摘要:

本研究借鉴2030可持续发展目标(SDGs)的评估指标,采用熵值法和层次分析法确定指标权重,利用主成分分析法分析2006—2020年吉尔吉斯斯坦水环境承载力变化趋势,通过向量模法确定了影响吉尔吉斯斯坦水环境承载力的主要影响要素。结果表明:2006—2020年吉尔吉斯斯坦水环境承载力总体呈增强趋势。水环境和社会经济子系统促进水环境承载力持续升高,而水生态和水资源子系统限制水环境承载力。人口密度、用水紧缺度、水体面积、可再生水资源人均占有量是限制水环境承载力的主要影响因素。增加城镇化率、提升用水效率、减少废污水排放量和提高废水处理率是吉尔吉斯斯坦水环境承载力提高的有效途径。

Abstract:

Kyrgyzstan is an important transportation hub for the countries along The Belt and Road Initiative in China, which is rich in mineral resources, has an underdeveloped economy, has frequent human activities, and has relatively weak ecological environmental protection, resulting in major water environmental problems. Drawing on the evaluation indicators of the 2030 Sustainable Development Goals, this study uses the entropy and the analytic hierarchy methods to determine the weights of the indicators, analyzes the change trend of the carrying capacity of the water environment in Kyrgyzstan from 2006 to 2020 using the principal component analysis method, and determines the main influencing factors affecting the carrying capacity of the water environment in Kyrgyzstan using the vector model method. The results show that the carrying capacity of the water environment in Kyrgyzstan from 2006 to 2020 shows an overall enhancement trend. The water environment and socio-economic subsystems promote the continuous increase in the carrying capacity of the water environment, while the water ecology and water resource subsystems limit the carrying capacity of the water environment. Population density, water shortage, water body area, and per capita share of renewable water resources are the main influencing factors limiting the water environment’s carrying capacity. Increasing the rate of urbanization, improving the efficiency of water use, reducing the discharge of wastewater, and increasing the rate of wastewater treatment are effective ways to improve the water environment’s carrying capacity in Kyrgyzstan.
