摘要: |
归一化差值植被指数(normalized difference vegetation index,NDVI)是农作物监测中应用最为广泛 的光谱参数之一,在农作物生产与管理中具有重要的实际指导意义。该文就NDVI在作物产量、生物量、 收获指数、叶面积指数、营养状况、作物冻害等方面的研究与应用作一综述,并总结当前研究中存在的问 题与不足,提出了NDVI在今后作物监测中进一步的研究重点。 |

Abstract: |
Normalized difference vegetation index(NDVI) is one of the most widely used spectrum parameters in crop monitoring, which has important practical guiding significance in crop production and management. In this pa- per, the application of NDVI in crop yield, biomass, harvest index and leaf area index, nutritional status, crop ad- justment was discussed, the existing problems and deficiencies in current research were also summarized, and the research focus of NDVI in crop monitoring in future were put forward. |
Key words: crops the normalized difference vegetation index monitoring |
