NDVI in carbon-flux plots

The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed weekly. NDVI is measured with a handheld SpectroSense 2+ system. For further details, please refer to the newest BioBasis manual available at the website.本研究每周对植被绿度的时序变化进行追踪监测，该指标采用归一化差分植被指数（Normalized Difference Vegetation Index，NDVI）表征。该归一化差分植被指数通过手持式SpectroSense 2+系统测定。如需获取更多详细信息，请查阅该网站上的最新版BioBasis手册。
