Macroscopical distribution pattern of land cover is a foundation for the land cover's interannual change that is being occurred by the outside driving force. In this study

unsupervised classification method have been used based on the different NDVI images which have different spatial resolution and same temporal

and the macroscopical distribution pattern of East Asian land cover was summed up. Furthermore

annual 5~9 months anomaly percentage grading images have been made using Anomaly Percentage Analysis methods based on the NOAA/AVHRR Pathfinder database

which are 8km spatial resolutions and 10 days temporal resolutions

and generalized the characteristic of interannual changes of east Asian land cover. Which are can be seen as follows: (1)Land cover dynamic of summer(5~9 month) in east Asia apparently differentiated three regions such as the northwest inland area

eastern monsoon area and northern part of east Asia. (2)Inside the monsoon area

land cover dynamics have shown to have trends of differentiate of southeast to northwest. As regards the whole

the interannual changes of land cover of Northeast China Plain

North China Plain

southwest China and Huaihe basin are relatively heavy. (3)In the edge of monsoon area

there exist an obvious dynamic zone which is expanded from northeast to southwest. This is consistent with ecological environment fragile area of northern part of China. (4)In the northern part of east Asia

the land cover's interannual dynamic have feature of zonal distribution. In the same zone

there exist difference of east to west

but the interannual changes are very simple. (5)From the interannual changes of land cover

we have seen that the land cover have trends of increase except northwest inland arid area

especially in the northern part of east Asia and midwest Qinghai-Tibet.
