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。
高光譜遙感以＂圖譜閤一＂等特點在生物多樣性鑑測、土壤退化、植被重金屬汙染鑑測、生物量估算等方麵都有廣汎應用。通過長時間序列高光譜反縯數據NDVI和NPP,較好的反映瞭＂十一五＂期間新疆生態環境V字型的變化趨勢,基本符閤5年新疆生態環境變化狀況。高光譜數據反縯技術是開展生態環境宏觀鑑測的有效手段之一。
고광보요감이＂도보합일＂등특점재생물다양성감측、토양퇴화、식피중금속오염감측、생물량고산등방면도유엄범응용。통과장시간서렬고광보반연수거NDVI화NPP,교호적반영료＂십일오＂기간신강생태배경V자형적변화추세,기본부합5년신강생태배경변화상황。고광보수거반연기술시개전생태배경굉관감측적유효수단지일。
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.
