多功能人工湖永續經營研究

Abstract

「人工湖」目前在水源運用上已逐漸被接受並推廣，就廣義而言，除了目前正推動中如高屏大湖(吉洋人工湖)一類之大型人工湖外，傳統上之滯洪池及生態池等具有儲水能力的人為設施，就其本體上而言亦可視為人工湖的一種。惟上述之大型人工湖，滯洪或生態池等之設置在以前皆僅以滿足單一需求為考量。 本計畫目的在完成兼具水源運用、生態景觀與滯洪功能的多功能人工湖之整體系統規劃設計方法與原則，並藉由一模擬設計案例展示其功能與效益。此多功能人工湖可為新型態水資源永續經營的一環，以平原區的中小型人工湖為例，其水源可為當地地表逕流，或是外來人工渠道引入，視其在水源運用及生態維護之需求而定，若經適當設計，其將可維持合適的水量和水質環境，來提供生態與景觀維護的需求，而提昇當地的生態及景觀的品質，若能推廣此種中小型多功能人工湖，則對整個區域的生態品質應能有實質的提昇。

Traditionally, we establish one facilities for one function, like reservoir and detention pond. The aim of the plan is to integrate multi-objection to one facilities. Lake system should be designed to meet the objection of the use of water, flood reduction ,and biological diversity. This plan is to provide a basic description of the function and behavior of lake system. This is to find some rule for design and to highlight the issues for maintain. It proves that lake system arise quantity and quality of water and is a good habitat for creatures.
