Title
Concentration Estimation of Coastal Organic Substance by Complex Systems Theory
Abstract
A new approach for concentration estimation of coastal organic substance was put forward through study on complex systems theory. Firstly, the COD monitoring data of Tianjin’s coastal marine from the 20 monitoring points were prepared. Secondly, a typical multi-fractal method, which called the method of moments, was applied to compute the multi-fractal dimension spectrum function f(a) of COD. The curve of a(a)-f(a) was a continuous curve, which indicated that the spatial distribution mode of coastal organic substance was not a normal distribution or logarithm normal distribution, but a continuous multi-fractal distribution. Then, the MATLAB program of fractal surface interpolation algorithm was made to estimate the concentration of organic substance in coastal marine. Then, the COD concentration of organic substance in the whole area was gotten. The case analysis shows the method presented can identify the spatial pollution characteristics from the coastal organic substance monitoring data, which overcome the shortages of the precious method for the complexity of coastal marine water quality change.
