摘要:

祁连山地区是我国重要的生态功能区,也是我国生态环境脆弱区之一,研究祁连山地区自然-经济-社会复合生态系统韧性,以期有效治理祁连山地区生态环境问题。构建三维空间矢量模型、耦合协调模型和障碍度模型,测度2007—2021年祁连山地区复合生态系统韧性和子系统耦合协调性,揭示影响复合生态系统韧性提升的障碍因子,并借助地理信息系统技术分析复合生态系统韧性的空间演化过程。结果表明:(1) 祁连山地区复合生态系统韧性呈上升趋势,空间上呈现从东部逐渐向西部降低的趋势;自然子系统韧性呈下降趋势,空间上呈现中东部向西北部逐渐降低的趋势;经济子系统韧性呈上升趋势,且增速较快,高经济韧性集中分布于东部和北部;社会子系统韧性上升幅度不大,高社会韧性集中分布于东部。(2) 祁连山地区复合生态系统韧性耦合度提升明显,已达到高水平耦合;耦合协调度呈波动上升,已达到中级协调等级。(3) 自然子系统对复合生态系统韧性提升影响较大,来自经济子系统的指标障碍度提升明显。

Abstract:

The Qilian Mountain area is an important ecological function area and one of the most fragile ecological areas in China. Our objective is to study the natural economic-social ecosystem resilience in the Qilian Mountain area to effectively manage ecological challenges. To achieve this, we constructed a three-dimensional spatial vector model, coupling coordination model, and obstacle degree model. These models were employed to measure complex ecosystem resilience and subsystem coupling coordination in the Qilian Mountain area from 2007 to 2021. Additionally, we aimed to reveal obstacles affecting the improvement of the complex ecosystem resilience and analyze the spatial evolution process of complex ecosystem resilience using geographic information system technology. The results show the following: (1) Complex ecosystem resilience in the Qilian Mountain area is increasing, following a spatial decrease trend from the east to the west. Natural subsystem resilience is declining, with a spatial trend of decreasing from the central east to northwest. The economic subsystem resilience is increasing rapidly, with high economic resilience concentrated in the east and north. Social subsystem resilience rises modestly, with high social resilience concentrated in the eastern part of the area. (2) The complex ecosystem resilience coupling in the Qilian Mountain area has considerably improved, reaching a high-level coupling degree, and the degree of coupling coordination shows a fluctuating increase, reaching an intermediate coordination level. (3) The natural subsystem greatly impacts the improvement of complex ecosystem resilience, and the obstacle degree of the indicators from the economic subsystem exhibits a notable increase.
