- Abstract:
- Water resources ecological footprint is one of the research hotspots in the sustainable development and utilization of water resources. The current research focuses on the study of the ecological footprint of water resources at the regional scale. Optimizing the ecological footprint model of water resources and exploring the problem of scale correlation are necessary for the sustainable development of regional water resources. Based on statistical data and grid data, the changes in the development and utilization of water resources in Beijing from 2005 to 2018 were explored at the city and grid scales by combining with the emergy theory of ecological disciplines on the basis of the traditional water resources ecological footprint. The results show that:(1)from 2005 to 2018, the annual average value of Beijing's water resources emergy ecological footprint was 0.35 hm2 per capita, and the annual average value of water resources emergy ecological carrying capacity was 0.05 hm2 per capita; the ecological deficit was obvious;(2)Beijing has been in a state of ecological insecurity of water resources for many years; the average annual value of water ecological footprint intensity is 7.37, and the annual average value of water resources ecological and economic coordination index is only 1.13; the coordination between water resources ecosystem and economic development is poor;(3)the spatial distribution of water resources development and utilization is uneven, the ecological deficit of water resources in the central urban area is serious, and the ecological pressure of water resources is above 30; the ecological pressure on the surrounding urban areas has eased, and Pinggu District is the only ecological safety region in Beijing. The situation of water resources ecological security in Beijing is relatively severe. It is necessary to restrict population, adjust industrial structure, strengthen publicity on water conservation, and improve water conservation efficiency.
