  • 標準化植被差異指數(shù)
  • 歸一化差異植被指數(shù)

Examples

  • Advances in drought monitoring by using remotely sensed normalized difference vegetation index and land surface temperature products
    基于植被指數(shù)和土地表面溫度的干旱監(jiān)測模型
  • Then based on the method of dimidiate pixel model , the current model is improved , and the model of deriving vegetation fraction from normalized difference vegetation index ( ndvi )
    然后在像元二分模型的基礎上對已有模型進行改進,建立用ndvi歸一化植被指數(shù)估算植被覆蓋度的模型。
  • This technique is mainly involved two steps : 1 ) vegetation effects correction : we used ndvi ( normalized difference vegetation index ) derived from tm and avhrr measurements for spatial and temporal variations of vegetation covers at different scales
    但由于電磁波與地表相互作用的復雜性,雷達后向散射系數(shù)除受地表介電常數(shù)(土壤水分)影響外,還受到地表粗糙度、土壤類型、植被覆蓋以及雷達入射角、頻率、極化等多種因素的影響。
  • After analysis of tm / etm + data ' s advantage over the forest change detection , tasseled cap transformation , principal component analysis and normalized difference vegetation index were chosen to enhance the vegetation spectral information . expert classification system was adopted to extract the main tree species in the littoral shelter forest
    在分析etm +數(shù)據(jù)在森林資源監(jiān)測中的優(yōu)勢的基礎上,通過纓帽變換、主成分分析和植被指數(shù)法增強植被光譜信息,結合專家分類系統(tǒng)對沿海防護林主要樹種進行提取。
  • The authors have developed a device for measuring the normalized difference vegetation index ( ndvi ) by using four specially designed photoelectric detectors ; the ndvi can reflect the growing information and seasonal nitrogen fertilizer requirement of crops , and offers guidance for rational application of nitrogen fertilization
    文中提出了一種由4個專門設計的光電探測器直接得到歸一化植被指數(shù)的測量方法,該參數(shù)能夠反映作物的生長狀態(tài),知道不同季節(jié)的農作物對氮的需求量,對實施變量精準施肥具有重要的指導作用。
  • Firstly , this dissertation estimated the size of carbon source ; sink and net carbon sink of farmland ecosystems in china costal regions ( including ten provinces ) with statistic data from 1981 to 2001 , which include data of crop yield and agricultural consumptions . then analyzed the temporal - spatial differences of carbon source , sink and net carbon sink of china costal farmland ecosystems . secondly , estimated npp ( net primary productivity ) of farmland ecosystems in china costal regions with per month noaa - avhrr ndvi ( normalized difference vegetation index ) data and estimation model
    本文首先運用1981 - 2001年的統(tǒng)計資料(作物產量和各種途徑的農業(yè)投入數(shù)據(jù)) ,對沿海十省區(qū)農田生態(tài)系統(tǒng)碳源匯及凈碳匯進行了估算,并分析了其時空差異;然后運用1998年逐月ndvi數(shù)據(jù)通過建模對沿海地區(qū)農田生態(tài)系統(tǒng)npp進行了估算,并分析了npp分布與農田生態(tài)系統(tǒng)碳吸收的相關性;最后通過對農田生態(tài)系統(tǒng)碳源匯的影響因素分析,提出了不同的農田生態(tài)系統(tǒng)碳增匯減排技術。
