Control stratory in coastal area using Markov Chain and Random Forest

Abstract

Economy in coastal cities plays an important role in China. It is urgent to protect environment with economy developing. Four types of sea water quality can be regarded as states of Markov Chain. Transfer probability is viewed as the function of sewage and investment in environmental protection. Based on historical datum in Tianjin, the function is estimated by Random Forest. Given objective of sewage reduction and environmental investment, transfer probability matrix can be calculated and long-term proportion of four types of sea water is obtained. It provides scientific reference for design goal of sewage reduction and environmental investment in reason. Keywords -Environmental investment, sewage reduction, Markov chain, random forest ___________________________________ 978-1-61284-449-7/11/$26.00 ©2011 IEEE
