The meteorology data got from the ultrasonic anemometer were analyzed, and the results showed that the calculated C_n~2 was well agreement with the C_n~2 measured directly by the micro-temperature sensor.

By using the flume experimental data by Micro ADV in sediment\|laden flow, and analyzing the data from LDV and Strain\|kinemometer, the quantify relationship of the turbulence intensity with the velocity and its gradient is established.

Detrending correction and sonic anemometer tilt correction were made to modify the raw time series measured from eddy covariance system in broad-leaved Korean pine forest of Changbai Mountains during the growing season of 2003,and the impact of different correction methods on CO 2 flux was analyzed quantificationally.
