纳入公众偏好的荒漠化治理价值评估是科学制定荒漠化治理政策的重要基础。本研究以新疆荒漠化治理价值评估为例，运用选择实验法研究公众对荒漠化治理的支付意愿和偏好异质性，并结合潜在分类模型分析受访者偏好异质性的形成机理。研究发现新疆公众对于荒漠化治理存在显著的偏好异质性，受访者可分为偏好正常型、环境友好型、价格敏感型3个潜在类别。其中，偏好正常型的受访者占比最大(68.17%),显著高于环境友好型(19.86%)和价格敏感型(11.97%);偏好正常型、环境友好型受访者对荒漠化治理属性的支付意愿大于价格敏感型受访者。分析潜在类别可知，公众的社会经济特征及环境感知对其偏好具有显著影响。较高的关注程度、治理意识和较低的年龄会促使受访者更加偏好于荒漠化环境属性的治理；收入水平、关注程度、治理意识较低的受访者，更不愿意支付较高的治理费用，在进行选择时更关注治理价格属性。研究有助于为完善当前和未来的荒漠化控制和管理提供理论依据和技术支撑，增强政策或项目的合理性和可行性。

The evaluation of economic value of desertification control, which includes the consideration of public preferences, is an important basis for formulating scientifical desertification control policies. By examining the evaluation of desertification control in Xinjiang, this article employs the choice experiment method to investigate public willingness to pay and preference heterogeneity for desertification control, and introduces a latent class model to analyze the factors contributing to heterogeneous preferences among respondents. The results show that there is significant heterogeneity in preferences for desertification control among the general population of Xinjiang. Specifically, respondents can be divided into three latent class, which is named: preference-normal type, environment-friendly type, and price-sensitive type, respectively. Among them, the largest proportion of respondents(68.17%) belongs to the preference-normal type, which is significantly higher than those of the environment-friendly type(19.86%) and price-sensitive type(11.97%). The respondents categorized as preference-normal type and environment-friendly type exhibit higher willingness to pay for desertification control attributes. The results also reveal the relationship between public preferences and their socio-economic and environmental attitude characteristics. Specifically, respondents who are younger and with a higher level of concern and control consciousness tend to improve desertification control attributes, whereas respondents with a lower level of concern, control consciousness and income show a lower willingness to pay. The findings are helpful to provide theoretical basis and technical support for improving the current and future desertification control and management, which contribute to enhancing the rationality and feasibility of policies or projects.
