Since each engineering method will cause an impact on the environment [1], a handy tool is required for understanding biological information for engineers to make appropriate decisions in choosing a construction system. In this research, a geographical information system (GIS), an entity-relationship (ER) model, a database and superobjects are used to develop a "Construction Influence Information Management System for Coastal Engineering". In this system, the species, quantity, and appearance time of all creatures within the area of the Ko-Ya Recycling Center in Hsin-Chu can be recorded.

This study is based on the ER model and database, where Delphi is used as the major development tool to establish an environmental management system of river ecology and achieve the required functions [2]. Through the results of this study, users can integrate ecological information with the system. Users can establish a relevant ecological database structure according to requirement and use ecological data from the results of the group for other programs to test the structure, function and stability of this system [3].

This system combines management information systems (MIS) and GIS interfaces, which can perform the designed functional execution. The system allows users to browse relevant data and layers, and a user can edit the layer according to requirement, as well as add, modify and view relevant data.

The referred index can be stored and queried from the system to achieve a better construction system. Through the help of this system, all biological information and the listed index for the Ko-Ya Recycling Center can be recorded so the designer can query this data to exactly control the related ecological information around the project base [4]. Engineers can evaluate the restoration of the creatures to examine the effects of the project. This evaluation data can be used to adjust the design index for future projects. We can then effectively protect the earth's resources and make the best use of our natural resources.
