| Abstract: | According to the space alteration level of the soil water content, using the mathematic statistics method the needful repeated measuring number of the soil water content has been decided under the accuracy of 10% and 0.90 degree of confidence.
The needful repeated measuring number at Zhangye experimental site is 5 times above 80 cm; 8 times for 90 cm and 10 times for 100cm in soil and at Linze experimental site that is 12, 13, 14times for 5, 70 and 80 cm layers in soil, respectively. At the rest layers that is less than 7 times. If the accuracy is 15% and the degree of confidence is 0.90, the needful measuring number will be less than 6 times at Zhangye and less than 8 times at Linze. |
