中文摘要：

土地利用功能的概念是一种重要的可持续发展评估工具。为了探索政策制定者与农户在土地利用功能认知上的差异以及不同土地利用类型在供给不同功能能力上的差异,本研究使用参与式评估方法以固原市作为案例开展了土地利用功能评估。研究方法包括4个部分：文献综述与实地调研、土地利用功能背景分析、土地利用功能重要性和权重分析、结果可视化和进一步讨论。结果显示,政策制定者对区域发展问题以及土地利用功能认知能力较强,而农户对影响生计生活的当地问题认知水平较高。基于决策制定者认知的评估显示,土地利用的环境功能的重要程度较经济和社会功高;基于农户认知的评估,经济和社会功能比环境功能更加重要。但是,基于决策制定者和农户的评估均显示固原市土地利用的环境功能值最高,经济功能值最低。参与式的评价方法能够帮助我们了解土地利用与土地利用功能的关系,并有益于利益相关者提高土地利用决策和管理能力,为区域可持续发展做出贡献。

英文摘要：

The land use function （LUF） concept is a useful tool in assessing sustainable development. With the goal of exploring the conceptive difference of policy makers and local farmer on LUFs and understanding the capacity of different land use types to provide LUFs, we used a participatory method to assess LUFs in Guyuan, which included four phases： literature review and field surveys; specification of the LUF context; ranking of priorities and weighting of LUFs; and visualization and discussion of the results. It was found that policy makers perceived regional prob- lems and critical LUFs well, whereas farmers had a clearer perception of local issues that affect their livelihood. For policy makers, environmental functions had a higher priority than economic and social functions; in contrast, farmers prioritized economic and social functions. However, based on the perception of both groups, the result was the same whereby environmental functions had the highest LUF value and economic functions had the lowest. Participatory assessment methods enhanced our understanding of causal linkages between land use and LUFs, and may help stakeholders improve future land use decisions and management for regional sustainable development.
