Study on dynamic relationship of spring water in Jinan spring area based on gray relational analysis

Springs Jinan to spring sparks spectacular and famous at home and abroad. With the development of the city and the increase of the amount of groundwater, the gas inflow of Jinan spring group in the late 1960s has been declining. In the early 1970s, Baotu Spring has dried up in the dry season. Since then, the spring water in most years has been cut off and the drying time Growing. In recent years, under the leadership of the provincial and municipal governments, through the joint efforts of various departments and in the extreme conditions of precipitation, making Jinan spring has been spewing more than 4 years. In this paper, the changes of groundwater level fluctuation in the western part of Jinan and the urban area in Jinan in 2015 are analyzed. The gray relational analysis method is used to study the fluctuation of groundwater in the west of Jinan and the spring area of Jinan City. Through the calculation of the correlation degree, it is found that the mean value of the correlation between the groundwater level of the monitoring wells and the water level of the spring water in the urban area is 0.7738. This data indicates a higher degree of correlation. Thus, the amount of groundwater in Jixi and Jinan City is illustrated by the presence of hydraulic connections. But to protect the famous spring spewing, reproduce the natural landscape of water and build a harmonious water city, this ambitious goal is still good and fast development process in Jinan, a subject.
