惠州市水资源生态足迹评价与预测OA

Based on the water resources ecological footprint(WREF)model,combined with five calculation indicators(water resources ecological carrying capacity(WRECC),ecological profit and loss,ecological pressure,sustainability index,and water resources ecological footprint per 10,000 Yuan of GDP),a quantitative analysis and objective evaluation were conducted to evaluate the sustainability of water resource utilization in Huizhou between 2009 and 2023.The GM(1,1)model was used to predict the changes in the water resources ecological footprint(WREF)of the region in the next 5 years(2024 to 2028).The results showed that from 2009 to 2023,the ecological footprint of per capita water resources,per capita industrial water use,and agricultural water use in Huizhou had generally decreased,while the per capita ecological footprint of household water usage and environmental water provisioning had increased in recent years.The WRECC of per capita fluctuated greatly in different years,but the ecological balance of water resources showed a surplus state.The ecological footprint of water resources per 10 thousand of GDP had been decreasing year by year,and the overall ecological pressure on water resources was relatively stable.Water resources developed sustainably,and during the period from 2024 to 2028 the per capita WREF would continue to decrease.
