青藏高原草地生产-生态功能分区图（2000-2020）

青藏高原草地生产-生态功能分区图（2000-2020）通过在 ArcGIS 中对草地生态系统生态功能重要性和生产功能重要性等级图进行条件叠加分析得出。草地生态系统生态功能重要性以及生产功能重要性等级图空间分辨率为1km，由2000-2020年生态功能和生产功能指数的平均值分级得到。在ArcGIS中对青藏高原草地生态系统生态功能重要性以及生产功能重要性等级图进行逐一条件叠加：当保护等级显著高于发展等级的区域时（等级差超过1个级别时，即生态>生产），划定为共牧利用草地；当发展等级高于保护等级时或当保护等级和发展等级均为中等重要时，划定为传统放牧草地；而当生产功能重要性和生态保护重要性均较为一般（即说明该地生产功能较为一般且保护等级相对较弱）、或二者均为极其重要（即说明该地生产功能较强且保护等级也极其重要）时，划定为高效牧业草地。除此之外，根据张庭康等获得栽培草地分布区，并将自然保护区都列为高度保护草地，从而得到青藏高原的生产-生态功能分区图。该数据明确了不同区域的保护与发展导向，可辅助草地资源规划与生态保护决策，未来结合动态监测数据能为青藏高原可持续发展提供更精准的支撑。

The Grassland Production-Ecological Function Zoning Map of the Qinghai-Tibet Plateau (2000–2020) was generated via conditional overlay analysis of the grassland ecosystem’s ecological function importance grade map and production function importance grade map in ArcGIS. The spatial resolution of both grade maps is 1 km, which was derived by grading the average values of the ecological function and production function indices across the 2000–2020 period.

Subsequent sequential conditional overlay analysis was performed on these two grade maps in ArcGIS, with zoning criteria defined as follows:
- Areas where the conservation grade is significantly higher than the development grade (with a grade difference exceeding 1 level, i.e., ecological importance > production importance) are categorized as co-grazing grasslands;
- Areas where the development grade exceeds the conservation grade, or where both the conservation and development grades are moderately important, are classified as traditional grazing grasslands;
- Areas where both production function importance and ecological conservation importance are relatively minor (indicating general production function and relatively weak conservation grade), or both are extremely important (indicating strong production function and highly critical conservation grade), are designated as high-efficiency grazing grasslands.

Additionally, drawing on the cultivated grassland distribution areas mapped by Zhang Tingkang et al., and classifying all nature reserves as highly protected grasslands, the final production-ecological function zoning map of the Qinghai-Tibet Plateau was compiled. This dataset clarifies the conservation and development orientations of distinct regional areas, supports grassland resource planning and ecological protection decision-making, and will offer more precise support for the sustainable development of the Qinghai-Tibet Plateau when integrated with dynamic monitoring data in future applications.
