In order to study affecting the variation rule of the water quality parameters, we employed Hilbert-Huang Transform (HHT) to analyze the concentration value of Cd using 26 years' data in F3 site, and got the variation rule and trends of Cd. The results showed that: In Station F3, Cd concentration is non-stationary time series, and the trend is clearly for the upward trend, a slight decline in the...
This paper first analyzed the characteristics of relevant image classification methods based on the high spectral characteristics of the acquired airborne high spectral data, and then obtained the better airborne oil pollution classification image results of hyperspectral data through the research and using of spectral angle analysis method of image classification, which verified the feasibility of...
Marine environmental management needs automatic analysis of Marine environment monitoring data. According to the characteristics of Marine monitoring data, this paper introduces how to establish Marine environment monitoring data automatic analysis system by using computer and GIS technologies, the design and implementation of the system is also discussed. Automatic analysis of Marine environment...
