Wetland with rich and diverse resources is a base of the sustainable development. Along with the western of Taiwan, the overdeveloped coasts have made an impact on the ecological environment. Among these coasts, Chiku can keep on sustainable development or not based on residents' attitude. The purpose of this survey is on the diversenesses among residents in different areas on attitude toward wetland conservation, attitude toward ecological tourist development and choice for sustainable development on the wetland. The survey aims at residents who live in Chiku, especial along with the coast. From 322 copies of available questionnaire and 40 interviews with members from the public and private sectors and nonprofit organization, we apply the methods like descriptive statistics, reliability analysis, one-way ANOVA and t-test to analyze the data and find out the results: 1. For the future of wetland development in Chiku, residents think it is necessary to integrate fishing resources, emphasize wetland characteristics and rise residents' participation, then local economy can be boosted and there will be more job opportunities. 2. There is a great disparity for Chiku's future among residents with different age. Residents from 30 to 34 can accept the development plan of environment protection; comparatively, residents from 40 to 44 can accept the development plan of prospering Chiku and satisfying the life. 3. When residents get more information concerning ecological environmental conservation and take relative courses, they will face the environment positively and support the way of complying with ecological conservation. According to the result of this survey, we suggest that: 1. Under the rule of sustainable development, we need to adopt residents' opinions, boost their participation, and increase job opportunities. 2.
