英文摘要The current suitability evaluation methods for land resources human activity in China suffer from theoretical deficiencies related to fundamental data accuracy, elevation and slope classification, and suitability class judgment. Empirical application of these methods is also hindered by excessive evaluation indicators, data acquisition difficulties, and limited applicability to high altitude regions. To address these issues, this paper proposes a technical evaluation framework for the Qinghai-Tibet Plateau (QTP) that employs selected key parameters varying with elevation and slope to establish grid-scale evaluation models for construction land suitability (CLS) and arable land suitability (ALS). A generalized algorithm is then proposed for key parameters such as air density, air temperature, slope suitability for construction, and soil erosion resistance of sloping arable land. Empirical research is conducted using Milin County in southeast Tibet as a case study, with interval measurements of 100 m in elevation and 1 degrees in slope. The evaluation model is tested using grid accuracies of 30 m, 50 m, 100 m, 250 m, 500 m, and 1000 m. The results reveal that: Firstly, the CLS and ALS can be categorized into five classes: highly suitable, suitable, moderately suitable, marginally suitable, and unsuitable, with varying area ratios under different grid accuracies. Secondly, existing construction lands in Milin County are mainly distributed in suitable, highly suitable, and moderately suitable CLS classes, accounting for over 94% of the total area studied under different grid accuracies. While arable land is mainly distributed in suitable, highly suitable, and moderately suitable ALS classes, accounting for over 96%. Thirdly, the empirical research in Milin County indicates that the evaluation method, quantitative model, and parameters algorithm for evaluating human activity suitability of land resources on the QTP are feasible and applicable, with a recommended grid accuracy within 100 m and a maximum of 250 m. Fourthly, the paper establishes a correspondence between land suitability (including construction land and arable land) and topographic factors (elevation and slope) that can be applied to the QTP. Finally, some professional defects in the evaluation methods of available land resources in Major Function Zoning and "Double Evaluations" of Territorial Spatial Planning in China when applied to the QTP are identified.
