基于 MODIS/NDVI时序数列的广西九万山植被覆盖动态变化
Dynamic Changes of Vegetation Cover Based on MODIS/NDVI in Jiuwan Mountain of Guangxi
摘要
Abstract
Based on the continuous MODIS data from 2000 to 2014, the variations of NDVI in Jiuwan mountain were analyzed.The results showed that the plantations were growth well, the annual mean NDVI were all above 0.54, the NDVI showed a slow increase trend which varied with years.From the time perspective, the vegetation cover show a slow upward trend, a peak value and a minimum value occurs during respectively 2008, 2009;From space point of view, the south of this area vegetation coverage is highest, North Second, the central part is the lowest, the vegetation cover mainly was in medium and high;Vegetation cover variation rate show that NDVI from 2000 to 2014 for 15 con-secutive years has decreasing but also increasing.Decadal variations was negative for six years, the rest of the year is positive, the rate of change in 2009 reached the extreme.关键词
