九龙江口1999—2013年悬浮物含量和冲淤环境变化规律分析
Analysis of Suspended Sedment and Silting of Tidal-flat Change in Jiulong River Estuary From Year 1999 to 2013
摘要
Abstract
With the rapid development of economics and growing population,river water quality has changed signifi-cantly 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 se-lected.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 2013 the overall increases in the concentration of suspended solids,but upper and mid-dle concentrations of accounting from 2006 to 2013 declined suspended matter.The beach area is in constant decline.关键词
