基于遥感反演的山东省森林资源调节温度服务的研究

Forest Regulating Temperature Study Based on Remote Sensing Technology

森林生态服务的量化研究是森林生态服务评估的关键之一。利用TM数据、实际采集的外业数据、山东气象数据,对山东省不同树种、不同时间森林调节气温的生态服务进行了量化分析。主要结论有:温度和森林的NDVI(归一化植被指数)是负相关的关系,NDVI值越高,温度越低;森林温度变化的振幅比农田、城镇都小,森林对温度的调节作用比农田大;不同类型的降温效果不同,在不同的季节降温作用也不一样。在分析时,限定了分析的条件,森林对气温的实际调节作用远大于分析的结果。

The quantitative research of forest ecological service is one of keys of evaluation of forest ecological service. The paper studies on the forest regulation temperature ecological service for different tree species and in different time by using TM data, field surveying data and the meteorological data in Shandong Province. The conclusions of this paper are followed： LST and NDVI are the negative correlation; that the better forest cover, the lower of LST; the temperature change amplitude of forest is less than that in farmlands and cities, forest functions more temperature control than farms; the temperature decrease function is different from various species and different time. Because the analysis condition was limited, actual function of the forest t regulation temperature was larger than the e result of the paper.
