摘要
植被净初级生产力(NPP)是植被在自然条件下的生产能力,是表征生态系统质量与功能、研究生态系统碳循环的重要指标.在总结NPP估算方法的基础上,分析了实测法、气象模型、光能利用模型、过程模型的特点;探讨了自然及人为因素对NPP的影响,以期为今后的研究工作起到一定借鉴作用.
The net primary productivity(NPP)of vegetation is the productive capacity of vegetation under natural conditions.The NPP is an important indicator for characterizing the quality and function of ecosystems and studying the carbon cycle of ecosystems.On the basis of summarizing the NPP estimation method,the characteristics of the actual measurement method,meteorological model,light energy utilization model and process model are analyzed.Moreover,the influence of natural and human factors on NPP is discussed.The purpose is to provide reference for future research work.
