Fang Li-hsing proposes some temporary measures to improve river ecologies here. Since Taiwan's rivers all flow individually to the sea, pollution in one doesn't affect the others. Hence sections of rivers could be closed off for three years to revive their ecologies.
當下若要針對被破壞的河川進行復育，方力行提出建議：台灣的河川都是各自獨流入海，各條河川的汙染和破壞程度互不相關，如果在棲地還沒破壞前把一段河川對外封閉，則三年之後，還是可以恢復河川生態。
