Study The Sustainable Development Of Groundwater Resources Based On The Theory Of Changeable System

Along with the speediness development of economy and sociality, fresh water resources become the one of three world key problems coordinated with energy sources and food supplies. As the important part of fresh water resources, the sustainable utilization of groundwater resources was more and more come in for attention by international sociality at large. To study the sustainable and optimum exploitation of groundwater resources has not only the important realistic meaning, but also the far-reaching historic meaning. It shall provide the science evidence for establishing the sustainable development goals and stratagem decision-making of water resources, and the theory foundation for establishing the sustainable development stratagem of economy and sociality. Based on consider hereinbefore, this dissertation discusses several aspects on the problem of the sustainable and optimum exploitation of groundwater resources as follows:(1)reviewed entirely the origin and evolvement of the concept"sustainable development" , stated and commented the study status inqueue on "sustainable development" around national and internationalrange, thorough discussed the science connotation about the concept "sustainable development" ;(2)looked back and commented across-the aboard some furthest basic concept and proposition related to groundwater resources, put forward self opinions on a few existent mistake points of view and chaos understandings;(3)expatiated entirely on the content and meaning of the theory ofchangeable groundwater resources system, contrast with the traditional methods of groundwater resources calculation and evaluation, combined example to show the application of this theory;(4)thorough analyzed the difficult and complexity to forecast the groundwater resources, fully stated the traditional methods of groundwater resources forecasting, pointed out the characteristic and applying condition of these forecasting method, introduced the main ideas and methods of wavelet analysis developed recently, and the MATLAB software be known as the fifths era computer language, and its accessory wavelet analysis toolbox, applied these methods and tools to analyze the groundwater dynamic curve, adopted the B-J method and Morte-Carlo method, combined with the theory of changeable groundwater resources system, discussed the new view on the forecast of groundwater resources;(5)synthetically analyzed the characteristics and limitations of the present all kind of groundwater manage model, combined mathematical programming mathematical statistics random process and the theory of variation system of groundwater resources on the unite optimum attempter of surface water and groundwater, emphasized how to make the model more nicety, more simple, more practicality;(6)analyzed the inside condition and outside condition to assure the sustainable and optimum exploi tation of groundwater resources, the inside conditions are the follows: correct resources idea, scientific methods of resources calculation and evaluation, credible forecast methods of resources, exercisable measures of resources management, the outside conditions are the follows: the development idea of high layer, the transform of manage system, the matched policy and rule of law, the adjusted of economy lever, the improve of cultural diathesis, the boostingup of water-saving consciousness and detail measures, the control of population rising, the prevention and cure of water pollute, the renew and rebuild of ecology;(7)scan the sustainable and optimum exploitation of groundwater resources from the high level of metagalaxy, earth system science, and philosophy;lint out the more directions on groundwater resources.
