In the study, research aims at setting up a suitable framework to assess the farmland wetland by introducing proper wetland evaluation technology. Here, a two-stage qualitative 'multiple value evaluation matrix' is proposed and practiced for the 'Eco-park' planning at Fubao wetland in Changhua. Those functions such as sustenance, socio-education and production are approaching to the positive evaluation. On the contrary, the impacts induced by improper restoration planning on normal function of wetland are considered as negative evaluation. There are 70 indicial elements altogether, including some critical-value elements with importance meaning to the sustainable development in wetland. They are enhanced their weigh to strengthen the unique characteristic of wetland.
