Research of forest regulating temperature based on time-series of Shandong Province

Forest regulating temperature ecosystem services was mainly that forest had the cooling effect in summer and warming effect in winter. Land surface temperature (LST) and normalized difference vegetation index (NDVI) were important parameter of forest regulating the temperature. This paper studied forest temperature changes with time using the time-series of LST and NDVI. Five typical samples were respectively selected from urban areas, farm, coniferous forest, broadleaf forest. The conclusions were followed: farm regulating temperature was less than forest; the lowest value of NDVI of the vegetation occurred at Feb., which lagged the time of the minimum LST occurred at January; the LST of conifer sample point had obvious low ebb, and the low ebb of broad-leaved sample point was not obvious; LST and NDVI were the negative correlation in the day, this was, the better of the vegetation cover, the lower of LST.
