| 摘 要： | 利用EOS/MODIS卫星遥感数据,针对MODIS的应用特点,借鉴国内外基于遥感手段监测植被的方法以及植被指数的研究进展,探讨了草地变化动态监测的方式和方法。以乌鲁木齐地区为研究对象,用植被指数最大合成法,合成了该地区2004年4月至10月每个月的最大植被指数图。同时,利用每月合成的最大植被指数图,以乌鲁木齐南郊天山中段北坡的草地为典型研究区,通过典型区野外实地采样得到与MODIS影像资料时相一致的草地地上生物量数据,并利用ENVI软件提取出典型区各样点的植被指数值,分析了遥感植被指数与植被生物量的相关关系,从而建立起了植被指数在草甸和草原不同季节的生物量估测模型。

| Abstract: | This text make use of the new generation EOS/ MODIS satellite remote sensing data,aiming applied characteristics on MODIS,use for reference domestic and international method of monitoring vegetation based on remote sensing instrument and research progress of vegetation index,discussing the way and the method of grassland variety dynamic monitoring.Regard area of Urumqi as the research object,use the MVC of vegetation index,synthesized the maximum monthly vegetation index map from April of 2004 to October on this area.At the same time,regard grassland of the north slope of Tianshan Mountain midsection at south suburb of Urumqi as the typical studying area,through the sampling on the spot,getting the biomass data on the ground of grassland that compatible with the MODIS imaging datum.And utilize ENVI software to draw out the typical area vegetation index value at various spot,analyzed the relevant relations between the vegetation index of remote sensing and vegetation biomass,thus set up the estimate model of biomass for vegetation index in meadow and grassland in different seasons. |
