In order to improve the management level of national afforestation,the advantages and limitations of applying remote sensing technology to national afforestation monitoring were discussed in this paper by analyzing the application and development of remote sensing technology and remote sensing data management platform,as well as summarizing the current national afforestation monitoring present condition and monitoring content,the idea of establishing the "national afforestation monitoring and evaluation system" was put forward based on remote sensing technology and the "national forest resources intelligent management platform",so did the specific solutions to its relevant constraints.
