摘要:

快速城市化引起的城市空间扩张会改变生态系统结构,削弱生境质量,进而影响可持续发展。探讨城市扩张对生境质量的影响,有助于实现土地利用的合理分配,并为生态系统服务的恢复与重建提供支持。以中国新疆天山北坡经济带为研究区,基于共享社会经济路径与土地利用情景动态-城市模型,预测了2024—2050年不同路径下未来城市扩张的情景,并评估了2000—2050年天山北坡经济带生境质量的时空格局。结果表明:(1) 2000—2023年天山北坡经济带城市用地迅速扩张,从551.72 km2扩张至1756.11 km2,扩张趋势为54.70 km2·a-1,2023—2050年在化石燃料路径下,天山北坡经济带的城市用地扩张最显著;在区域竞争路径下,其扩张最不明显。天山北坡经济带的城市用地面积将持续扩张至3176.27~3859.20 km2,扩张趋势为244.03~369.38 km2·a-1。(2) 2000—2023年天山北坡经济带生境质量从0.551下降至0.520,损失率为5.574%;2023—2050年天山北坡经济带的生境质量将持续降低,预计损失0.57×10-2~0.82×10-2,损失率为1.10%~1.58%。(3) 城市用地侵占草地是导致天山北坡经济带生境质量损失的主要原因。在未来的城市规划和管理中,天山北坡经济带应更加注重恢复生态用地,以确保区域的可持续发展。

Abstract:

Rapid urbanization and the attendant spatial expansion of urban regions can alter the structure of ecosystems, degrade habitat quality, and thereby impact sustainable development. Investigating the effects of urban expansion on habitat quality is crucial for the rational allocation of land use and supporting the restoration and reconstruction of ecosystems. This study focuses on the northern Tianshan Mountain economic zone (NTMEZ) in Xinjiang, China, where future urban expansion scenarios from 2024 to 2050 under different socioeconomic pathways are predicted using the Land Use Scenario Dynamic-Urban (LUSD-urban) model. The spatiotemporal changes in habitat quality from 2000 to 2050 in the region are also assessed. The results show that: (1) Between 2000 and 2023, urban land in the NTMEZ rapidly expanded from 551.72 km2 to 1756.11 km2, with an annual expansion rate of 54.70 km2. From 2023 to 2050, under the fossil fuel pathway, urban land expansion is expected to be most significant, whereas under the regional competition pathway, expansion is expected to be least pronounced. The area of urban land is expected to further expand to between 3176.27 km2 and 3859.20 km2, with an annual expansion rate ranging from 244.03 km2 to 369.38 km2. (2) From 2000 to 2023, habitat quality in the NTMEZ declined from 0.551 to 0.520, representing a loss rate of 5.574%. From 2023 to 2050, habitat quality is expected to continue to decrease, with an anticipated loss of 0.57×10-2‒0.82×10-2, corresponding to a loss rate of 1.10%~1.58%. (3) The main driver of habitat quality loss is the encroachment of urban land on grasslands. In future urban planning and management, greater emphasis should be placed on the restoration of ecological land in the NTMEZ to ensure the region’s sustainable development.
