  1. Abstract : the restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. through interpreting the images of remote sensing in 1985 and 1999, the basic information of forest resources of lushuihe forest bureau, which is a typical forest area of changbai mountain, was obtained with support of gis. by dividing land covers of lushuihe area into 10 types ( water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man - made young forest ) and dividing the riparian zone into four buffers ( in turn, 1000, 2000, 3000, 4000 m away from the river ), the changes of riparian forest resources during 1985 - 1999 were analyzed. the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. in buffer 1, 2, 3, the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. midlife conifer forest had a comparatively good status in the three buffers. in buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions. area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task
