基于生态足迹和SD模型的山东省水资源可持续利用评价
Evaluation of Water Resource Sustainable Utilization in Shandong Province Based on Ecological Footprint and SD Model
摘要
Abstract
The ecological footprint and ecological carrying capacity of water resources are of key directive significance for the balance between supply and demand of regional water resources and are increasingly important in the construction of ecological civilization and sustainable water resource utilization.However,existing research lacks accounting and evaluation of the ecological footprint of water resources in Shandong Province.Based on the ecological footprint model of water resources and the system dynamic model of water supply and demand in Shandong Province,the ecological footprint and ecological carrying capacity of water resources in Shandong Province from 2001 to 2022 are calculated and evaluated.The results show that:① From 2001 to 2022,the ecological footprint of water resources in Shandong Province showed a fluctuating downward trend,with the average per capita ecological footprint and the average per capita ecological carrying capacity of water resources being 0.379 hm2/person and 0.106 hm2/person,respectively,showing a slow downward trend.As a result,the per capita ecological profit and loss of water resources were both negative(with an average of-0.2731 hm2/person),indicating that there were ecological losses of water resources in all years.Water resources in Shandong Province have always been in an unsustainable state of utilization,enduring significant ecological losses of water resources.②From 2001 to 2022,the ecological pressure index of water resources in Shandong Province was greater than 1 and showed an upward trend,with an average value of 3.581.The ecological and economic coordination index of water resources had little fluctuation,with an average value of 1.232.The ecological footprint intensity of water resources showed a significant downward trend,with an average value of0.143 hm2/104 RMB and a decrease of up to 90.9%.Shandong Province suffered from significant ecological pressure on water resources from 2001 to 2022,and water resources were in an unsafe state of utilization.The ecological and economic coordination of water resources was good,but there was still a gap from the optimal ecological and economic coordination of 1.414.It is necessary to further strengthen the ecological and economic coordination of water resources in Shandong Province,and the efficiency of water resource utilization has been greatly improved.③Shandong Province needs to invest a lot of effort in promoting water-saving facilities,adopting water-saving cultivation techniques,and improving water efficiency.In terms of domestic water use,as the population is constantly growing,it is necessary to increase efforts in cultivating public awareness of water-saving,vigorously promoting the protection of existing water resources,and popularizing water-saving measures in the whole society.Only by making the awareness and behavior of water-saving deeply rooted in people's hearts can we better and more effectively promote the sustainable use of regional water关键词
