通过对南昌梅岭长岭林场木荷生物防火林带的温湿度观测，分析了气温和空气相对湿度的日变化规律，旨在研究不同季节防火林带对温湿度的影响，以期为推广生物防火林带的建设提供阻火理论依据。根据林带内外不同季节不同高度温湿度测定，结果表明：不同季节防火林带内较林外空旷地可降低日平均气温0．1℃～1．8℃，各季节最大降温幅度的高度层依次为春季（20 cm）、夏季（20 cm）、秋季（20 cm）、冬季（150 cm）；不同季节防火林带内较林外空旷地可提高日平均空气相对湿度1．2％～45％，其中夏季20～50 cm增湿效果最明显，增加14％～45％；100～150 cm以春、冬增湿效果明显，增加7．8％～10％；温度降低1．0℃，秋冬季可提高4％的相对湿度。生物防火林带具有降低空气温度、增加空气相对湿度提高阻火能力的作用。

Through the observation of temperature and relative humidity in the Changling Forest Farm of Schima superba biological fire prevention forest in MeiLing ,Nanchang City ,the rules of daily changes of tem-perature and relative humidity were analyzed ,aiming at studying the effect of forest fire prevention in different seasons on temperature and humidity so as to provide theoretical basis for the construction of biological fire pre -vention forest .The temperature and humidity at each height in different seasons inside and outside the forest were measured .The results showed that:clearing could decrease the daily average temperature by 0.1℃to 1.8℃,the heights of the maximum cooling rangs in each season were 20 cm in summer spring,20 cm in autumn, and 150 cm in winter;Fire protection forest in different seasons in a reunite clearing can improve daily average relative humidity by 1.2%-45%,its air humidification effect was most obvious in summer ( at 20-50 cm) in-creasing by 14%-45%;at 100-150 cm its humidification effect was obvious in spring and winter ,increasing by 7.8%-10%;with the decrease of temperature by 1.0 ℃,the relative humidity could be increased by 4%in autumn and winter .Biological fire prevention forest belt has the effect of lowering air temperature and raising air relative humidity .
