%X Based on heavy mineral analysis, the sediment originated from lower reaches of the Daguhe River was studied. We found that the characteristics of heavy mineral were different between the Xiaoguhe River and the upper reaches of the Daguhe River. The high content of hornblende was the feature in upper reaches of the Daguhe River and the contents of ilmenite and epidote were also high. In contrast, main heavy mineral assembled was mixed by hornblende, epidote, tremolite and garnet in the Xiaoguhe River and the lower reaches of the Daguhe River. In addition to similar relative contents for most heavy minerals, mineral shape characteristics and mineral species were also identical. These results illustrate the major sediments of the lower reaches of the Daguhe River come from its main branch, the Xiaoguhe River. Therefore, conservation of soil and water in the Xiaoguhe River drainage area is key to maintain and restore the sedimentary environment in the Daguhe Rever watercourse and the Jiaozhou Bay.
