四川道孚八美糜棱岩石林形态特征及综合评价

Morphological characteristics and comprehensive evaluation of the Bamei mylonite hoodoos in Daofu County,Sichuan

八美石林是在青藏高原东侧首次发现的、国内唯一的糜棱岩石林,可与南方喀斯特石林景观相媲美,在地质成因和自然环境等方面具有特殊性。对石林形态的划分,尤其是对糜棱岩石林形态的划分,国内目前还没有统一的标准。本文从糜棱岩石林的地貌形态、相对高差及旅游美学的角度,将八美糜棱岩石林初步划分为尖棱状、刀刃状、石墙、石柱、石槽、金字塔状及钟状等七种类型,这对研究糜棱岩石林的成因及综合评价具有重要意义。

Bamei hoodoos, located on the eastern side of the Qinghai-Tibet plateau, is only mylonite hoodoos discovered in China. The Bamei mylonite hoodoos, which can be compared with the karst stone forest, has a unique geologic origin and natural environment. The classification for stone forest, especially for mylonite hoodoos, has had no consensus in China at present. In this study, the Bamei hoodoos is divided into seven types based on geomorphology, relative elevation and tourism aesthetics perspective： sharp edged, blade-shaped, stone walls, stone pillars, stone trough, pyramid-shaped and bell-shaped. This study has important implications for the research of the genesis and comprehensive evaluation of mylonite hoodoos.
