【摘要】：山东省鲁西北地区地处黄河下游冲积平原地带，，饮用水源主要为地下水。由于该地区特殊的地质条件，地下水中氟、碘含量普遍偏高，易造成水源性氟、碘中毒，是受地氟病、地碘病危害比较严重的地区。为了保障该地区人民饮用水安全，减少地方病的发生，山东省国土测绘院开展了“山东鲁西北地区高氟高碘区地质环境调查与供水评价示范”项目。本论文依托于该项目对工作区的地下水资源进行分析评价，了解氟、碘分布规律，为各地寻找合适的饮用水源提供科学依据。本论文先是在充分了解工作区的水文地质条件后，参考以往的研究成果，选用了合适的水文地质参数对工作区内的浅层、深层地下水进行了资源量均衡计算，均衡分析的结果显示工作区浅层地下水基本处于均衡状态，计算所选的参数准确可靠。根据计算结果确定了工作区浅层地下水的供水能力:西北及东南地区供水能力较弱，中部的地区供水能力较强；深层地下水供水能力由东南向西北逐渐增强。然后根据野外调查工作所取的区内的175眼浅水井及75眼深水井的水质分析结果，按氟离子、碘离子、矿化度的不同分别对工作区进行水质分区，确定深、浅层地下水的氟、碘、矿化度分布情况，综合这三项数据确定出水质达标区域的范围，并计算其地下水资源量。浅层水质达标区比较分散，主要分布在聊城市、高唐县、冠县以西、东南沿黄一带；深层水质达标区分布较集中，主要在东南沿黄一线附近。最后在综合分析工作区深、浅层地下水氟、碘矿化度分布情况后，得到工作区的供水规划方案：西北部德州、武城，冠县以东及东南的范县附近深、浅层地下水质都较差，适合饮用地表水；冠县以西、聊城及高唐县附近浅层地下水质较好，可作为饮用水源；东南沿黄一线深层地下水质好，适合作为饮用水源。本次的成果对工作区寻找合适的饮用水源，减轻地方病的发生有重要的参考价值。
[Abstract]:The northwest region of Shandong Province is located in the alluvial plain of the lower Yellow River. The drinking water source is mainly groundwater. Because of the special geological conditions in this area, the content of fluorine and iodine in groundwater is generally on the high side, which is easy to cause water source fluorine and iodine poisoning. In order to ensure the safety of drinking water and reduce the occurrence of endemic diseases, Shandong Land Survey Institute carried out a demonstration project of "Geological Environment Survey and Water supply Evaluation of High-Fluorine and High-iodine areas in Northwest Shandong Province". This paper is based on the project to analyze and evaluate groundwater resources in the working area to understand the distribution of fluorine and iodine and to provide scientific basis for finding suitable drinking water sources. After fully understanding the hydrogeological conditions of the working area and referring to the previous research results, this paper selects appropriate hydrogeological parameters to calculate the resource balance of shallow and deep groundwater in the working area. The results of equilibrium analysis show that the shallow groundwater in the working area is basically in equilibrium state and the calculated parameters are accurate and reliable. According to the calculation results, the water supply capacity of shallow groundwater in the working area is determined: the water supply capacity of the northwest and southeast regions is weak, the water supply capacity of the central region is stronger, and the water supply capacity of the deep groundwater gradually increases from the southeast to the northwest. Then according to the results of water quality analysis of 175 shallow wells and 75 deep wells in the field investigation work, according to the different degrees of fluorine ion, iodine ion and mineralization, the water quality of the working area was divided, and the fluorine and iodine of the deep and shallow groundwater were determined. On the basis of the distribution of salinity, the range of water quality standard area is determined by synthesizing these three data, and the groundwater resource quantity is calculated. The shallow water quality reaches the standard area is dispersive, mainly distributes in Liaocheng, Gaotang County, Guanxian west, southeast along the Yellow River, the deep layer water quality standard area distribution is relatively concentrated, mainly near the southeast along the Yellow River. Finally, after the comprehensive analysis of the distribution of fluorine and iodine mineralization in the working area, the water supply planning scheme of the working area is obtained: deep near Fan County in northwestern Texas, Wucheng, east and southeast of Guan County, and worse in shallow underground water quality. It is suitable for drinking surface water; to the west of Guanxian, Liaocheng and Gaotang County, the shallow underground water quality is better and can be used as drinking water source; The results have important reference value for the work area to find suitable drinking water source and to reduce the occurrence of endemic diseases.
