Revealing public preferences regarding the ecological restoration of a river basin and evaluating the associated social benefits provide important references for the development of related policies. Taking the Shiyang River Basin as an example, this study quantified and analyzed the difference in public preferences regarding the ecological restoration of the river basin by the choice experiments method and the random parameters logit (RPL) model. It also evaluated the social benefits of river basin ecological restoration. The results showed that (1) The residents all hoped to improve the ecological environment of the Shiyang River Basin and were willing to bear certain restoration costs. (2) There were significant differences in public preferences for ecological restoration of the river basin. These differences existed between the upper, middle, and lower reaches of the river and between urban and rural residents. (3) The average annual cost of ecological restoration that the basin residents were willing to pay was between 505.833 ∼ 948.571 RMB yuan, and the total annual benefits of ecological restoration were 381.2 million RMB yuan. Based on these conclusions, the following recommendations were made. First, future ecological and environmental policies should be further combined with public preferences; and even cross-regional ecological compensation can be introduced to balance the interests of different social groups, to win public support. Second, increased water-saving technology in industries and agriculture, residents’ awareness of water conservation, and the management of water pollution measures should be promoted in order to improve the ecological environment of the river basin. Third, the budget for the ecological restoration of the Shiyang River Basin should be 381.2 million yuan per year. Costs should be controlled while meeting the restoration goals.

流域生态恢复的公众偏好分析和社会效益评价：石羊河选择试验的应用

揭示有关流域生态修复的公众偏好并评估相关的社会效益，为制定相关政策提供了重要参考。以石羊河流域为例，通过选择实验方法和随机参数logit（RPL）模型对流域生态恢复过程中公众偏好的差异进行了量化和分析。还评估了流域生态恢复的社会效益。结果表明：（1）居民都希望改善石羊河流域的生态环境，并愿意承担一定的恢复费用。（2）流域生态恢复的公众偏好存在显着差异。这些差异存在于上，中，以及河流下游以及城乡居民之间。（3）流域居民愿意支付的生态恢复年均费用在505.833〜948.571元之间，生态恢复年总收益为38120万元。基于这些结论，提出了以下建议。首先，未来的生态和环境政策应与公众偏好进一步结合；甚至可以实行跨区域生态补偿，以平衡不同社会群体的利益，赢得公众的支持。其次，应提高工农业节水技术水平，提高居民的节水意识，加强水污染措施的管理，以改善流域的生态环境。第三，石羊河流域的生态恢复预算为每年3.812亿元。在满足恢复目标的同时，应控制成本。
