利用 NOAA AVHRR 遥感资料反演得到的中国地区19年(1982—2000)逐月光合有效辐射分量(FPAR)与英国气候变化研究中心(CRU)高分辨率格点资料中逐月平均的近地面气温和降水进行时滞相关分析。结果表明,我国大部分地区 FPAR 与同期气温的相关为显著正相关,说明温度对植被的即时强迫很强；而 FPAR 与超前一月的降水相关系数最大,均为正的显著相关,特别是在春季华北地区,表明前一月的降水对植被生长影响很大。 FPAR 与温度的相关性在春、秋季最明显,FPAR 与降水的相关性在春、夏季最强。

Time-lag correlation coefficients between monthly fraction photosynthetically active radiation (FPAR), derived from satellite remote sensing by NOAA Advanced Very High Resolution Radiometer(AVHRR),surface air temperature and precipitation from Climatic Research Unit(CRU)of high-resolution climatic girds data during the 1 9-year period(1 982-2000)are analyzed for the whole year and four seasons.The simultaneous correlation of FPAR with temperature has a significant positive correlation in most parts of china,particularly in the Northeast,this result shows that temperature imposes a significant instantaneous forcing on FPAR.While precipitation’s impact on FPAR is greatest at one-month lead,the correlation coefficient is a significant positive correlation in china,especially in North China region on spring time,the result shows that the precipitation at one-month lead impacts on vegetation growth in a large part.The correlation of FPAR with temperature is significant on spring and autumn time,and the correlation of FPAR with precipitation is significant on spring and summer time.
