黑龙江省植被长势遥感监测解析

利用黑龙江省1998-2006年气象卫星NOAA-AVHRR资料,采用归一化植被指数（NDVI）,并结合黑龙江省的气象资料和土地利用资料,对黑龙江省多年的植被长势状况进行分析,并着重对比分析了2006年和2007年的植被长势。结果表明：黑龙江省多年来植被覆盖度分布规律较为明显,不同植被类型的NDVI季节变化趋势大致相同,但仍存在一定的差别,比较而言,针叶林变化幅度较小,草地、耕地变化稍大,各种植被类型的生长规律与黑龙江省的气候特点、季节分布相符。2007年黑龙江省植被长势在春季、夏季优于2006年,秋季比2006年略差。就多年总体长势而言,2007年植被长势稍差。

Remote Sensing Monitoring Resolution upon the Vegetation Growth in Heilongjiang Province

The vegetation growth in Heilongjiang province was analyzed, especially in 2006 and 2007 by using Normalized Difference Vegetation Index (NDVI) , based on NOAA - AVHRR data during 1998 -2006 combining with Heilongjiang meteorological data and land use data. The results showed that the distribution of vegetation coverage was more obvious in Heilongjiang province, NDVI seasonal trends of different vegetation types were more ot less the same, but there were still some differences. In comparison, the coniferous forest changed little, while Grassland and arable land changed more. The growth of various vegetation types was corresponding with climatic characteristics and seasonal distribution. The vegetation growth in spring and summer of 2007 was better than 2006, but in autumn was not. In totally, the vegetation growth in 2007 was worse than previous years.
