摘　　要：利用W eatherHawk全自动气象站对浙西低山区不同林型(杉木林、侧柏林和马尾松林)和杉木林不同空间位置(林外空旷地、林缘、林窗和林内)的太阳辐射强度、大气温度和大气相对湿度进行了连续观测。结果表明:不同林分和林内空间位置太阳辐射强度、大气温度和大气相对湿度日进程呈多峰曲线;太阳辐射强度和大气温度日均值在不同林型内大小顺序为林外空旷地>杉木林>马尾松林>侧柏林,在杉木林不同空间位置的日均值大小顺序为林外空旷地>林缘>林窗>林内,大气相对湿度顺序相反;林外空旷地的3个气象因子日进程晴天呈单峰曲线,阴天表现多峰曲线;林分内3个气象因子波动幅度比林外空旷地小,侧柏林的降温保湿能力最好。By using the WeatherHawk automatic weather station, solar radiation, air temperature and air relative humidity of different forest types （ chinese fir plantation, chinese arborvitae plantation and masson＇ s pine plantation ） and different spatial position of chinese fir plantation （open field, forest edge, forest gap and inner forest） , were continuously observed in the low mountain of western Zhejiang. The main results showed： diurnal change of solar radiation, air temperature and air relative humidity showed multiple peak curve in different forest types and different spatial position of chinese fir plantation ; Opposite to air relative humidity, the daily mean value sequence of solar radiation and air temperature in different forest types was open field, chinese fir plantation, masson ＇ s pine plantation and chinese arborvitae plantation, while the daily mean value sequence in different spatial positions of chinese fir plantation was open field, forest edge, forest gap and inner forest ; Diurnal change of solar radiation, air temperature and air relative humidity of open field showed muhiple peak curve in cloudy days, while showed single peak curve in sunny days. The fluctuation range of three meteorological factors in forest was smaller than open field, mourning cypress plantation had the best ability of temperature decreasing and moisture keeping in three different forest types.
