遥感技术在张家界砂岩峰林地貌成因研究中的应用

应用遥感技术对张家界砂岩峰林地貌进行研究,新解译出叠加于北东东向褶皱之上的北北东向褶皱及线性构造1031条,并提出本区经历了两次以上褶皱构造运动的新认识；查明了砂岩峰林地貌的形成与地质构造之间的关系,并对其形成机理进行了探讨。通过解译研究,认为中上泥盆统巨厚层石英砂岩是形成砂岩峰林地貌的物质基础；特殊的构造部位有利于峰柱的稳定形成；多次构造作用所产生之高角度裂隙有利于峰林地貌的造型；挽近时期的地壳抬升是峰林地貌形成的动力因素。

APPLICATION OF REMOTE SENSING TO SANDSTONE FOREST LANDSCAPE INVESTIGATION IN ZHANGJIAJIE

Remote sensing technique was applied to the investigation of the sands- tone forest landscape in Zhangjiajie. It is newly confirmed that NNEtrend fold repeaded on the NEEtrend fold, and 1031 lineaments were first interpreted. Anew knowledge was suggested that this area was undergone more than twice fold structural movements. The relationship between the formation of sandstone forest landscape and geological tectonic was ascertained.It’s mechanism of formation was explored. It is considered that Devonian system (upper and middle series) huge thick quarty sandstone is the material foundation for forming sandstone forest landscape) the particular tectonic position favoured the formation of sandstone pillar steady; several times tectonic processes producing high angle fracture favoured sandstone forest landscape modelling; the neoid crustal uprising is the driving power for the formation of the sandstone forest landscape.
