摘要
近年来九龙江区域经济迅速发展,人口迅速增长,流域水质变化明显。利用Landsat卫星遥感影像为数据源,选用1999年9月,2006年9月及2013年8月的高潮时影像,根据其波段反射率与悬浮物浓度的相关性质,利用(B2+B3)/(B2/B3)提取九龙江口悬浮物浓度分布变化信息。分析结果表明:1999年至2013年悬浮物浓度总体上升,但2006年至2013年悬浮物中高浓度占比有所下降;在此期间,滩涂面积则处于持续下降状态。
With the rapid development of economics and growing population,river water quality has changed significantly over the years in Jiulong River Estuary.In this paper,Landsat satellite remote sensing image is used as the data source,in which image when the climax September 1999,in September 2006 and August 2013 image when the climax are selected.According to the nature of the spectral reflectance associated with the concentration of suspended sediment,（B2＋B3）/（B2/B3）is used to extract Jiulong River Estuary suspended sediment concentration distribution change information.The results showed that from 1999 to 2013the overall increases in the concentration of suspended solids,but upper and middle concentrations of accounting from 2006 to 2013declined suspended matter.The beach area is in constant decline.
