南投縣觀光人數從97年度至101年度，由100萬人左右暴增至550萬人左右，觀光人潮之暴增相對亦帶來數量龐大垃圾，為避免垃圾造成環境髒亂，且為有效的將一般廢棄物與資源垃圾進行分類，因此日月潭觀光區廣設一般垃圾桶與資源回收桶，以提升觀光客之垃圾收集與分類成效。為了解日月潭觀光區之垃圾分類成效，本研究乃於日月潭觀光區共選取3個採樣點，進行一般垃圾桶與資源回收桶之垃圾組成採樣與誤投分析。本研究之成果顯示，一般垃圾桶中會發現資源垃圾，其中一般垃圾桶中誤投之資源垃圾種類以廚餘所佔的比例最高，其次為紙類、塑膠袋等等，另在資源回收桶亦會發現一般廢棄物，如衛生紙，由此可知遊客民眾於日月潭觀光區之垃圾分類成效不佳，另日月潭觀光區一般垃圾桶中資源垃圾之誤投比例(85.8%)遠較資源回收桶中一般廢棄物之誤投(9.97%)為嚴重。為改善日月潭觀光區垃圾分類成效不佳之情形，本研究建議觀光區資源回收桶之外觀形狀顏色與垃圾投入口大小形狀應與一般垃圾桶有明顯區別，以加強民眾辨識區別資源回收桶與一般垃圾桶之差異，另亦可針對遊客進行垃圾分類宣導，以提升觀光區之垃圾分類成效。

The number of tourists visiting Nantou County increased from 1 million in 2008 to 5.5 million in 2012. The increasing number of tourists generate large amounts of garbage. To collect and sort the general and recyclable garbage produced by tourists, numerous general trash cans and recycling trash cans have been installed at the Sun Moon Lake tourist area for tourists to dispose of garbage. To understand the sorting effectiveness between general and recyclable garbage, this study focused on three locations at the Sun Moon Lake tourist area for analyzing the garbage composition of general and recycling trash cans by using manual on-site sampling. The result of this study indicated that recyclable garbage was disposed of in the general trash cans. The top three misplaced recyclable garbage in the general trash cans were food waste, paper waste, and plastic waste. In addition, general garbage, such as nonrecyclable tissue paper was found in the recyclable trash cans. The amount (85.8%) of misplaced recyclable garbage in the general trash cans was considerably larger than the amount (9.97%) of misplaced general garbage in the recycling trash cans. This indicates that the sorting between general and recyclable garbage at the Sun Moon Lake tourist area is markedly ineffective. Thus, strategies must be implemented to improve the garbage sorting effectiveness at the Sun Moon Lake tourist area.
