Abstract
本研究以幅射光譜及熱紅外線光譜影像說明光譜遙測技術評估農作物生長狀態的應用及限制，及其在監測莧菜淹水狀態上的利用。並結語只要作物植被的色澤、組織結構、組成分及生理代謝的表現影響其反射光譜特性時，無論係自身的生育進展或環境造成，均將反應在作物植被反射光譜的質與量變化，皆可利用幅射光譜遙測予以偵（檢）測。惟在限制因子的排除與拿捏，結果的解釋與應用上，仍仰賴研究人員的專業素養和具體實踐。
This paper describes the applications and limitations of using spectral remote sensing to monitoring crop growth status in the field, and the utilization of reflectance spectrum and thermal infrared image to evaluate water-logging status of Amaranihus mangostanus. In conclusions, it is found that when crop is affected by the changes of physiological metabolism and morphological modification due to growth development or environmental impacts, it may cause variation in canopy reflectance spectrum qualitatively and quantitatively. Such phenomenon can be detected by the techniques of spectral remote sensing. The ability to avoid the limitation factors and provide the suitable interpretation is based on the expertise of researchers.
