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之一,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。本研究以贵州高原典型喀斯特区—南明河流域为例,基于能值水资源生态足迹模型,系统分析2010-2020年南明河流域的水生态足迹、水生态承载力、水生态赤字和生态压力等变化情况。【结果】研究结果表明:(1)2010-2020年,南明河流域水资源能值生态足迹年均值为1.080 hm2·人-1,水资源能值生态承载力年均值0.562 hm2 ·人-1,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;(3)近10年来,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:
【Objective】In order to provide an in-depth analysis of water resources utilization in karst areas and to identify the water resources utilization from the relationship between supply and demand of natural resources in order to provide a scientific basis and useful reference for the efficient exploitation and sustainable development of water resources in karst areas.【Methods】Ecological footprint model is one of the classical methods to measure human social resource consumption in ecological economics, and the energy flow-based energy-value ecological footprint model is the latest achievement in this field of research. This study takes the Nanming River basin in typical karst area of Guizhou plateau as an example, and systematically analyzes the changes of water ecological footprint, water ecological carrying capacity, water ecological deficit and ecological pressure in Nanming River basin from 2010 to 2020 based on the energy-value water ecological footprint model.【Results】The results showed that : (1) From 2010 to 2020, the annual average ecological footprint of water resources emergy in Nanming River Basin was 1.080 hm2 per capita, and the annual average ecological carrying capacity of water resources emergy was 0.562 hm2 per capita. The ecological deficit in water resources was obvious, but the deficit showed a downward trend year by year. (2) The annual average value of ecological pressure index of water resources in Nanming River Basin is 2.004, which is in a sub-security state, and the pressure on the ecosystem is within a safe range. (3) In the past 10 years, the annual average value of the ecological and economic coordination index of water resources in the basin has reached 1.345, which is close to the best coordination state (1.414). 【Conclusion】In general, the per capita emergy ecological footprint, ten thousand yuan GDP and ecological deficit of Nanming River Basin showed a downward trend year by year, and the ecological carrying capacity, ecological pressure and ecological economic coordination index showed a fluctuating trend, Water use is generally moving in a positive direction.
