【摘要】：地质环境是人类赖以生存的自然环境的重要组成部分,地质环境质量限定着人类工程活动的强度,因此开展区域地质环境条件评价,对于制定区域土地利用和社会发展规划,促进地区的可持续发展具有重要的现实意义。随着社会经济发展和生产力不断提高,人类工程活动强度越发强烈,工业、农业污染物的排放造成地下水质量变差、污染日趋严重,诱发的地质灾害给居民生命和财产带来安全隐患。因此,从可持续发展和加强生态文明建设考虑评价地质环境,意义重大。本文以吉林省延吉市朝阳川地区为研究区,系统分析了该区的水文地质条件和工程地质条件,并分别按照地下水类型及富水性和工程地质特征进行了分区;在上述工作的基础上开展了地下水质量评价、地下水污染评价、地质灾害危险性评价以及土壤污染、水土流失等评价,综合分析了主要环境地质问题的危害性、危险性;最后提出了地质环境保护和防治的建议。通过本次地质环境评价,确定延吉市朝阳川地区孔隙潜水质量较差、污染严重、可利用资源量小,孔隙裂隙水资源量分布不均,地下水环境受人类工程活动影响较大;人类工程活动诱发地质灾害日趋严重,但因其规模有限,危险性不大。总体而言,该地区地质环境脆弱,开发利用的同时一定要加强保护。
[Abstract]:Geological environment is an important part of the natural environment on which human beings depend for survival. The quality of geological environment limits the intensity of human engineering activities. Therefore, the development of regional geological environment condition evaluation is of great importance to the formulation of regional land use and social development planning. It is of great practical significance to promote regional sustainable development. With the development of social economy and the continuous improvement of productivity, the intensity of human engineering activities is becoming more and more intense. The discharge of industrial and agricultural pollutants causes the quality of groundwater to deteriorate and the pollution to become more and more serious. The induced geological disasters bring safety risks to residents' lives and property. Therefore, it is of great significance to evaluate the geological environment from the view of sustainable development and strengthening the construction of ecological civilization. Taking Chaoyang Sichuan area of Yanji City, Jilin Province as the study area, the hydrogeological conditions and engineering geological conditions in this area are systematically analyzed, and the groundwater types, water-rich and engineering geological characteristics are divided respectively. On the basis of the above work, the evaluation of groundwater quality, groundwater pollution, geological hazard, soil pollution and soil erosion are carried out, and the harmfulness and danger of the main environmental geological problems are comprehensively analyzed. Finally, some suggestions for geological environment protection and prevention are put forward. Through this geological environment evaluation, it is concluded that the quality of pore phreatic water in Chaoyang Sichuan area of Yanji City is poor, the pollution is serious, the amount of available resources is small, the distribution of pore fissure water resources is uneven, and the groundwater environment is greatly affected by human engineering activities. Geological hazards induced by human engineering activities are becoming more and more serious, but they are not dangerous because of their limited scale. In general, the geological environment in this area is fragile, development and utilization must be strengthened at the same time.
