基于生态足迹理论的厦门市水资源可持续利用分析

Analysis of the Water Resources Sustainable Utilization in Xiamen City Based on Ecological Footprint Theory

采用生态足迹法计算2012—2019年厦门市水资源生态足迹和生态承载力,并引入万元GDP水资源生态足迹、生态压力指数和可持续指数对厦门市水资源可持续利用状态进行分析。结果表明,2012—2019年厦门市人均水资源生态足迹变化不大,平均值0.272 hm^(2);人均水资源生态承载力总体下降,从0.548 hm^(2)减少到0.346 hm^(2),下降了36.9%;水资源在2017和2018年出现生态赤字;万元GDP水资源生态足迹明显降低,水资源利用总体上处于弱可持续状态。

The water resources ecological footprint and ecological carrying capacity in Xiamen from 2012 to 2019 were calculated by using ecological footprint method.The water resources ecological footprint per ten-thousand-yuan GDP,ecological pressure index and sustainable index were introduced to analyze the sustainable utilization of water resources in Xiamen.The results showed that the per capita water resources ecological footprint did not change significantly from 2012 to 2019,with an average value of 0.272 hm^(2).The per capita water resources carrying capacity decreased from 0.548 hm^(2) to 0.346 hm^(2),a decrease of 36.9%.There was an ecological deficit in water resources in Xiamen in 2017 and 2018.The water resources ecological footprint per ten-thousand-yuan GDP decreased significantly.The utilization of water resources in Xiamen was in a weak sustainable state.
