摘要:

自然资本可持续利用是区域高质量发展的核心议题。以青海省8市州为对象,综合运用改进的三维生态足迹模型、标准差椭圆模型及时空地理加权回归(GTWR)模型,从市州尺度定量研究了2012—2022年青海省自然资本利用的时空动态特征及其驱动因素。结果表明:(1) 2012—2022年青海省人均生态足迹由2.5 hm2·人-1增至3.0 hm2·人-1,人均生态承载力由0.6 hm2·人-1增至0.8 hm2·人-1,人均生态赤字由1.9 hm2·人-1扩大至2.5 hm2·人-1,足迹重心向西北迁移,反映资源环境压力持续增大。(2) 空间上,玉树藏族自治州、海西蒙古族藏族自治州和果洛藏族自治州生态足迹较高,西宁市最低;仅海东市处于生态盈余,且其足迹广度最高,果洛藏族自治州足迹广度最低;玉树藏族自治州和果洛藏族自治州足迹深度最高。(3) 自然资本资本流量占用率和存量流量利用比的空间差异明显且整体呈“西高东低”的空间分布特征,8市州处于轻度可持续以下状态。(4) 自然资本利用影响因素空间异质性显著,固定资产投资增速回归系数呈“北低南高”,发电量回归系数“东低西高”,需因地制宜实施差异化策略,促进生态与经济协同发展。研究结果可为青藏高寒区生态资源管理及可持续发展提供科学依据。

Abstract:

The sustainable utilization of natural capital is a core issue in regional high-quality development. This study, focusing on eight cities and prefectures in Qinghai Province of China, applied an improved three-dimensional ecological footprint model, a standard deviation ellipse model, and a geographically and temporally weighted regression model to quantitatively examine spatiotemporal dynamics and the driving factors of natural capital use from 2012 to 2022 at the prefectural level. The results indicate that (1) From 2012 to 2022, the per capita ecological footprint in Qinghai increased from 2.5 hm2·person-1 to 3.0 hm2·person-1, the per capita ecological carrying capacity rose from 0.6 hm2·person-1 to 0.8 hm2·person-1, and the per capita ecological deficit expanded from 1.9 hm2·person-1 to 2.5 hm2·person-1. The gravity center of the per capita three-dimensional ecological footprint shifted northwestward, reflecting an increasing pressure on resources and the environment from human economic activities. (2) Yushu Tibetan Autonomous Prefecture, Haixi Mongolian and Tibetan Autonomous Prefecture, and Golog Tibetan Autonomous Prefecture had larger ecological footprints, while Xining City was the lowest. Haidong City was the only region with an ecological surplus. Haidong City had the largest footprint, and Golog Tibetan Autonomous Prefecture the smallest; Yushu Tibetan Autonomous Prefecture and Golog Tibetan Autonomous Prefecture showed the greatest depth of footprint. (3) Both the natural capital flow occupancy rate and stock-flow utilization ratio exhibited a high in the west, low in the east pattern, and all eight prefectures were in a slightly unsustainable or worse state. (4) The influencing factors of natural capital use showed significant spatial heterogeneity: the regression coefficient of fixed asset investment growth rate showed a low in the north and high in the south pattern, while the regression coefficient of power generation had a low in the east and high in the west pattern. It is necessary to apply differentiated strategies that are tailored to local conditions to promote synergistic ecological and economic development. This study provides a scientific basis for the management of ecological resources and sustainable development in the Tibetan Alpine region.
