中国区域植被与温度和降水时滞相关分析
Observed vegetation-climate lagged correlations in China
摘要
Abstract
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.关键词
