Abstract:

Air and shallow soil temperature in forest site are important factors impacting carbon cycle and plant physiology of the ecosystem.It is an effective method to estimating these temperatures by the recordings at neighboring meteorological station.The estimations will fill the gap of micrometeorological measurements in forest area.An empirical model to estimate the air temperature in the crown and soil temperature at 5 and 20 cm depth in the mixed forest of broad_leaved and Korean_pine was established,according to the recordings at adjacent meteorological station.The effects of seasons and snow coverage were taken into account in model establishment.The results showed that estimations were well accordance with the measurements.

Key words: air and shallow soil temperature, the mixed forest of broad-leaved and Korean-pine, meteorological station
