| 摘 要： | 本文在前期资料收集和资源环境承载力评价的基础上,结合威海市当地地质特征,选择地质环境条件、地质环境问题和人类工程活动作为一级评价指标,地形地貌、地下水资源、区域地壳稳定性、地质灾害、地下水污染、海水入侵、人口密度、农业活动、矿业活动作为二级评价指标,采用层次分析法和模糊数学法对威海市地质环境质量进行综合评价。研究结果表明:区内地质环境质量划分为优等区、良好区和中等区3个级别。总体来说,研究区地质环境质量较好,优等区面积3278.97km~2,在研究区广泛分布,约占研究区总面积的56.66%;良好区面积2493.09km~2,分布在环翠区北部、文登区西部、乳山市北部及荣成市东部地区,约占研究区总面积的43.01%,中等区仅小范围分布威海市市中心一带,面积24.94km~2,约占研究区总面积的0.43%。

| Abstract: | Based on previous data and environmental carrying capacity assessment, combining with local geological characteristics in Weihai city, choosing geological environment background conditions, geological environment problems and human engineering activities as the primary evaluation factor, choosing landform, groundwater resources, regional crustal stability, geological disasters, seawater intrusion, groundwater pollution, population density, agriculture and mining activities as the secondary evaluation factor, by uisng analytic hierarchy process (AHP) and fuzzy mathematics method, geological environment quality in Weihai city has been evaluated. It is showed that geological environment quality can be divided into three grades, they are excellent area, good area and medium area. Geological environment quality of the study area is generally good. The excellent area covers 3278.97km2 and distributed widely, and accounting for about 56.66% of the total area. The good area covers 2493.09km2, and accounting for about 43.01% of the total area. It is distributed in the north of Huancui, the west of Wendeng, the north of Rushan and the east of Rongcheng. The medium area only covers a small area around the center of Weihai city with an area of 24.94km2, and accounting for about 0.43% of the total area. |
