Abstract: Light intensity,air relative humidity,air temperature,soil temperature and soil moisture in six different communities were measured at upper Minjiang River watershed along the process of community restoration.The results showed that,the light intensity,soil surface temperature,air temperature and their fluctuation declined with the development of the community. At the same stage of community reintegration,the natural communities had higher air temperature and lower humidity than those of artificial communities.With the development of community regeneration,the soil moisture of the old-field increased,with that of the upper layer (0～15 cm) and middle layer (15～30 cm) of artificially regenerated communities enhanced,and that of lower layer soil moisture (30～45 cm) reduced.The soil moisture of natural communities was higher than others.With the development of community regeneration,the community microclimate habitats became better and steadier.
