| 摘 要： | 要充分利用多光谱遥感数据,地面资料是必不可少的,其中最重要的是需要有具有代表性的地表光谱数据库。作者通过对研究区实地测量,初步建立了地表光谱数据库,并且利用猛进水库地物反射光谱季节的观测资料和TM影像资料获取的地面反射率数据构成的归一化植被指数(NDVI)等进行分析,结果显示:水体、草滩和水泥路的反射光谱各有特点,易于从波段组合来区别各种地物。

| Abstract: | In order to take full advantage of multispectrum data, ground information is absolutely necessary, and it is important to build a representative spectral library. The writers have primarily built the spectral library of surface features by field survey to Mengjin reservoir and vicinities, Xinjiang Uygur Autonomous Region, and have analyzed the observations of spectral reflective properties of surface features and the NDVI(Normalized Difference Vegetation Index) gained from TM images. The results showed that the spectral properties of water area, pasture and cement road were different, by which each surface feature can be distinguished through wave band combination. |
