摘要
永靖县域共厘定地质遗迹资源42处,涵盖了地质遗迹的三大类型,主要包括基础地质大类7个,地貌景观大类33个,地质灾害大类2个。其中世界级1处,国家级5处,省级7处,省级以下29处。永靖县地质遗迹资源以丹霞地貌为主,地质遗迹点整体呈现沿黄河两岸中心廊道密集、东西零星分布的特点。黄河两岸地质遗迹资源点占全部地质遗迹点的80%;东部沿道路镇乡分布,较为稀少,占全部地质遗迹点约16%;西部零星分布几个地质遗迹点,占比最少,约4%,呈现地质遗迹资源点分布极不均匀现象。主要成因是受到区域构造影响和后期地壳升降运动等地质作用改造。在开发利用中要保持原有地形地貌格局,要发挥地质景观的造景功能。岩石、地层、峭壁、峡谷、水体可以构成永靖山水城市街景中的重要点缀。
A total of 42 geological heritage resources have been determined in Yongjing County,covering 3 major types of geological heritage,including 7 basic geological categories,33 geomorphic landscape categories,and 2 geological hazards categories,mainly Danxia landform,of which 1 is world-class,5 are national,7 are provincial,and 29 are below provincial level.The geological heritage sites in Yongjing County as a whole show the characteristics of dense central corridor along the Yellow River and scattered distribution from east to west.The geological heritage resource sites on both sides of the Yellow River account for 80%of all the geological heritage sites.In the east,the towns and townships along the road are relatively rare,accounting for about 16%of all geological sites.In the west,several geological heritage sites are scattered,accounting for the least,about 4%,showing a very uneven distribution of geological heritage resource points.It is mainly due to the regional tectonic influence and the late crustal movement and other geological processes.In the later stage of redevelopment and utilization,the original landform pattern should be maintained,and the function of geological landscape should be brought into play.Rocks,strata,cliffs,
