| Research Abstract |
The environmental management has gained much importance in river management in recent years and further promotion of environment-friendly management of rivers is being encouraged. However, various elements on the geography, the biology and the social science are related complexly to the riparian environment. We examined the system for the riparian environment of four rivers in the Asian Monsoon climate zone. River improvement works were executed in the Chino River by restoring the fireflies' natural environment in the new channel. According to the monitored results on the recovery of vegetation, birds, fireflies and small animals, the environment has been restored and the number of flights of fireflies was almost the same as the number before the river improvement works. The monitored results suggested that the river improvement works had been relatively well executed to conserve the habitat of the firefly. In order to evaluate objectively, the riparian environment of the ten rivers in Miyazaki and Okinawa were classified by means of the multivariate analysis. The physical element, the biotic element, the chemical element, and the sensuous element were used as the evaluation items on the riparian environment. All observed points of the Chino River were evaluated in good quality, but in the state influenced by human activities due to the river improvement works.
From these results, in the rehabilitation of the environment in the river where the river improvement was executed the impact to the river environment, it is necessary to improve the physical environment according to the monitored results.
