| 摘 要： | 利用SVCHR-768便携式地物光谱仪对铀矿区与非铀矿区的四种植物的反射光谱进行测定,采用移动平均法进行了噪声去除,同时利用导数光谱技术清除植被环境背景影响。结果表明,铀矿区的黄荆、芒萁骨、商陆和4的反射率值均相应的比非铀矿区处的大;铀矿区的黄荆、芒萁骨和商陆均出现"蓝移"现象,且芒萁骨在铀矿区的"蓝移"值最大(11nm);铀矿区的地锦出现"红移"现象,红移了6.8nm;同时铀矿区的植物中芒萁骨的"绿峰"处反射率值为0.24、"红谷"处反射率值为0.08,峰谷间的差值在所测植物中也是最大的(0.16)。

| Abstract: | The reflection spectrum of four kinds of plants in uranium and non-uranium ore district are measured with SVC HR-768 portable spectroradiometer.The moving average method is used for noise removal,and derivative spectrum technology is used to remove the influence of environmental background.The results show that reflectivity of Negundo Chastetree,Dichotomy Forked Fern,Radix Phytolaccae and Parthenocisus tricuspidata in uranium ore district are greater than those in non-uranium ore district.Negundo Chastetree,Dichotomy Forked Fern and Radix Phytolaccae in uranium ore district show a "blue shift".The "blue shift" of Dichotomy Forked Fern is the maximum with 11 nm.Parthenocisus tricuspidata in uranium ore district show a "red shift" with 6.8 nm.The spectrum reflectance of "green peak","red valley" and difference between peak and valley of Dichotomy Forked Fern is 0.24,0.08 and 0.16,respectively. |
