Development And Protection Of Groundwater Management Problem Research In Tianjin

Tianjin city is the economic center of northern China and the international port city, an important industrial city in China, is a water scarce area. In order to meet the needs of production and living water, over the years the mining of groundwater resources is not sustainable, the waterecological environment has been severely damaged. Due to historical reasons and the level of technical limitations, groundwater resources, unreasonable exploitation of Tianjin has not been effectively controlled, the groundwater balance destroyed to some extent, causing water pollution, water level,ground subsidence, seawater intrusion, a large number of abandoned wells and the pumping depth increased the negative effect of investment, the problem of ground subsidence particularly serious.This paper discusses the status quo and development and utilization of water resources in the city of Tianjin, Tianjin city, underground water level change trend were analyzed, and put forward in the establishment of a sound management system of supply and demand of water resources allocation problems, realize the sustainable utilization of groundwater resources. The main research contents and results are as follows:(1) analysis of Tianjin city water resources development and utilization status and the amount of. Through the statistic analysis of groundwater resources in Tianjin city can use quantity and theurgency, and the shortage of water resources protection more intuitive understanding of the groundwater resources in the city of Tianjin.(2) to analyze the change trend of groundwater level, analyze and summarize the influence on Tianjin, shallow groundwater and deep groundwater level changes of groundwater exploitation.(3) proposed to protect groundwater resources management measures, put forward constructive solutions for sustainable exploitation of groundwater in Tianjin.(4) on the situation of supply and demand of water resources in Tianjin city were analyzed, improving the groundwater water resources management system.
