In recent years, Pingtung County has been promoting the ecological engineering method to purify water. Until now, several researchful plans were finished, the ecological engineering method industry of the Wulo River water quality improving project was completed and put into operation, and Linluo Township multi-purpose ecological park is to be started this year. Additionally, Pingtung County Environmental Protection Bureau is inspecting the natural water purifying sites available for constructed wetlands. How to assess the most proper priority sites is one of the main tasks in 2005. The priority site shall be decided by listing all candidates first and inspecting them on the spot. There were twenty four sites undergone on-the-spot inspection in this year, among which several sites were chosen according to eight assessing factors. Finally, the seminar was held to decide the order of importance for the constructed wetland construction time in consideration of all potential conditions by the assessing methods of experts and scholars.
