青海湖流域を対象に、PLUSモデルとInVESTモデルを用いて2000～2020年のPLESパターンと炭素貯留量の変化を分析し、2035年の4シナリオ（自然発展、生態保護、経済発展、持続可能）をシミュレーションした。生態空間が炭素貯留に最も貢献し、持続可能シナリオが最もバランスの取れた増加を示した。
English
Using PLUS and InVEST models, this study analyzes PLES pattern evolution and carbon stock changes from 2000-2020 in Qinghai Lake Basin, and simulates 2035 under four scenarios. Ecological space is the main carbon contributor; the sustainable development scenario achieves the best balance with a 4.87×10^6 Mg increase in carbon stock.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
青海湖流域は中国の脆弱な高標高地域であり、日本には直接的な関連は薄いが、生態系炭素ストックのシナリオ分析手法は、日本の国土計画や森林炭素吸収源評価に応用可能。
In the global GX context
This study provides a methodology for assessing land-use trade-offs on carbon storage in ecologically sensitive regions. While specific to China's Qinghai-Tibet Plateau, the multi-scenario modeling approach is globally transferable for spatial planning and ecosystem service valuation.

📄 Abstract（原文）
The Qinghai Lake Basin, a typical ecologically vulnerable, high-altitude, cold region, requires coordinated ecosystem conservation and socio-economic development to achieve territorial sustainability. Based on the Production–Living–Ecological Space (PLES) framework, this study used land use data from five periods between 2000 and 2020 and integrated the PLUS and InVEST models to examine and simulate the evolution of PLES patterns and carbon stock under four scenarios—natural development, ecological protection, economic development, and sustainable development—in 2035. The results show that the PLES pattern in the Qinghai Lake Basin remained generally stable from 2000 to 2020, with ecological space dominating the landscape, while production and living spaces expanded slowly. Carbon stock increased from 214.73 × 106 Mg to 264.70 × 106 Mg, representing a growth rate of 23.27%. Its spatial distribution is highly consistent with the PLES pattern, with ecological space being the main contributor. By 2035, carbon stock is projected to slightly increase under the natural development scenario; under the ecological protection scenario, the expansion of ecological space leads to an increase in carbon stock; it decreases under the economic development scenario due to the encroachment of ecological space by construction land expansion; and under the sustainable development scenario, which balances economic development and ecological protection, carbon stock increases by 4.87 × 106 Mg, achieving the best overall performance. Therefore, it is essential to properly coordinate the relationships among PLES components to achieve synergistic enhancement of ecosystem services and regional sustainable development. The findings provide methodological references and decision support for sustainable development in the Qinghai–Tibet Plateau and other ecologically vulnerable regions.
