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
文摘:本文對兩期遙感圖像進行解譯，並在gis支持下提取露水河林業局主要河流兩岸各緩沖區森林資源信息，經分析得到各類地物在1985年及1999年的變化趨勢.結果表明:在河流沿岸對森林的採伐強度1999年較1985年明顯減小，整體生態環境較1985年有所改善.在緩沖區1 ， 2 ， 3除中齡針葉林大幅度增加外，其它地物類型面積均減少，由此可以看出，在這三個緩沖區內針葉林得到了較好的恢復.在緩沖區4內，中齡針葉林、成熟針葉林、成熟闊葉林形成一個林齡梯隊，有利於森林生態系統的穩定與功能的發揮，十五年間緩沖區4受到的干擾相對較小.濕地數量在四個緩沖區內均有所減少，雖然在緩沖區4內森林生態系統恢復的較好，但濕地面積仍有所減少，說明保護及恢復濕地資源是一件非常艱巨的任務，必須引起高度重視.圖5表2參12 -
