Assessing the Areal Variation of Mangrove Coverage Forests in the Jiulongjiang Estuary of Fujian China with Remote Sensing Data
摘要
Abstract
By using the data of LANDSAT MSS/TM/ETM satellite and the Chinese environment and disaster monitoring satellite HJ-1 A/B,the areal variation of mangrove coverage in the Jiulongjiang Estuary of Fujian province was investigated. Five multi-bands images were collected in 1976,1983,2002,2006 and 2010,respectively. The approach of maximum likelihood classification was used to detect mangrove from the images. It was found that the area of mangrove was likely decreasing during the period of 1970s-1980s (~60% drop). Recovery initiated during 1980s-2000s,and significant spread of mangrove occurred in the 2000s. The area of mangrove coverage in 2010 in the study region was about two times of the value in 1983. Such a highly variable temporal pattern was clearly different from that expected under natural forcing (~ + 4% annual change), suggest ing that it was predominantly induced by human activities.关键词
