| 8. | The east transect was classified thirty five vegetation types using ndvi data from 1995 - 1996 by gis technique . the paper concludes that the ndvi from meteorological satellite is sensitive indicator of vegetation growing condition , times series curves of ndvi can truly curve vegetation growing principle by drawing the seasonal change curve of ndvi data by three groups . the paper also concludes that the forest ' s ndvi curve is commonly single apex , while farmland ' s or shrub ' s curve is mostly double apex , the peak value of forest ' s ndvi is commonly higher than grassland , farmland and some other vegetation types
应用地理信息系统技术处理1995 - 1996年1kmndvi数据，将南方样带划分为35类，分三组绘制35类植被的ndvi季节变化曲线，得出气象卫星ndvi是反映植被生长状况的敏感指示器， ndvi时间序列曲线真实地刻画出植被的生长规律；经分析得知森林ndvi曲线一般为单峰曲线，而农田灌丛多为双峰曲线；森林ndvi峰值一般高于草原、农田等其它类型。 |
