Grassland Ecosystem Health Assessment in Eastern Kunlun Mountains, 1990-2020

A supplementary document analyzing grassland ecosystem health in the Eastern Kunlun Mountains from 1990 to 2020. The study uses a Pressure-State-Response model and geographical detector methods to assess spatio-temporal dynamics and identify driving factors. The dataset was authored by Yongxiao Zhu and is available under a CC-BY-4.0 license.

Use Cases

• Modeling grassland ecosystem health trends based on the described Pressure-State-Response framework.
• Identifying spatial drivers of ecosystem change based on factors like land use area ratio and grazing intensity.
• Analyzing temporal shifts in obstacle factors for ecosystem health, such as vegetation degradation (NDVI) and climatic drought (SPEI).

Strengths

• Provides a 30-year temporal analysis from 1990 to 2020.
• Includes specific quantitative results, such as an average health index of 0.2231 and a net improvement rate of +7.35%.
• Identifies key driving factors with quantified influence (e.g., land use area ratio Q=0.247).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file is a DOCX document (642.4 KB), which may require extraction or conversion for computational analysis.
