A comparative inves0igation on meteorological and hydrological factors of the evergreen and deciduous broad-leaved mixed forest as well as grass glade in Laoshan Mountian, Tianlin, was carried out from 1982 to 1990. The data were analysed with regression method. The results show that the evergreen and deciduous broad-leaved mixed forest has highly remarkable climate-ecological effects in decreasing the amplitudes of air temperature and soil temperature, increasing the relative humidity as well as reducing the physical evaporation, etc. It aiso has obvious hydroecologic effects in interception of rainfall, redistribution of precipitation, reduction of surface runoff, and prevention of soil erosion as well as conservation of water supply, and so on, indicating that the evergreen and deciduous broad-leaved mixed forest is advantageous to keep the ecological bliance in this region.
