摘要： 红壤丘陵区森林植被恢复后，对水分和热量均有明显的调节作用，尽管林内穿透雨只占林外降水量的90％左右，但相对湿度始终高于林外，森林可以增湿、调湿，提高水分利用效率。同时，林内气温、地温始终低于林外，随着林龄的增长，这种作用愈加明显。

关键词: 红壤丘陵, 森林植被恢复, 水分, 热量

Abstract:  This study was conducted at Qianyanzhou Experimental Station of the Chinese Academy of Scienceswhich is located in typical red earth hilly area of southern China．Since the 1980sland use in the area has been transformed from mainly wasteland and farmland into woodland and orchard land．The forest cover rate was increased from 2．06％ in 1983 to 78．21％ in 1998．With forest rehabilitationthe microclimate has obviously changed．The observation data showed that the through fall and stem flow account for about 90％ of the precipitationthe moisture inside of the forest is always higher than that outsidethe temperature and soil temperature in inside of the forest are always lower than that outside．It is evident that forest plays an important role in adjusting the moisture and temperature．

Key words: red earth hilly area, forest rehabilitation, moisture, temperature
