With the experimental ways of locating observation for the forest micro-climate by observation tower. Based on the annual observation data of Shennongjia Forest Ecosystem Research Station in 2017,this paper applied air temperature,air humidity,wind speed,vapor pressure,rainfall,solar radiation,soil temperature and humidity to analyze the meteorological factors in Pinus amandii plantation.The results showed:From January to March and October to December,the air temperature was higher in the forest than it out of forest,and the soil temperature gradually increased with the increase of soil depth.While from April to September,the relativity was opposite.The air humidity was high in different month,and the change was small.Compared to the wind speed in other two height out of forest,it was low in the forest,and it decreased 47.15%and 53.19%respectively.The vapor pressure was biggest in August,and it was significantly positive correlated with air temperature.The annual solar radiation was 645.6 MJ/m2 in forest,and the order of solar radiation was summer(245.1 MJ/m2)>spring(197.1 MJ/m2)>autumn(113.0MJ/m2)>winter(89.4 MJ/m2).
