Estimation of Surface Water Quality in China

Xiu-li LIU

Abstract


It’s necessary to estimate national surface water quality to provide theoretical support for water resource planning and its safety. In this paper, models to estimate the national surface water quality were established with OLS and GM(1,1) methods. The results showed that the surface water quality in China would be improved, the proportion of I~III may reach 69.2% and the proportion of ITV will drop to 13.9% in 2015.
