying.Calibration in the field,under different grazing intensities measured values TRIME-IPH and drying method to measure the value of the correlation is also very good,the overall correlation coefficient of 0.774 3 correction.This study confirmed that,TRIME-IPH fully competent in the area of soil moisture characteristics and trend research. |
