| 摘要: |
| 【目的】深入剖析喀斯特地区水资源利用问题，从自然资源供应与需求关系辨析水资源利用状况，以期为喀斯特地区水资源高效开发利用与可持续发展提供科学依据和有益参考。【方法】生态足迹模型是生态经济学中测量人类社会资源消耗的经典方法，基于能量流的能值生态足迹模型是该领域研究的最新成果。本研究选取贵州高原典型喀斯特区域—南明河流域为研究对象，基于2010—2020年南明河流域的用水量、供水量等数据，运用能值水资源生态足迹模型系统地分析了南明河流域2010—2020年的水生态足迹、水生态承载力、水生态赤字和生态压力等变化情况。【结果】①2010—2020年，南明河流域水资源能值生态足迹年均值为1.080 hm2/人，水资源能值生态承载力年均值为0.562 hm2/人，水资源生态赤字明显，但整体呈逐年下降趋势；②南明河流域水资源生态压力指数年均值达2.004，处于亚安全状态，生态系统承受压力在较安全范围；③2010—2020年，南明河流域水资源生态经济协调指数年均值为1.345，接近最佳协调状态（1.414），水资源经济协调性整体较好。【结论】总体来看，南明河流域人均能值生态足迹、万元GDP和生态赤字呈逐年下降趋势，生态承载力、生态压力和生态经济协调指数呈现上下波动态势，水资源利用整体向好的方面发展。 |

| Abstract: |
| 【Background and Objective】Water resources play a vital role in sustaining life and supporting social and economic development. In the karst regions in southern China, rich precipitation combined with intricate geological structures makes sustainably managing water resources in the region a challenging task. This is further exacerbated by rapid urbanization and industrialization over the past decades. To address these challenges, this paper conducts an in-depth analysis of water resource utilization in these regions by focusing on the Nanming River basin in the Guizhou Plateau.【Method】The analysis was based on the ecological footprint model - a classical method in ecological economics, and the energy ecological footprint model based on energy flow - the latest advancement in this field. Using data measured from 2010 to 2020 on water consumption and supply, we systematically analyzed the changes in water ecological footprint, ecological carrying capacity, ecological deficit, and ecological pressure in the region.【Result】From 2010 to 2020, the annual average ecological footprint of water resources and energy in the studied region was 1.08 hm2 per capita, while the annual average ecological carrying capacity was 0.562 hm2 per capita. Although there was an ecological deficit in water resources, the deficit showed a declining trend over the past 10 years. The annual average ecological pressure index of water resources in the region was 2.004, indicating a sub-security state but remaining within a safe range for such ecosystems. The average ecological and economic coordination index of water resources in the region was 1.345 over the past decade, close to the optimal coordination state which is 1.414.【Conclusion】Our study underscores a positive trajectory in water resource management in the Nanming River basin. Energy ecological footprint per capita, thousand-yuan- GDP and ecological deficit in the basin show declining trends, while ecological carrying capacity, ecological pressure, and ecological economic coordination index exhibit fluctuating patterns. These findings can help sustainable utilization of water resources in the studied region. |
