| 摘 要： | 通过遥感技术研究植物物候现象的机理分析,认为植被指数可反映植被各物候期的特征。国内外在探测植物生长季始末日期、花期变化、净第一性生产力变化、全球碳收支等方面的研究促进了植物物候的发展;同样物候研究也可提高遥感影像植物分类和作物估产的精度,同时可促进高光谱遥感的发展。通过我国物候研究从传统的农林业应用转向注重遥感探测、生态学应用的现状分析,展望了我国物候发展方向：关注植物生长季始末时间的时空分布规律;遥感监测植物季相变化;遥感监测植物花期;注重探讨植物生理和生态特征;植物高光谱遥感物候研究;重视物候科普普及工作。

| Abstract: | From the analysis of the mechanism of foliage phenology using remote sensing technology, we can see that vegetation index (VI) can indicate features of each phenophase. Many researches on the starting and ending days of the growing day, changes of florescence, changes of GPP, the sink and source of global carbon using vegetation index have been done. And all the above studies inside and outside speed up enlarge the fields of foliage phenology. On the other hand, the analysis on foliage phenology can improve the accuracy of vegetation classification and crop estimation. At the same time the advances of foliage phenology can speed up the development of hyperspectral remote sensing technology, too. The applied fields of phenology have been from the traditional fields of agriculture and forestry to the fields of phenological observations using remote sensing and ecological applications in the last 20 years in China. And studies on the spatial and temporal raw of the starting and ending days of the growing days, seasonal changes of plants using remote sensing, changes of florescence using remote sensing, physiological and ecological characteristics of foliage, phenophase observations using hyperspectral remote sensing technology, educating children and the general public on phenology and global change issues should be done in the future in China. And the future of phenology is very splendid in China. |
