利用2000-2006年MODIS的LST和NDVI的时间序列对山东省森林调节温度的作用进行了分析,主要结论有:森林温度变化的振幅比农田、城镇都小;植被的NDVI的最低值都出现在2月,温度的最低值出现在1月(针叶林类样点除外);白天,针叶林类样点的LST在2月有明显的低谷,阔叶林类样点不明显;夜间最高温度出现的时间,较白天有滞后性;LST与NDVI是呈负相关关系,即森林植被覆盖越好,温度越低。
The time series of LST and NDVI of MODIS from 2000 to 2006 were used to analyze the effect of forest regulation temperature in Shandong Province. The main conclusions are as follows: the amplitude of forest temperature change is smaller than that of farmland and town; and the lowest value of vegetation NDVI appears In February, the lowest temperature appeared in January (except for coniferous forest samples); in the daytime, the LST of coniferous forest samples had obvious troughs in February and the deciduous forest samples were not obvious; The time of temperature appeared lagging behind that of daytime. The relationship between LST and NDVI was negative, that is, the better the vegetation cover, the lower the temperature.
