哈尼梯田经营管理模式作用机制与效益评估OA

To comprehensively explore the underlying mechanisms and implementation outcomes of the Hani Terraces operation and management model,this study takes the Hani Terraces Heritage Area as a case study.Through field surveys,it analyzes its operation and management model and systematically reveals its functional mechanisms based on the Social-Ecological System(SES)framework.Furthermore,by integrating the InVEST model with the market price method,this study quantifies the soil and water conservation benefits and food production values across different land-use types,thereby evaluating the comprehensive effectiveness of the management model.The results indicate that:(1)The operation and management model of the Hani Terraces is an integrated four-component management system that is built upon the"four-element isomorphic"landscape structure,blending the traditional ecological wisdom of the Hani ethnic group with modern governance strategies.It centers around four key subsystems:forests,terraces,villages,and water systems.(2)Co-driven by local traditional knowledge and modern management,smallholders have developed a set of coordinated and orderly action situations in terms of resource management(forest and water resources)and field practices(terrace cultivation and maintenance).Through ecological maintenance,optimized resource allocation,and efficient utilization,these action situations effectively achieve the dual goals of soil and water conservation and livelihood security.(3)The comprehensive soil and water conservation benefits in the Hani Terraces Heritage Area reach 503 million CNY.Among different land-use types,paddy fields,benefiting from the effective management model,demonstrate significantly superior soil conservation capacity and grain output per unit area,yielding the highest comprehensive benefit of 41 000 CNY/ha.These findings provide a theoretical basis for the sustainable conservation and development of the Hani Terraces,while also offering a valuable reference for the research and practices of similar mountainous agricultural systems globally.
