文摘[目的]分析新疆维吾尔自治区1986—2025年的盐碱地治理政策演变特征,以期为该区后续盐碱地治理利用工作提供科学指导。[方法]基于政策内容演变与关键节点判别法,对1986年至今公开发布的160份新疆盐碱地治理政策进行阶段划分,通过ROST Content Mining System V6.0软件的词频分析和社会语义网络分析工具,对各阶段政策进行文本挖掘与量化分析。[结果]①新疆盐碱地治理政策历经起步规划(1986—2013年)、专项整治(2014—2021年)和综合利用(2022—2025年)3阶段。②各阶段特征鲜明,起步规划阶段以土壤改良和系统性规划为核心;专项整治阶段注重耕地质量提升与生态环境保护;综合利用阶段聚焦盐碱地综合利用与高标准农田建设。③随着时间的推移,政策向全面化、精细化方向发展,治理目标转向盐碱地多元利用与可持续发展,治理过程注重与生态环境保护的平衡协调,治理框架日趋完善,治理措施逐渐多样。[结论]基于政策内容的阶段划分与文本挖掘方法可以系统揭示新疆盐碱地治理政策的发展与演变特征,具有良好的适用性与可操作性。
