简介: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。本文以山东省的森林资源为研究对象,利用MODIS温度产品、植被指数产品、实际采集的外业数据、山东省气象数据等资料,结合GIS技术,对2000-2006年山东省森林不同时间的温度数据进行了量化分析,是对大范围的森林调节温度的生态服务功能进行量化的尝试,得出了森林调节温度的相关规律:(1)森林夏季具有降温作用,冬季具有保温作用;(2)森林温度变化的振幅此农田、城镇都小;(3)农田降温和保温的效果都不如森林显著;(4)在夏季,白天森林地表温度(LST)和归一化植被指数(NDVI)是负相关的关系,冬季是正相关的关系;无论冬夏,夜间森林的LST与NDVI几乎不存在相关性;(5)LST变化与NDVI变化的相关性比LST变化于降水变化的相关性强。
