Abstract： Marine ranching，as a refined marine aquaculture method，not only eficiently produces high-quality economic aquatic products but also objectively protects and optimizes the service functions of marine ecosystems. Accurately assessing the ecological value of marine ranching isof great significance for promoting its industrial ecological development.In this paper，the ecological valueof marine ranching is divided into four attibutes：expanding biological habitat area，conserving non-economic biological resources，improving water clarity， and enhancing ofshore ecological landscape function.By using the choice experiment method，a mixed Logit model and a latent class model areconstructed to empirically analyze the public's willingness to pay（WTP） for each ecological atribute of Zhoushan'smarine ranching and its heterogeneity，and further estimate the total ecological value of Zhoushan’s marine ranching. The research results indicate that：（1） Descriptive analysis of the sample shows that respondents generally have a high awareness of the ecological value of marine ranching， providinga basis for them to accurately express their WTP.（2）The results of the mixed Logit model analysis reveal that the marginal values of biological habitat area，non-economic biological resources，water clarity，and offshoreecologicallandscape function are70.73yuan/household/year，69.29 yuan/household/year，81.79 yuan/ household/year，and 77.27 yuan/household/year，respectively.（3）The results of the latent class model analysis indicate thatthereare significantdiferences in WTPand the degree of importanceatached toecological functions among diferent groups.（4）Ifthe ecological atributesof Zhoushan’s marine ranching are improved to theiroptimal levels，the annual WTPof respondents is 1 O70.55 yuan/household，and the total ecological value of Zhoushan's marine ranching is estimated to be 376 million yuan.The research results can provide important references for policy formulation and scientific management of the industrial ecological development of Zhoushan's marine ranching.

海洋牧场是基于海洋生态系统原理，在特定海域，通过人工鱼礁、增殖放流等措施，构建或修复海洋生物繁殖、生长、索饵或避敌所需的场所，以增殖养护渔业资源，改善海域生态环境，实现渔业资源可持续利用的渔业模式[1]。（剩余22198字）
