Abstract:

Data of the Shandong Provinces forest resources,including MODIS temperature,vegetation index,the field surveying data and the meteorological data in Shandong,combining with GIS,were used to study the ecological temperature regulation of forests with different tree species and in different seasons during 2000-2006 by using. The results were as the following:1) In summer forests had a function to decrease temperature,while in winter they preserved heat;2) The forests did not modulate temperature overnight;3) The temperature change in forests was less than that in farmlands and cities;4) The forests had greater capacity to modulate temperature variation over seasons than farmland did;5) In Summer,land surface temperature,(LST) and normalized difference vegetation index (NDVI) of the daytime had a negative correlation with each other,however in winter they had a positive correlation. In evening,LST was not correlated with NDVI;6) the change of LST was negatively correlated with the change of NDVI.
