摘要
吉林省靖宇自然保护区富含天然矿泉水资源并发育火山群,为了调节水资源、科学开发合理利用和保护矿泉水资源,利用GMS软件根据研究区内钻孔资料以及已有的地质水文地质条件建立了靖宇自然保护区的三维地质结构模型,但此模型不能真实的反映出研究区特有的火山群地貌,因此又利用MAPGIS软件根据研究区地形图矢量化的等高线建立了DEM数字高程模型,DEM模型能较清楚地反映研究区地面的真实信息。因此基于DEM模型的三维地质结构模型不仅能模拟研究区地层情况,还能清晰地模拟出研究区地表起伏状况,尤其是对火山群地貌的模拟。这两种模型的结合为地形起伏较大、地形较复杂地区难模拟的问题提供了一种解决方法。
Mineral water resources and developed volcanic group is rich in Jingyu Nature Reserve of Jilin Province. According to bore- hole data of study area, GMS software is used in this paper to establish three- dimensional model of geological structures of Jingyu Nature Reserve for the adjustment of water resources, scientific development and reasonable use and protection of mineral water re- sources. However, the unique volcanoes landscape of study area can not be really reflected in this model. Therefore, according to the vector of the contour of the study area topographic maps, the MAPGIS software is used in this paper to establish DEM digital eleva- tion model. The real information of the ground of study area is clearly reflected in DEM model. So the three- dimensional model of geological structures based on DEM model can simulate not only the stratigraphy of study area but also the status of terrain of study area, especially the volcanoes landscape. A new solution is provided with the combination of the two models for the difficulty of sim- ulation in relatively big ups and downs of terrain area and complex terrain area.
