  "abstract": "目的为科学评估极端干旱背景下南疆地区防风固沙服务时空演变及其生态经济价值，精准掌握区域防护成效并优化防沙治沙布局。方法基于2000—2024年多源遥感与气象观测数据，利用本地化修正风蚀方程（RWEQ）定量估算防风固沙量及保有率；结合替代成本与机会成本法系统核算多维经济价值，并采用参数最优地理探测器（OPGD）揭示防风固沙空间分异的驱动因素及其协同效应。结果研究期内南疆地区植被覆盖整体呈极显著改善趋势，驱动防风固沙总量与保有率呈先降后升的“V”形演变特征，空间呈现“边缘绿洲高、腹地沙漠低”的圈层格局。多年平均防风固沙总价值达1 640.84亿元，其中保持土壤肥力价值占绝对主导地位（贡献率达94.05%）。土地利用类型和NDVI是主导防风固沙空间格局的核心因子，且与气温、降水等气候要素存在强烈的交互增强效应。区域防风固沙峰值集中于NDVI为0.16~0.23的草地、年降水量178~329 mm的山前过渡带及距河流4.4~10.0 km的河岸生态廊道。结论持续推进的生态工程有效提升南疆地区防风固沙效能并驱动生态资产稳步增值，其核心经济意义在于避免表层稀缺养分随风沙大量流失，保护干旱区脆弱的表层土壤；复合环境因子的协同作用决定保障绿洲安全的最适生态阈值。研究结果可为极端干旱区生态资产量化评估与关键防线空间配置提供参考。",
