| 摘 要： | 采用ISI921VF-256型地物光谱仪对低山丘陵草甸草原植物群落和裸地的反射率光谱特征进行了测定和分析。结果表明:(1)草甸草原植物群落的光谱反射曲线在可见光波段具有明显的峰谷特性,在近红外波段呈强反射。(2)草甸草原植物群落的光谱反射率随退化程度的加深而增强。(3)在同一退化梯度下,草甸草原裸地的反射率在可见光波段大于植物群落,而在近红外波段小于植物群落;大针茅群落对可见光的反射率小于冷蒿群落,而对近红外光的反射率大于冷蒿群落。 |

| Abstract: | Using ground object spectrometer ISI921VF-256,hilly meadow steppe and bare ground reflectance spectral characteristics were measured and analyzed,The results showed that:(1) Different ground objects had different reflectance,the spectral reflectance curve of the meadow steppe plant communities had obvious characteristics of peak and valley in the visible spectrum band,and had strong reflection in the near-infrared band.The reflection curve of the bare lands in the visible spectrum band was higher than that ... |
