%X 采用1 km的叶面积指数(leaf area index, LAI)产品数据，研究淮河流域2000~2016年的植被时空变化。结果表明：1) 淮河流域年均LAI为1.16，空间分布整体呈现南高北低的趋势。2) 2000~2016年淮河流域LAI整体呈现极显著增长趋势(P值为0.003)，但流域内江苏省LAI年变化趋势并不显著。3) 各省的春季LAI都呈现极显著增加趋势，各省的冬季LAI变化趋势都不显著，而各省夏季和秋季的LAI变化趋势存在差异。<br />
The aim of this study was to adopt the leaf area index (LAI) product with one kilometer to assess vegetation spatial-temporal variations in Huaihe River basin from 2000 to 2016. The results showed that: 1) The annual mean LAI in Huaihe River basin was 1.16, and the distribution of LAI was characterized by high south and low north. 2) The average annual LAI showed a significant increase in Huaihe River basin from 2000 to 2016 (P value = 0.003), and the annual trends of LAI in Jiangsu Province of the basin was not significant. 3) Summer LAI in each province showed a very significant increase trend in all provinces. The trend of winter LAI in each province was not signif-icant showed a very significant increase trend in all provinces, while LAI in each province had dif-ferent trends in the summer and autumn.
