Zaozhuang City Yang Zhuang Groundwater Under The Support Of Gis Resources Dynamic Analysis

Yangzhuang basin in the city of Zaozhuang is one of the sources of karst groundwater in the south of Shandong province. National mineral deposit department has researched it as the typical boreal karst groundwater. The research of balancing experiment of Yangzhuang basin in the city of Zaozhuang by the third hydrological team of province has been on several years and accumulated lots of basic materials and physical measured data. Owing to the complex nature of the groundwater resources system far beyond that of surface water system, the detailed investigationwork to the whole basin has not been finished and much work has stayed in the lever of artificial operation, Which limited in the time and effect nature and scientific approach. This article try to use relational function of GIS to research and analyzc the development of groundwater resources in this basin based on the work of predecessor. The whole article is divided into six parts: 1. Regional general situation. Discussion of the terms which influenced groundwater resources, such as iandform, terrain, climate and hydrogeology, et, and the constrained effect of these terms to thedevelopment of groundwater resources. 2.Build the database of analysis of the development of the groundwater resources. Input the attributive data and special data respectively, attributive data include all basic data and relational data derived from them, while the special data collected stratifiedly through the numberlization of map arc used in special analysis and to build thematic map. 3. Analytic conclusion of the development of groundwater resources is: the water quality of groundwater resources is not principally suffered from artificial pollution; the characteristics of the development of groundwater lever is: supplying in short time and drainage throughout the entire year in the time level, supplying separated in large areas and drainage conccntratively in space. Groundwater has large store space and has the adjustable effect of many years, and groundwater resources are in the dynamic balance: the perennial supply is balanced with perennial drainage. 4. he calculation of the quality of water resources and the forecast of supply and demand show that the groundwater has not appeared gaps. With the increase of the quantity of social demand or come across with the drought years, there will appear the problem of supply doe not meet with demand. If the frequency of precipitat ion is 75% in the year of 2000 and 2010, the deficitwill be 1.314 km3 and 2.738 km3 respectively. if we extract water blindly in order to meet with demand, there will easily he overexploited and a series of others harmful geological environmental disasters. 5. It is of great urgency to reinforce the management of water resources. Surface water and groundwater should be exploited synthetically and controlled combinedly, during which the stresses are the increasing of the quantity of groundwater supply and broaden the sources of income and economize the expenditure, furthermore, water resources fled vainly in the flood season and wasted in the irrigation of extensive cultivation should be retained , stored or changed frito groundwater; building long ime inspect and control system of water quality and quantity, supplying the information of water resources in time; engineering in the upper, middle and lower leaches of rivers should be matched, development, utilizati...
