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 well correlation times persist for about six months and the incidence level is reach or pass 0. 01. the meridional wind field which persistly impacting on sst in kuroshio region is near the west tropical pacafic. the result also behave as distinctly positive correlativity. afterwards we investigate the relationship between sst in kuroshio region and ninoc, 4 region and integrate the front conclusion. as a resultjt display that the sst in kuroshio region persists for positive relevance during the course of el - nino and inversely during the course of la - nina. subsequentl y the synthetic fields of kuroshio region ' s ssta in el - nino and la - nina years have proved the front outcome
