Research On The Comprehensive Evaluation Of The Topical Groundwater Sources’ Environment In Shandong Province

Water resources is the material base for existence and development of human, as one important part of it, the eco-environment of groundwater directly affect the people’s life property safety. Aiming at the actuality that the continuous deterioration of eco-environment of groundwater, this paper chooses 8 groundwater sources from Liaocheng, Zibo, Zaozhuang, Laiwu, Weifang, Taian Jinan and Jining(Zaozhuang 2 sources, others 1) to make a comprehensive evaluation of the eco-environment of groundwater in Shandong province.The research contents are as follows:(1) Summarizing the characteristics of a good groundwater eco-environment and analyzing the influencing factors of groundwater functions, then building a evaluation system including water volume, water quality and geological hazard which can reflect the groundwater eco-environment status of Shandong province.(2) With reference to the average water level (buried depth) of the underground water source, the water quantity evaluation method of groundwater environment based on the underground water level and the depth of groundwater were determined respectively;(3) Combined with matlab and spss, this paper uses time series analysis method making analyzation and prediction of water quality indexes in different water sources.(4) It also put forward the variable weight method considering water volume, water quality and geological hazard to overall appraise the groundwater eco-environment, methods of scoring second indexes and weight determination are described, too.(5) Making a comprehensive evaluation of Shandong province groundwater environment by using the evaluation system and evaluation methods for the first time.(6) At last, according to the results, putting forward some suggestions to improve the eco-environment of groundwater in Shandong province.
