The area of experimental watershed was 3.33 ha, and the thorny bamboo was a superior species, which located in the southwestern side of the comprehensive district of soil and water conservation of National Pingtung University of Science and Technology, Taiwan. The open terrace was close to midstream region of valley line in a constricted area and reclaimed within width and length of 6m and 8m, without any canopy on ground surface in initial stage. All the investigation was to implement from June to October, 2015. The result had shown the variation of cover rate in 10 days, 31 days and 112 days were 24.9% 、35.9% and 80.7%, respectively. There was no woody plants on the ground surface in watershed during investigation period. Key Words: Cover rate, watershed, thorny bamboo plantation. 〔1〕國立屏東科技大學水土保持系副教授 （* 通訊作者 E-mail: tangchi@npust.mail.edu.tw ） Associate professor, Department of Soil and Water Conservation , National Pingtung University of Science and Technology, Neipu, Pingtung, Taiwan. 〔2 〕國立屏東科技大學水土保持系碩士生 Graduate student, Department of Soil and Water Conservation, National Pingtung University of Scie
