Lake regions face a tradeoff between water environmental conservation and social development. Although lake conservation projects along with eco-compensation policies are considered the solutions to this problem, it is often controversial and unsustainable. Therefore, it is essential to understand the key stakeholders' willingness to participate in lake conservation projects under the different compensation schemes. In this work, we conducted a choice experiment to estimate fishermen's willingness and preference for the returning fishponds to lake (RFTL) project in the Nansi Lake Nature Reserve (NLNR). Socioeconomic, perception and spatial factors are employed to analyze the preference heterogeneity of fishermen. We employed conditional logit, mixed logit and latent class models to estimates the parameters of factor variables considering the heterogeneous preferences and choice randomness across respondents. The results indicate that on average, fishermen are unwilling to change the status quo and are most concerned about the subsidy amount and contract duration in compensation contracts. However, there is obvious spatial heterogeneity in fishermen's choice preference, mainly manifested in their habitation distance to a town and fishpond location in different zones of the NLNR. Specifically, perceptions of supply and demand for water yield and water quality services significantly influence fishermen's choice, but they have opposite effects. Moreover, we estimated marginal willingness to accept (MWTA) of attributes in compensation contract and measured compensating surplus (CS) to compare different eco-compensation policy scenarios. Our results contribute to designing targeted payment policies, and promote the effective implementation of lake conservation projects and regional sustainable development.
湖区在水环境保护和社会发展之间面临着权衡取舍。尽管沿湖保护项目和生态补偿政策被认为是解决这一问题的方案，但这些方案往往存在争议且不可持续。因此，了解关键利益相关者在不同补偿方案下参与湖泊保护项目的意愿至关重要。在这项工作中，我们进行了一项选择实验，以估计渔民对南四湖自然保护区（NLNR）回湖养殖项目（RFTL）的意愿和偏好。我们利用社会经济、感知和空间因素来分析渔民的偏好异质性。我们采用条件逻辑回归、混合逻辑回归和潜在类别模型来估计因素变量的参数，考虑了受访者之间的异质偏好和选择随机性。结果表明，平均而言，渔民不愿意改变现状，最关心补偿合同中的补贴金额和合同期限。然而，渔民的选择偏好存在明显的空间异质性，主要表现在他们与城镇的居住距离和 NLNR 不同区域的鱼塘位置上。具体而言，对供水量和水质服务的供求感知显著影响渔民的选择，但它们的影响方向相反。此外，我们估计了补偿合同中属性的边际意愿支付（MWTA），并测量了补偿盈余（CS），以比较不同的生态补偿政策情景。我们的研究结果有助于设计有针对性的支付政策，促进湖泊保护项目的有效实施和区域可持续发展。
