Research Of The Karst Groundwater System

The thesis analyses the karst groundwater owing to the system scientific theory and method , the concept and karst groundwater system research having discussed karst groundwater system respond to the content including main part, is tied in practical and actual research owing to that groundwater carries out theory to karst groundwater system and their karst studying the content theory choosing the example area—northern Wei River, priority has studied the systematic structure and water circulation characteristic of the karst groundwater of northern Wei RiveraAccording to the karst system still belongs to a concept in developing , the pre research according to the karst groundwater accounts differ and opinions vary, modern system theory-based thought of thesis , the pre research result, be tied in cognition having studied understanding in working , having brought forward my understand of karst groundwater system concept. I think: Karst groundwater system has two inalienable parts that are mutual connections, mutual restraint, between karst groundwater space and karst water circulation, some relatively independent geology element continua constituting but being accomplished according to certain law.So-called "karst groundwater space" is the structure of karst groundwater system, it is karst-rization tier of group and geology structure organic combination going ahead in space containing multiple water medium. It is that karst groundwater system keeps whose globality and has definitely functional inherent basis."Karst water circulation " also called karst streams system , is to refer to transmission , change of complicated matter and energy in the karst groundwater system , including runoff and drainage overall process. The systematic karst groundwater function is to come true by karst water coming circulation.Because there is no united cognition of systematic research responds to the content including that content still having , the author responding to main part including to the person at present to karst groundwater have brought forward self view. I think there should be three aspects of the research of karst groundwater is really entirely and scientifically. This content in three aspects is: (1) the main enviromental effect factoring karst groundwater; (2)the structure of karst groundwater system; (3)the circulation characteristics of karst groundwater water system.The thesis is known with the above-mentioned theory to karst groundwater system and their content studying , is applied to the research carried out in the example area-east of the northern karst groundwater of Wei River, priority has studied structure and water circulation characteristic of the northern karst groundwater of Wei River. In the studying of the "structure" character, has analysed the stratum that karst groundwater stores and their rock nature character; Karst form; the nature of stratum rock, geologic structure charge the water characteristic as well as the hydrology catches with a hydro net. I divide the section into rich water section of an area and rich water of prospect on the basis studying in analysis. In the studying of Dynamic field, comprehensive analysis has studied the isotope characteristic and the water chemistry , has revealed an example studying the characteristic of water circulation in karst groundwater of the east northern Wei River: Exposed carbonas rock area is that the karst water directness supplies area in the western part, the earth's surface wave is that the maximum supplies a source , whose shallow periphery covered area is indirect supply area; Karst water accepts provision in the thing on direction, in western part , self west smooths as a whole comparatively to east runoff; On north and south direction, accept provision in central section, shunt running to north and south two flanks runoff.The thesis takes karst groundwater of east northern Wei River as an example to carry out actual theory union research, not only the problem having expounded and proven what be suggested that karst groundwater system research theory, moreover the research result exploitation to karst groundwater of Wei River applies value with protecting a job living in important reality.
