摘要： 以全国森林覆盖率最高的福建省为研究对象，利用2000~2017年夏季的MODIS EVI植被指数数据和气象与非气象因子进行协同分析，以揭示近17年福建植被的时空变化及其影响因子。结果表明：研究期内福建的EVI均值整体上升，从2000年的0.454上升至2017年的0.505，17 a间上升了11.2%，表明福建省的植被整体处于变好的状态，且在中部和西南部的变化最明显。相关分析表明，在研究期内，气象因子(气温和降水)对EVI变化的影响不显著，植被的变好主要为非气象因子的作用。EVI的提高主要得益于2003年福建省建设生态省后森林覆盖率的提高，并和2012年开始的水土流失治理有明显关系，这说明人类活动的积极作用对福建植被的变好起到了关键的作用。 关键词： MODIS;  时间序列;  EVI;  植被;  福建     Abstract: Fujian province has the highest forest coverage rate in China for decades, which has played an important role in maintaining a good ecosystem quality in southeastern China. This study conducted an investigate aiming to find out the spatial and temporal changes of the vegetation status in Fujian and the impact factor involving in the vegetation growth during the period from 2000 to 2017, using the summer data of MODIS Enhanced Vegetation Index (EVI) product, associated with meteorological and non-meteorological data. The results showed that the mean EVI of Fujian rose as a whole during the 17 study years, from 0.454 in 2000 to 0.505 in 2017, increased by 11.2% in the period. This indicates that the overall vegetation status in Fujian has been improved, especially in, south and west parts of the province, while eastern coastal areas have shown decrease in vegetation coverage. Correlation analysis showed that during the study period, meteorological factors (temperature and precipitation) had no significant impact on the provincial EVI change, and the improvement of the vegetation status mainly due to non-meteorological factors. Both the construction of the ecological province in Fujian starting in 2003 and the soil erosion treatment starting in 2012 have strong relationships with vegetation increase. The increase of forest coverage rate and the decrease of soil erosion area have contributed significantly to the enhancement of Fujian’s EVI in the past 17 years.
