摘要
位于大英县回马镇的壶穴群景观带发育面积约12×10~4m~2,从壶穴演化发展直至消亡,形成了众多典型和稀有的水流侵蚀微地貌景观,它集中成片状、沿着涪江曲流的凸岸连绵展布,成千上万个壶穴贯通后,如“千帆竟舞”般的侵蚀石垄与石槽相间,描绘出涪江大英段连绵起伏、波澜壮阔的美丽画卷,是目前已知形成于宽缓河床基岩上、具有典型流水侵蚀特征、微地貌景观群规模最大、分布最集中的壶穴群景观带,具有极高的典型性、稀有性和美学价值。
The pothole landscape zone in Huima Town,Daying County covers an area of about 12×104m2.From the evolution of potholes to their extinction,many typical and rare water erosion microgeomorphic landscapes have been developed.It is concentrated in sheets and distributed continuously along the convex bank of the Fujiang River.Thousands of potholes are connected,describing the magnificent beautiful picture of the Fujiang River in Daying Conuty.The pothole group is a landscape zone with the largest scale and the most concentrated distribution of microgeomorphic landscape group,which is formed on the bedrock of broad and gentle riverbed,and has the characterisctis of high typicality,rarity and aesthetic value.
