高寒生态脆弱区环境本底敏感而脆弱,生活垃圾不当处理极易加剧生态系统退化风险,揭示区内农牧民生活垃圾集中处理的多主体互动机制及政策激励效果对落实生活垃圾治理、降低生态风险和提升人居品质具有重要意义。基于藏北牧区的案例,考虑高寒生态脆弱区的气候高寒、牧民定居点分散等现实约束,构建村镇基层政府和农牧民的演化博弈模型,探究区内农牧民生活垃圾处理的激励机制。结果显示:①农牧民参与是提高高寒生态脆弱区生活垃圾集中处理效率的关键,村镇基层政府的奖惩措施能够显著激励农牧民参与生活垃圾集中处理,奖惩机制中惩罚的约束作用更为显著。②村镇基层政府的宣传和设施建设措施能够显著促进农牧民参与生活垃圾集中处理,设施配置对农牧民参与行为影响的敏感度明显大于宣传教育,完善设施建设是促进生活垃圾集中处理的关键措施。③优化高寒生态脆弱区农牧民生活垃圾集中处理制度的政策导向:立足高寒生态脆弱区气候高寒、牧民定居点分散及产污特性,优化生活垃圾集中处理设施的规划建设和运行管理、加强村镇基层政府参与治理的检查评估和行政管理、完善农牧民参与治理的激励约束机制。

The conflicts in spatial planning are the main reason that restricts the sustainable development of land use in China, and it is also the main barrier to the building of “Territorial Spatial Planning System”. This study analyzes the conflicts between urban planning and land-use planning from the three dimensions of construction land, basic farmland and ecological land based on a land-use transition matrix with the central urban area of liupanshui City, Guizhou Province as a case region, and analyzes the causes of spatial planning conflicts from the perspectives of the central and local governments in terms of their preferences and interactive relationships. The main conclusions of this paper are as follows.(1) Urban planning and land-use planning have comprehensive conflicts with each other in terms of the construction land, basic farmland and ecological land, i.e. the scale of construction land in urban planning is 154% of that in land-use planning, and the scale of basic farmland in urban planning is 88.56% of that in land-use planning.(2) Central and local governments are the two main stakeholders of spatial planning,and they have different preferences for the utilization of spatial resources at prefecture-level *** central government is concerned about food security, and therefore, pays more attention to the protection of cultivated land, while the local governments focus on economic benefits and the ecological environment, and therefore, pay more attention to construction and ecological lands.(3) The urban planning system is a bottom-up design system, which determines that urban planning mainly reflects the preferences of local governments, while the land-use planning system is a top-down design system, which determines that land-use planning mainly reflects the central government’s preferences. The policy implication of this study is that in order to manage spatial planning conflicts, it is necessary to manage the conflicts of interest among stakeholder
