摘要:

吐鲁番-哈密地区(吐哈地区)作为丝绸之路经济带的关键区域,绿洲变化对维持生态平衡和经济发展具有重要价值。基于1980—2020年吐哈地区的土地利用和社会经济数据,利用ArcGIS重分类进行绿洲提取,通过趋势分析、重心迁移及地理探测器等方法,深入探讨了该区域绿洲的时空变化特征及其影响因素。结果表明:(1) 近40 a期间,吐哈地区绿洲扩张的总面积共达1651.47 km2,1980—2000年绿洲扩张速度平稳缓慢扩张222.50 km2,2000—2010年绿洲呈剧烈波动性扩张440.71 km2,2010—2020年绿洲迅速扩张988.26 km2。(2) 吐鲁番市绿洲的变化显著区域主要集中在高昌区艾丁湖乡和阿拉沟河流域,哈密市的绿洲扩张区域集中在伊州区城镇周边和巴里坤哈萨克自治县巴里坤山用于农业生产的绿洲。(3) 吐哈地区的绿洲重心存在明显空间迁移特征,由吐鲁番市鄯善县逐步向哈密市伊州区转移,且各区域绿洲重心迁移轨迹表现出显著空间异质性。(4) 雪水当量与社会经济因素共同影响吐哈地区的绿洲变化,其中雪水当量是主要因素,哈密市的绿洲变化更依赖GDP等社会经济指标,吐鲁番市则主要受雪水当量和水资源总量等自然因素影响。研究结果可为吐哈地区未来的可持续发展战略及水资源重点研究区域提供科学依据和参考。

Abstract:

As a strategic hub along the Silk Road Economic Belt, the Turpan-Hami region plays a vital role in maintaining ecological balance and supporting economic development through its evolving oasis systems. This study examines the spatiotemporal characteristics of oasis variations and their driving factors in the Turpan-Hami region, using land use datasets, socioeconomic indicators, and ArcGIS-based oasis delineation techniques. The main findings are as follows: (1) Over four decades, total oasis expansion reached 1651.47 km2, with phased development patterns: Moderate growth of 222.50 km2 during 1980—2000, expansion of 440.71 km2 with marked fluctuations during 2000—2010, followed by accelerated stabilization at 988.26 km2 during 2010—2020. (2) Spatially, the most significant transformations occurred in Aiding Lake Township of Gaochang District and the Alagou River Basin in Turpan City, while in Hami City expansion concentrated on the urban fringe of Yizhou District and the Tianshan Mountain-fed agricultural oases in Barkol Kazakh Autonomous County. (3) The oasis centroid shifted notably, gradually migrating from Shanshan County of Turpan to Yizhou District of Hami, with distinct spatial heterogeneity in trajectory patterns across subregions. (4) Snow water equivalent and socioeconomic factors jointly influenced oasis dynamics, with snow water equivalent identified as the dominant driver. Oasis evolution in Hami showed stronger correlations with socioeconomic indicators (e.g., GDP), whereas in Turpan natural determinants, including snow water equivalent and total water availability, played the primary role. These findings provide an empirical basis for developing sustainable strategies and optimizing water resource governance in this ecologically fragile region.
