The Structural Equation Model And Application Of Groundwater Pollution Problem

Water resource is the important condition of economic and social development and people’s life improved. Our country present situation of water resources development concern, however, per capita is low, some characteristics of spatial distribution inequality, coupled with serious problems such as water pollution and destruction phenomenon, makes the governance of water pollution and protect the ecological environment has become an important task of our current. Especially the groundwater pollution has seriously affected People’s Daily life, and hinder the development of productivity, thus inhibiting the development of economy, this a series of problems that people have to put the groundwater pollution prevention and control of schedule, so the groundwater pollution prevention and governance has become an important problem people attention.In order to more specific research on groundwater pollution condition, this paper choose the pollution is more serious of Liaohe basin, by studying the influence factors to determine the index of the Liao river water pollution, so as to find out the cause of pollution. In this study analysis the process of Liaohe water quality, first of all, the water pollution index factor analysis, factor analysis model is established, and the model is used to replace the original water quality pollution indicators, more fully reflect the Liaohe water pollution situation, and then explore the main factors influencing the Liaohe water quality. From the results of this study analysis, factor analysis method combines the influence of many indexes of water quality pollution, water quality evaluation results more objective and reasonable. Factor is established on the basis of factor analysis to extract the pollution factor structural equation model of the impact of water quality, water pollution and identification, repair and test of the model, the accuracy of the model is verified, fully embodies the different degree of pollutant effect on water quality, is advantageous to the management of water environment in a timely manner for prevention and control of water pollution and purify.
