植被NPP估算的模型方法与机理

摘要

植被NPP研究是全球碳循环与碳蓄积研究的重要内容之一。该文在回顾植被NPP模型类型的基础上，详述了气候生产力模型、生物地球化学模型、光能利用率模型与生态遥感模型实现的方法与机理，同时强调了遥感估测模型的重要性。上述结果说明利用模型估算植被NPP是一种重要且被广泛接受的研究方法，是未来植被NPP估算研究的重要发展方向。%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,this paper amplified the methods and mechanisms of climate productivity models,biogeochemical models,light energy use efficiency models and ecological remote sensing models,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,and was the important developing direction of grassland NPP estimation in the future.
