Summary: | 碩士 === 國立交通大學 === 土木工程系所 === 96 === Under the continuing forever management of ecological engineering, it should avoid or abate the ecological destruction when the coasts develop, or the existence space necessary to be commuted and atoned. It is called the mitigation, that is, the ecological evaluation should be preceded before the construction of the habitat, and the ecological habitat should be restored when the construction completed. Therefore, HEP is more often to be used for mitigation.
It is different to control HEP by simply utilizing the ecological indicator (example: Shannon-Wiener species diversity). The paper uses the target of habitat by more complete and perfect B-IBI. In one side, we can monitor B-IBI of the environment by HEP. In another side, we can lay the alternative plan by HSI.
The source of building B-IBI value by foreigner is different from Taiwan. Therefore the paper revises the B-IBI value by referring the locality data of Coast of Chang-Hua Fang-Yuan, Gao-Mei wetland and Tai-Nan An-Pin fishing port. The scored interval utilizes the method of the water quality that is according with the reference site, and then cooperates to divide by the data of researching area. The revise of pollution-indicative taxa of B-IBI value is not through the searching of literature in the world but through biological data in this researching area. Finally, in the calculating result from 82 kinds of benthic, there are 10 kinds of benthic belonging to low indicative (L), 48 kinds of benthic belonging to middle indicative(M), 34 kinds of benthic belonging to high indicative(H).
