For basic references of ecology and water qualities in the Jhong-gang stream, the Ke-ya stream and the Nan-kan stream have been collected in this project. In the past one year, this team has conducted field investigation and has established an ecological river data bank for this area. By means of GIS, the environmental protection index and the references for management have been provided. The items, which have been completed in this project, are as follows. 1. The aqua organism resources and its distribution of the Jhong-gang stream, the Keya stream and the Nan-kan stream have been established as references for further organization. It has also been understood that the water pollution status has influenced the distribution of the living aqua organism. 2. The organism index for monitoring water qualities of the Jhong-gang stream, the Ke-ya stream and the Nan-kan stream has been established, that may be a basis to evaluate the water qualities. These methods may be provided to students and the general public. 3. To cooperate with the water pollution improvement of the Jhong-gang stream, the Ke-ya stream and the Nan-kan stream, the feasible goals of river basin ecology have been made and the suggestions for restoration of bio-diversity in the river basins have been given. 4. The teaching and applied materials of monitoring index organism of the Jhong-gang stream, the Ke-ya stream and the Nan-kan stream have been established and some teachers and students have been trained to have abilities to use the index of environmental aquatic organism. 5. The database of environmental aquatic organism of the Jhong-gang stream, the Ke-ya stream and the Nan-kan stream has been made. 6. To assist judgment of possible reasons of sudden death of aqua creatures. It might be helpful to find out possible resources of water pollution.
