Study on remote sensing quantitative model of suspended sediments in the coastal waters of Caofeidian

AO Yong,WANG Xiao-feng,KONG Jin-ling(School of Earth Sciences and Resources Management,Chang'an University,Xi'an 710054,China)  
On the basis of analysis of the field survey data reflected spectrum characteristics on Caofeidian coastal waters,we have done the correlation analysis with the synchronous pick suspended sediment concentration(SSC)and the remote sensing parameters of suspended sediments have been marked by selecting TM available channels in this paper,and the relevant inversion model of quantitative remote sensing data monitoring for suspended sediments has been established with ocean color data measured from four sections of twenty nine stations on Caofeidian coastal waters in 2008,And carried out precision evaluation with the 18 independent samples.The results show that: the reflected spectrum characteristics of Caofeidian coastal waters showed basically single-peak phenomenon,sensitive band located within the 450-700nm,maximum peak located in the vicinity of 550nm,and it's the existence of the weak peaks within the 600-700nm,but the biggest peak is not obvious;different regions,remote sensing sensitive to the choice of band is different and also the inversion are not common;the results of the error show that the quadratic polynomial of TM3 and SSC's and TM3/1 and SSC's、the linear equation of the first three components of principal component are comparatively an ideal,and the remote sensing quantitative model has gained a good effect and high accuracy,and can fulfill the quantitative survey of the distribution and variation of suspended sediments in the coastal waters of Caofeidian.Finally,the results will be considered as a basis for further research in this region.
