摘　　要：从成都出发,经都江堰到汶川映秀,进入中国熊猫大道,在小金县域段沿小金川两岸发育复杂褶皱图案的砂岩与板岩呈韵律互层的陡倾岩层,这就是小金复理石地质景观,为松潘-甘孜造山带复理石岩系的典型地区,极具视觉震憾力,也是申报四姑娘山世界地质公园核心地质遗迹群落之一。通过对小金复理石景观的地层结构、复理石沉积特征、赋存的古生物化石、叠加发育的西康式褶皱等综合分析,以及与世界典型西班牙复理石崖岸景观对比,确立了小金复理石景观的价值意义,从而奠定了小金复理石景观为世界级地质景观的地位。在此基础上对小金复理石地质景观提出可持续保护利用的措施建议。From Chengdu,through Dujiangyan to Wenchuan Yingxiu,and the China Panda Avenue,in the Xiaojin County section along the banks of Xiaojinchuan complex folding patterns of sandstone and slate in the rhythm of the steep rock formation,this is the Xiaojin flysch geological landscape.It is a typical area of flysch rock series in Songpan-Ganzi Fold Belt,which has great visual shock and is also one of the core geological heritage communities of Siguniang Mountain Global Geopark.Through the comprehensive analysis of the stratigraphic structure,flysch sedimentary characteristics,paleontological fossils and superimposed Xikan-type folds of Xiaojin flysch landscape,as well as the comparison with the typical Spanish flysch cliff landscape in the world,the value and significance of Xiaojin flysch landscape are established,thus establishing the position of Xiaojin flysch landscape as a world-class geological landscape.On this basis,the sustainable protection and utilization measures of Xiaojin flysch geological landscape are proposed.
