摘　　要：为揭示油松中龄林的气候效应,笔者运用自动气象站对晋东南油松中龄林林内外的气温、相对湿度、风速和风向、气压进行了为期1年的同步、连续观测,分析不同因子在林内外变化特征的差异性。结果表明,太行山油松中龄林林内外气温、相对湿度、风速、气压、太阳辐射的变化趋势相近,林内的年平均气温、年平均相对湿度、年平均气压、年平均风速、年平均太阳辐射强度分别为6.43℃,69.06%,0.09 m/s,87.94 KPa和39.67 W/m^2;林外分别为8.92℃,62.27%,0.82 m/s,87.81 KPa和137.14 W/m^2.油松林具有降温、防风、增湿、改变风向和减少太阳辐射的作用。此外,油松中龄林不仅具有明显的小气候效应,且改变了上述气象因子的相关性。To study the microclimate effect of the middle-aged Pinus tabulaeformis forest,temperature,relative humidity,wind speed,wind direction and air pressure inside and outside the forest of middle-aged Pinus tabulaeformis forest in Southeast Shanxi had been observed synchronously and continuously for a year used automatic weather station.And the differences of the change characteristics of different factors inside and outside the forest were analyzed.Results showed that the changes of temperature,relative humidity,wind speed and solar radiation inside and outside the forest were similar in the middle-aged Pinus tabulaeformis forest of Taihang mountain.The annual average temperature,annual average relative humidity,annual average air pressure,annual average wind speed and annual average solar radiation intensity in the forest were 6.43℃,69.06%,0.09 m/s,87.94 kPa and 39.67 W/m^2 respectively,while these outside of the forest were 8.92℃,62.27%,0.82 m/s,87.81 kPa and 137.14 W/m^2.Pinus tabulaeformis forest had the functions of cooling,windproof,humidification,changing wind direction and reducing solar radiation.The middle-age Pinus tabulaeformis forest not only had obvious microclimate effect,but also could change the correlation of the above meteorological factors.
