本研究主要目的在探討自然淨水系統設置與社會人文因素之相關性。研究範圍為台南縣地區，對象為台南縣社區居民，調查方式是以研究者自編之問卷作為研究工具進行調查，總計回收有效樣本計382份。
本研究將社區居民對自然淨水系統設置之影響因素區分為「政策經濟」、「管理維護」、「生態保育」、「環境健康」、「教育文化」共五個構面，經統計分析後，茲將研究發現歸納如下：
1 .在政策經濟方面，多數社區居民認為設置自然淨水系統對社區發展、社區永續有影響， 於適當規劃後可以為居民創造利益，在規劃方面可與景觀休閒設施結合，希望社區能爭 取補助，亦希望政府單位推廣。但亦有多數居民認為建置自然淨水系統不如整建下水 道，因此，除整建下水道外，獲得多數社區居民認同的自然淨水系統，亦是相關決策單 位考量設置規劃的方向。
2.在管理維護方面，多數社區居民認為自然淨水系統的後續營運與管理很重要，需要專家 學者的協助指導與專責管理人員的持續維護，而操作經費的有無以及社區民眾的參與亦 影響系統的維持。但是有八成社區居民認為自然淨水系統不易維護，因此，如何導正居 民對自然淨水系統不易維護的觀念，亦是未來推廣設置時的重點。
3.在生態保育方面，多數社區居民認為自然淨水系統能作為生態遊憩場所，可達到生態保 育的效果，且有助於野生動植物的生存。因此，建構兼具污染改善、生態保護與休閒遊 憩的多弁鄖t統，將是未來參酌的方向。
4.在環境健康方面，多數社區居民對自然淨水系統改善社區污水及污染防治的效果予以肯 定，且同意於居住的社區設置自然淨水系統，但仍有多數居民擔心系統會造成蚊蟲孳生 及成為孩童危險遊戲場所等環境問題，因此，解決蚊蟲孳生與安全防範問題，應是未來 設置改善的重要考量。
5.在教育文化方面，多數社區居民認為自然淨水系統的設置，有助於提昇民眾生態保育觀 念、凝聚社區意識、且具有環境教育的弁遄A需要社區居民共同參與。因此，廣納社區 居民不同意見，讓居民參與設置規劃，取 得居民的認同，邁向永續經營將是未來共同努 力的目標。 This main purpose of research is investigating on the construction of treatment system affected by the social humane factors. The survey target is the residents of community in Tainan county, Taiwan. The investigation method is base on questionnaire which focuses on social viewpoints concering natural treatment system and the amount of the effective sample retrieved is 382. In this research, the factors might relate to the construction of natural treatment system are divided into five areas ： "policy", "management", "ecological restoration ", "public health", and "education"The detailed issues of these five areas are shown as the following: 1. Policy : Most of residents in the community felt that the construction of natural treatment system will affect the sustainable development of the community and also can benefit residents with proper plan if combined with recreation facilities in the plan. They hope the government can support and provide the budget for the project. Also think that the sewage system would be more practical than natural treatment system, so besides the sewage system, most of residents agree that the construction of natural treatment system is one of the important issues in the political decision making.
2. Management: Most of residents think that the operation and management of the natural treatment system is very important and is necessary to be complied by administrative staffs under guidance of specialized experts. Meanwhile, operating budget and participation of the local people in the community also influence the sustainable operation of the system. But 80% of the residents think that the natural treatment system has difficulty to be maintained. Therefore, setting up the proper viewpoints of public when planning the system is an important step.
3. Ecological restoration: Most of the people think the natural treatment system can be an ideal place for the ecology and would achieve ecological restoration by providing habitats for wild animals and plants. Therefore, natural treatment systment would improve the pollution due to the environmental and the ecological protection. So that the multi-functional systems will be a direction to be considered in the future.
4. Public health: Most residents aware pollution reduction will result from natural treatment system in the community where they are living in. But many of them worry about the system may cause mosquito and become the hazardous place for the children. Therefoure, public health is the one of important issues to be considered in the future.
5. Education : Most residents think the establishment of natural treatment system promotes the idea of ecological restoration, flocs the consciousness of the community, and has function of environmental education. These results need residents other communities to participate. So, collection of the various suggestions from the residents, residents participation in setting up and planning, and gain of the support of residents are goals to be worked on in order to achieve sustainable management of natural treatment system in the future.
