摘要
梅岭景区地处江西中北部,南昌市西侧,是发育典型的花岗岩地貌景观,该套花岗岩主要形成于新元古代青白口纪,如此古老的花岗岩地貌景区在世界范围内相对少见。按照地貌的规模和特征,可以将研究区划分出3种尺度和17个地貌类型和现象。地壳抬升等引起的夷平事件是宏观地形的主要控制因素,与我国华南大部分花岗岩地貌景观形成过程类似。研究区主要经历了古近纪和第四纪的2期夷平作用,但景观地貌的多样性和独特性主要与岩浆结晶分异作用和结晶速率差异性导致的岩体相变和成层性等以及成岩后期的次级改造有关。梅岭景区属花岗岩地貌演化的壮年晚期阶段,具有较高的美学和科普价值。
Meiling scenic area is located in north and medium part of Jiangxi province, and west side of Nanchang city, is a typical granite landscape, The granite is mainly formed in Qingbaikou Period of Neoproterozoic, so ancient granite landform scenic area is relatively rare in the world. According to the scope and character of the landscape, the author can divided into 3 kinds of scales and 17 geomorphic types and phenomenon-large scale terrain. Similar to granite landscape forming process of most of southern China, the study area mainly experienced two phases planation in paleogene and quaternary. There are many aesthetics and scientific values in Meiling scenic area.
