高光谱数据在“十一五”期间生态环境状况监测中的应用

高光谱遥感以"图谱合一"等特点在生物多样性监测、土壤退化、植被重金属污染监测、生物量估算等方面都有广泛应用。通过长时间序列高光谱反演数据NDVI和NPP,较好的反映了"十一五"期间新疆生态环境V字型的变化趋势,基本符合5年新疆生态环境变化状况。高光谱数据反演技术是开展生态环境宏观监测的有效手段之一。

Application of Hyperspectral Data in the Ecological Environmental Monitoring in the ＂Eleventh Five- Year＂ Period

The map specmun - one characteristics of hyperspectral remote sensing, that was widely applied in the monitoring of biodiversity, soil degradation, vegetation of heavy metal pollution monitoring, biomass estimates. Hyperspectral inversion of long time series of data NDVI and NPP better reflected the V - shaped trend of ecological environment in Xinjiang during the ＂Eleventh Five - Year＂, in line with the five changes in the ecological environment situation in Xinjiang. Hyperspectral data inversion technique is one of the effective means to carry out the macro- monitoring of the ecological environment.
