【摘要】 本文重点阐述在全国植被生态环境动态监测中NOAA气象卫星(FY-1气象卫星)AVHRR的资料处理方法(叠加法),用该方法制作的拼图消除了云的影响。同时分析了用全国植被图对全国植被生态环境进行动态监测所得到的初步结果。分析表明,这种拼图不但能用于植被生态环境的动态监测,而且可用于气候变化的监测,不同年、季、月的拼图十分明显地反映出全国植被的年、季、月的动态变化以及同一时期的地域界线与气候界线,说明植被的地域分布的差异与气候有关。本项研究制作的拼图已业务化,为深入研究洲际及全球变化打下了基础。更多还原

【Abstract】 The focus of this paper is put on the method(iterate method) of processing AVHRR data of NOAA(FY-1) meteorological satellite in monitoring vegetative ecological environment over the whole China.The mosaic image made with this method eliminates cloud influence.The primary results of monitoring the ecological environmrnt by utilizing the vegetation maps over the whole China is also presented which shows that the mosaic image cannot only.be used in monitoring vegetative ecological environmrnt,but can also be used in monitoring climatic changes.Mosaic images made in different years,seasons and months exhibit apparantly the yearly,seasonal and mothly changes of vegetation over the whole country and it also shows apparent reginal division and climatic lines which indicate the exsiting relationship between difference of reginal distribution of vegetation and climate.The processing of mosaic image refered in the study has been operationalized,it becomes the foundation of further studys on continental and globle size,更多还原
