由於台灣地區的水體環境大多未能達到河川水質分類標準，因此如何從各種河川污染整治技術中，探討出最佳的應用組合方式為目前最重要的課題。其中河川自然淨化處理系統(NTS)衍生價值十分多元，若能將此系統納入水資訊規劃時之參考，將有助於整體水環境之整合。本研究為利用地理資訊系統(GIS)作為各類資料之主要處理分析工具，並配合功能估算表與技術關聯資料庫，尋求河川自淨系統可用之施作場然淨化生態保育與淨化場址功能評估之參考。 Presently, the water body in Taiwan does not reach the standards of the water body classification. F For this reason, we have to choose the best collocation from the river restoration technology. The NTS (natural treatment system) is a good approach to improve water quality. It can not only improver Water quality but also bring a lot of benefit to our environment and society. This paper used the environmental GIS (geographic information system) to build the technical databank and functional estimation of the NTS. And this research can also help the policy-maker Select the fitting site for the NTS by operation deciding system to as the reference for policy.
