九龙江口湿地景观格局变化遥感监测与分析
An analysis on change of wetland landscape in Jiulong river estuary based on multi-temporal remote sensing images under background of urbanization
摘要
Abstract
This paper took Jiulong river estuary as an example, using multi - temporal and multi -source remote sensing data from Landsat TM and ALOS and other auxiliary data. In this study, a decision tree based classification method is used to extract wetland landscape pattern and change information from multisource and multitemporal remote sensing images during three times. The pattern of wetland landscape and its driving force in the Jiulong river estuary from the urbanization was analyzed. The result shows that wetland area in Jiulong river estuary declined significantly in the past twenty years. The total area of wetland decreased from 34 784. 78 hm2 in 1988 down to 20 775. 69 hm2 in 2009, the changement resulted mainly from rice fields, which have been gradually replaced by farms and building - up under rapid urbanization, making the Jiulong river estuary landscape fragmentation and patch density increases.关键词
