摘　　要：测定铀矿区与非铀矿区同种植物的光谱,分析含铀植物光谱特性,旨在利用光谱技术寻找更多的铀积累优势植物,进而为用植物修复技术修复铀矿采空矿提供基础。利用SVC HR-768便携式地物光谱仪对铀矿区与非铀矿区的黄荆、地锦2种植物的反射光谱进行测定,植物光谱形态结果表明,铀矿区的黄荆、地锦2种植物的反射率均比非铀矿区高,研究结果还表明,地锦含铀量与绿峰、红光谷、近红外峰及DVI等光谱参数相关。铀元素使植物光谱曲线红边蓝移、近红外抬升,植物不同,位移、抬升程度不同。In this study, the spectral of two kinds of plant, such as multicolored ladybeetle and creeper, were measured with SVC HR-768 portable spectroradiometer. This paper compared their spectrum between in the uranium ore district and the non-uranium ore district, analyzed their spectral feature. The spectral curve shape showed that reflectivity of multicolored ladybeetle and creeper in uranium ore district, were higher than those in the non-uranium ore district. The results revealed that uranium content of creeper was positive related to peak value of green band, valley value of red band, peak value of near-infrared band, and difference vegetation index. For the spectral curve of the plant containing uranium in uranium ore district, red edge blue-shift, nearinfrared band up-shift, compard to that in non-uranium ore district.
