碩士 / 國立交通大學 / 土木工程學系 / 98 / The study uses the data utilized Delphi Method to choose indicator organisms from「Study the Ecological and Environmental Monitoring and Evaluation of Stream Project on the Tributaries of the Shihmen Reservoir」. During the process, we invite many experts to fill in questionnaires, revise questionnaires constantly, and publish questionnaires to choose the rank of indicator organisms of Shihmen Reservoir’s catchment area. To investigate the rank of foregoing indicator organisms and another one according to accompanied richness and frequency. Then, we decide to use two methods of biological indicators of the scope further.
The study range of the article chooses seven streams in reservoir’s catchment area, uses Delphi Questionnaire and accompanied richness to decide indicator organisms. We understand that the first and second of the rank of indicator organisms are Acrossocheilus paradoxus and Scaphesthes barbatulus. It is a negative relationship between the rank of questionnaires and accompanied richness, Pearson correlation is -0.606～-0.952. It is a positive relationship between the rank of questionnaires and frequency, Pearson correlation is 0.477～0.894. It shows that indicator organisms belong to frequent species chosen by questionnaires, and have high tolerance in variety of habitat conditions. So, restoring Acrossocheilus paradoxus and Scaphesthes barbatulus is more easier.
The species with higher accompanied richness chosen by accompanied richness has lower frequency of occurrence. Because of lower frequency of occurrence, the demand of habitat conditions is usually more stringent. Above mentioned, we create the habitat which can satisfy the most of the biological needs of the habitat conditions and effect the habitat of species diversity.
