摘要
淮河流域作为全球变化的敏感区域,分析其植被生产力变化特征具有重要意义。基于EOS/MODIS卫星遥感资料,对安徽淮河流域植被净初级生产力(NPP)变化的时空特征进行了分析。结果表明:2000-2006年安徽淮河流域年平均NPP为336.62gc/m2,其中,2004年NPP最大,为380.73gc/m2,2000年最小,为298.76gc/m2;根据年NPP分布显示,淮河以南地区的植被生长状况要好于淮河以北地区,在淮河以南地区,长江以南的植被生长状况要好于长江以北地区,主要因为这些地区多为森林,植被覆盖度高。2000-2006年间,安徽淮河流域NPP总体呈增加趋势,淮河沿岸NPP增加明显。
As a sensitive area of global change, analysis of the terrestrial NPP（Net primary production） in the Huaihe River Basin has the significance effect. Based on the MOD17A3 data of NASA EOS/MODIS, the terrestrial NPP in the Huaihe River Basin in Anhui Province during the 2000 to 2006 is analyzed. The results showed that the annual NPP of the regions is 336.62gc/m2 during the seven years, with the maximum of 380.73gc/m2 in 2004, and minimum of 98.76gc/m in 2000; From the distribution of annual NPP, the situation of the vegetation growth in the south area of the Huaihe River Basin is higher than the north area. In the south area of the Huai- he River Basin, because of the influence of the forest, vegetation in the south area of the Yangtze River Basin is higher than the north area; On the whole, the NPP showing an increasing trend during the 2000 to 2006 in the Huaihe River Basin in Anhui Province, especially in the coastal area.
