ENVIRONMENT OF MICROCLIMATE OF MONSOON EVERGREEN BROAD-LEAVES FOREST IN DINGHUSHAN

The differences of microclimate between monsoon evergreen broad leaves forest and bare land was analyzed in this paper.The results are as follows:The annual average reflectivity is 10.5% and air temperature is 19.9℃ for monsoon evergreen broad leaves forest,and they are lower than the bare land's.The annual average relative humidity is 87% and higher than bare land's.The annual average potential evapotranspiration is 987.50 mm and moisture index is 0.96.The diurnal changes of surface soil temperature are not obvious, but bare land's is.From above to below,the soil temperature cuts down by and by in spring and summer and goes up by and by in autumn and winter in both monsoon evergreen broad leaves forest and bare land.
