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 in queue on " sustainable development " around national and international range , 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 of changeable 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 boosting up 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 基于以上考虑,论文主要从以下几方面对地下水资源可持续开发问题进行了比较深入的探讨:全面回顾了“可持续发展”概念的由来与演变,对国内外“可持续发展”的研究现状进行了述评,并对“可持续发展”概念的科学内涵进行了深入探讨;对涉及地下水资源的一些最基本的概念和命题进行了全面的回顾和评述,对目前仍然存在的一些错误观点和混乱认识提出了自己的见解;全面阐述了地下水资源变值系统理论的内容和意义,并与传统的地下水资源计算评价方法进行了对比分析,结合实例具体说明了方法的应用;深入分析了地下水资源预测预报工作的极端重要性和复杂性,对传统的地下水资源动态预测方法进行了全面的评述,指出了各类预测预报方法的特点及适用条件,对最近二十多年刚发展起来的小波分析技术的主要思想和方法及其应用范围,以及号称第五代计算机语言的matlab软件和附带的小波分析工具箱进行了介绍,并应用于地下水动态过程线的分析,采用时间序列中的b ? j法,蒙特卡罗方法,与地下水资源变值系统理论相结合,探讨了地下水动态资料分析和地下水资源预测预报的新思路;综合分析了现今各类地下水管理模型的特点及缺陷,将数学规划、数理统计、随机过程等与地下水变值系统理论相结合进行地表水地下水或多水源的联合优化调度,使模型更准确、更实用;对保证地下水资源可持续开发的内部条件和外部条件进行了分析,内部河海人学博卜学位论文前言、摘要、目录条件主要是正确的资源观,科学的资源计算与评价方法,可靠的资源预测预报技术,可操作的资源管理措施,外部条件主要是高层发展思路、管理体制的变革、配套的政策法规、经济杠杆的调节、人文素质的提高、节水意识的增强及具体节水措施、人口增长的控制、水体污染的防治、生态的恢复和重建等;从宇宙科学、地球系统科学及哲学的高度审视地下水资源的可持续开发;指出了地下水资源可持续开发的进一步研究方向。
