| Abstract: | Based on the weather observation data from Xiaolongshan Forest Ecosystem Research Station from 2008 to 2010,The forest microclimate characteristics based on watershed scale were examined.The results showed that the annual temperature difference in the region of Xiaolongshan forests was 51.5℃,and the temperature changed clearly with seasons;The precipitation concentrated in July to September,which accounted for 63.2% of the total annual rain fall;Relative humidity changed with precipitation obviously;The annual average wind speed changed between 0.7 to 1.3 m·s-1,and prevailing wind were north and SSW;Exhibiting typical continental monsoon climate. |
