However, most ecological engineering focused on rivers, so paddy field and agricultural canals were less considered. Therefore, this study refers to the rural environment preparing in Japan and intends to find the bottleneck of the paddy field and the ecological environment around channel in Taiwan, so as to be a reference for improving and restoring the ecological environment of paddy field. In this study, an experimental paddy field was set up in Yuan-Li Township, Miao-Li county. In order to make sure of the continuity of agricultural canals and paddy fields, this study firstly improved the ecological corridor and then utilized the Misgurnus anguillicaudatus to move back and forth in the paddy field and canals, proving the effect of simple fish ladder in paddy field and technique of ladder-type stone-piling in the pool. In addition, the farmers often strew tea seed meal during transplantation of rice seedlings in the paddy field, to reduce the harm caused by Pomacea canaliculata. However, tea seed meal would endanger the creatures in the paddy field. Therefore, this study intended utilize Vanillin-sulfuric acid and Misgurnus anguillicaudatus to find out the duration of harm caused by tea seed meal and the solution to reduce the har,. From the result of the research, we can know that it is very important to understand the situation of the target area by various surveys. Meanwhile, it is also found that the concrete agricultural canal and its vertical unification are the main reason for the lowered ecological quality. The creatures in the paddy field can improve discrepancy between the cross-section and vertical section of the ecological corridor through the simple fish ladder in paddy field and the technique of ladder-type stone piling in the pool. After the ecological corridor was improved, we can see creatures, such as fish and shrimps and so one, moving in and out in the paddy field. Thus, it is suggested to keep observing the life history of all creatures in the paddy field, so it can be a reference for ecological restoration. Besides, it is suggested to block the outlet of the farmland and strew the tea seed meal after transplanting rice seedlings. Moreover, it is also recommended to irrigate the paddy field after two days in summer and three days in winter. It’s not recommended to drain water, so as to reduce the harm to creatures. Besides, the high water temperature in summer also has negative influence over the paddy field and creatures. 陳榮松 2008 學位論文 ; thesis 151 zh-TW
