摘要
基于资源生态足迹模型和水资源生态承载力模型,利用云南省2005-2020年水资源和社会经济发展相关数据,对云南省水资源可持续利用状况进行评价。结果表明:云南各用水指标中,生产用水占比最高并呈逐年减少趋势,生活用水和生态用水占比较小并呈逐年增大趋势;水资源生态承载力2011年前波动较大且变化规律不明显,2011年后呈缓慢增长状态;水资源生态盈状况良好,水资源压力指数较低,水资源处于可持续利用状态;万元GDP水资源生态足迹呈下降趋势,2005-2011年下降较快,之后几年下降趋势平缓。
Based on the resource ecological footprint model and the water resource ecological carrying capacity model,this study evaluates the sustainable utilization status of water resources in Yunnan Province using relevant data on water resources and socio-economic development from 2005 to 2020.The results show that among the various water use indicators in Yunnan,the proportion of production water is the highest and shows a decreasing trend year by year,while the proportion of domestic water and ecological water is relatively small and shows an increasing trend year by year.The ecological carrying capacity of water resources fluctuated significantly before 2011 and the change pattern was not obvious.After 2011,it showed a slow growth state.The ecological status of water resources is good,the water resource pressure index is low,and water resources are in a sustainable utilization state.The ecological footprint of water resources with a GDP of 10000 yuan shows a downward trend,with a rapid decline from 2005 to 2011,and a gradual decline in the following years.
