Previous researches had emphasized tectonic impacts on the fluvial system at the tectonically active areas, while the effects of lithology and local base level change have received relatively rare attention. Here we investigated fluvial landforms at di

对野外实测数据进行反演解释之前,需要对原始数据的形态和存在的问题有充分的认识,并作相应的预处理。因此,本文结合广西地区实际观测点所处地质条件构建若干模型,进行矢量有限单元法大地电磁三维数值模拟,首先讨论视电阻率ρ_(xy)和ρ_(yx)的变化规律及差异;其次,探讨ρ_(xx)和ρ_(yy)反映的地电信息;再次,模拟静态位移产生的条件。从算例中得出几点认识:对于同样的地质构造,ρ_(xy)和ρ_(y

地质公园作为一种新型的旅游产品,是地质科普和地质旅游的有效结合体。自2000年开始,我国地质公园进入高速发展阶段,截止至2019年10月,国家林业和草原局和原国土资源部通过了八批共275处国家地质公园。然而我国地质公园的开发主要集中在旅游地质资源的商业价值开发中,缺少对地质资源科学价值的开发,地质公园科普教育和科学研究功能相对欠缺。
