Analysis of Regional Meteorological Factors for Dagangshan Forest Ecosystem Research Station

With the experimental ways of locating observation of the microclimate out of the different forest, based on the observation data of Dagangshan Forest Ecosystem Research Station from 2001 to 2002, this paper applies solar radiation, sunlight hours, air temperature, air humidity, soil temperature, rainfall, evaporation, wind speed, wind direction etc. to analyze the meteorological factors in and out of the forest of the station. The results show:(1)the characteristic of ground is the key factor, which influences on the meteorological change; the variation of temperature and humidity is little and approximates static breeze status in the forest; the temperature of barren land, the daily variation of humidity and the annual variation of humidity are higher; evaporation increases; average wind speed increases. (2)different forest types and coverage affect on the meteorological factors deeply.
