基于生态足迹法的昆明市2010—2021年水资源可持续利用分析

Analysis of Sustainable Utilization of Water Resources in Kunming City from 2010 to 2021 Based on Ecological Footprint Method

为更好地了解昆明市水资源生态安全状况,本文选取2010—2021年昆明市水资源的相关数据,运用水资源生态足迹模型,对昆明市水资源的可持续利用状况进行分析评价。研究结果表明:昆明市水资源处于生态赤字状态,人均水资源生态足迹变幅较小,人均水资源承载力的起伏变化较为明显,且随降水量变化而变化,万元GDP水资源生态足迹明显降低,水资源生态压力大,呈不可持续状态,开发潜力很小。研究结果可以为昆明市水资源可持续性研究提供一定的依据和参考。

In order to better understand the ecological security status of water resources in Kunming City,this paper selects relevant data on water resources in Kunming City from 2010 to 2021 and uses the water resources ecological footprint model to analyze and evaluate the sustainable utilization of water resources in Kunming City.The research results indicate that the water resources of Kunming City are in an ecological deficit state,with a relatively small fluctuation in per capita water resources ecological footprint,noticeable fluctuations in per capita water resources carrying capacity,which vary with changes in precipitation,a significant decrease in the ecological footprint of water resources per 10,000 GDP,and a high ecological pressure on water resources,indicating an unsustainable state with little development potential.This study can provide a certain basis and reference for the research on the sustainability of water resources in Kunming City.
