摘要:

新疆额尔齐斯河流域“生产-生活-生态”(“三生”)空间规划调控研究具有重要理论与实践价值。通过构建空间格网与行政区双尺度评价指标体系,揭示2000—2023年额尔齐斯河流域“三生”用地时空演变规律,诊断“三生”空间耦合协调度,并基于FLUS模型提出其空间优化调控路径。结果表明:(1)2000—2023年额尔齐斯河流域生产与生活空间分别扩张1199 km2和94 km2,生态空间缩减1319 km2,农业生产空间侵占草地、林地生态空间和城镇生活空间扩张导致生态退化。(2)生产空间高适宜区集中于城镇周边,低适宜区受限于戈壁沙地等未利用地;生活空间适宜性随城镇化提升,但未利用地的适宜性仍较低;生态空间呈现“山区优化、平原退化”的二元特征。(3)2000—2023年“三生”空间轻微失调格网数出现增加,主要分布在富蕴县和吉木乃县。濒临失调地区格网数出现减少,主要分布在布尔津县和哈巴河县。基本协调和良好协调地区格网数出现了大幅增加,主要分布在哈巴河县、阿勒泰市、福海县和北屯市。(4)额尔齐斯河流域国土空间功能提升应该在保证粮食产量的基础上以生态保护为导向,把部分生态适宜而生产不适宜的区域退耕还草,提升区域生态系统的整体服务功能。

Abstract:

The spatial planning and regulation of “production-living-ecological” spaces in the Irtysh River Basin of Xinjiang, China, have significant theoretical and practical value. This study establishes a multi-scale evaluation index system integrating spatial grids and administrative units to reveal the spatiotemporal evolution patterns of “production-living-ecological” land use from 2000 to 2023. The coupling coordination degree of these spaces is further diagnosed, and optimization pathways are proposed based on the future land use simulation model. The main findings are as follows: (1) From 2000 to 2023, production and living spaces of Irtysh River Basin expanded by 1199 km2 and 94 km2, respectively, whereas ecological space contracted by 1319 km2. This ecological degradation mainly resulted from agricultural expansion into grassland and forest ecological spaces, as well as urban sprawl. (2) High-suitability production areas are concentrated around urban zones, while low suitability areas are constrained by unused lands such as gobi deserts. The suitability of living spaces improved with urbanization, although unused lands continue to exhibit low suitability. Ecological spaces display a “mountain optimization-plain degradation” pattern. (3) From 2000 to 2023, the number of grids with slight imbalances in “production-living-ecological” coordination increased, mainly in Fuyun and Jeminai counties, whereas grids with near imbalances decreased, primarily in Burqin and Habahe counties. In contrast, the number of grids achieving basic or good coordination increased markedly, particularly in Habahe County, Altay City, Fuhai County, and Beitun City. (4) Improvement of territorial space functionsin the Irtysh River Basin should prioritize ecological conservation while ensuring food security, with targeted conversion of farmland to grassland in ecologically suitable but production-constrained areas to enhance regional ecosystem services.
