利用從同一經度的不同森林類型ndvi值分析,沿緯度方向ndvi變化可得出, ndvi在冬春季變化最明顯(尤其是在4月份最大) ,而在夏季和秋季變化不明顯。利用ndvi均值進行分析,從暖溫帶到亞熱帶到熱帶的變化情況發現,從暖溫帶到亞熱帶ndvi指數形成明顯的階躍,而其它區域沒有太大的變化,同時對幾種典型的針葉林曲線分析可知其年初的凹值源自於我國東部季風的影響。利用ndvi數據分析其與月均溫度與降水的相關性得出與溫度相關性較為顯著,而與降水相關性不顯著或無相關性。The vegetation type was classified in the east transect by unsupervised classification using the data ( ikmx 1km ) from noaa meteorology satellite from 1995 - 1996, and the article analyzed the change of ndvi of all kinds of vegetation types, in the same time analyzed the forest dynamics in typical ecotone ( warm temperate zone to semitropical in qinling woods ) using the higher spatial resolution tm data

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2參12Chinese forest law was divided into chapters and sections according to different types of forest protection activity, but japanese forest law was constructed from aspect of forest plan and forest classification
