Abstract
锛?/p>
The vegetation NPP study is one of the important research topics about global carbon
cycle and storage. Based on reviewing the types of vegetation NPP models
锛?/p>
this paper amplified the
methods and mechanisms of climate productivity models
锛?/p>
biogeochemical models
锛?/p>
light energy use
efficiency models and ecological remote sensing models
锛?/p>
and the importance of remote sensing
estimation models was emphasized.The above results showed that the model estimation of NPP in
grassland ecosystem was one important and widely accepted research method
锛?/p>
and was the important
developing direction of grassland NPP estimation in the future.
