The first part of this project investigated and evaluated the environmental quality of Shihmen Reservoir Stream Ecosystems. This study done the Stream habitat survey and biodiversity survey at Baishih River, Karla River, Siayun River and Yising power factory as sampling sites and set each site 3 sampling locations. Compared with former studies, this project found that during constructions the turbidity and suspended solids(SS) showed significant disturbance. This study also found that we can use freshwater fishes and aquatic insects as indicator organisms. This project done the ecological quality assessment with 9 evaluation of habitat environment methods, the result showed that aquatic insects index of RBP III, CQHEI and RBP are relatively sensitive. This study proposed the RBP evaluation of habitat environment is the most practical method for use, for its sensitivity and representability.
The second part of this project aimed to normalize ecological conservation on the management of catchment area of reservoirs. This study modified the “Ecological Survey & Assessment Specification on the catchment area of Shihmen Reservoir”, the manuscript made by the Water Resources Agency. This study had made several modifications in order to applied in the real situation, such as the establishment of norms of data sorting method, establishment of standard operating procedures for the whole specification, simplification of assessing methods, simplification of forms and procedures. This project also studied the differences between conservation constructions and their ecological significances, the engagement possibility of ecological experts and the proposition of evaluating systems and feedback by the cases this project surveyed.
