提出了一种估算高等植物叶绿素含量的遥感技术。叶绿素荧光在735 nm处与700 ~ 710 nm处的比值F-735/F-700与叶绿素含量成线性关系（决定系数r(2)大于0.95），可以作为植物叶片叶绿素含量的精确指标。这一新的叶绿素荧光比值表明叶绿素水平具有很高的精度，在叶绿素含量范围（41 ~ 675 rag m(-2)）小于40 mg m（-2）的范围内进行叶绿素预测。该技术在山毛榉（Fagus sylvatica L.）、榆树（Ulmus minor Miller）和野生藤（Parthenocissus tricuspidata L.） 3种植物上进行了测试和验证。(C)Elsevier Science Inc., 1999。
A remote sensing technique is presented to estimate the chlorophyll content in higher plants. The ratio between chlorophyll fluorescence at 735 nm and in the range 700-710 nm, F-735/F-700 was found to be linearly proportional to the chlorophyll content (with determination coefficient, r(2), more than 0.95), and, thus, this ratio can be used as a precise indicator of chlorophyll content in plant leaves. This new chlorophyll fluorescence ratio indicates chlorophyll levels with high precision- the eri-or in chlorophyll prediction over a wide range of chlorophyll content (from 41 to 675 rag m(-2)) was less than 40 mg m(-2) The technique was tested and validated in three plant species: beech (Fagus sylvatica L.), elm (Ulmus minor Miller), and wild vine (Parthenocissus tricuspidata L.).
