Analysis and inspiration of the Geomorphic Units Survey and Classification System(GUS)in the European Union
River geomorphology is the key to natural habitat assessment,the investigation and assessment of river geomorphology units play an important role in river ecosystem protection and restoration.To better identify diverse geomorphic unit types,assess channel complexity and habitat potential.The results of the Geomorphic Units Survey and Classification System(GUS)proposed by EU are reviewed from three aspects:multi-level geomorphic unit classification framework,multi-level geomorphic unit survey technology system and geomorphic unit diversity assessment.The applicability of GUS system in river geomorphology investigation in China is proposed.The Yudong River in Chishui River basin is taken as an application case of GUS system to classify and identify the geomorphology units of Yudong River.GUS is a good guide and reference for the restoration and integrated management of river habitat in China.
