| Abstract: |
| 【Objective】In order to provide an in-depth analysis of water resources utilization in karst areas and to identify the water resources utilization from the relationship between supply and demand of natural resources in order to provide a scientific basis and useful reference for the efficient exploitation and sustainable development of water resources in karst areas.【Methods】Ecological footprint model is one of the classical methods to measure human social resource consumption in ecological economics, and the energy flow-based energy-value ecological footprint model is the latest achievement in this field of research. This study takes the Nanming River basin in typical karst area of Guizhou plateau as an example, and systematically analyzes the changes of water ecological footprint, water ecological carrying capacity, water ecological deficit and ecological pressure in Nanming River basin from 2010 to 2020 based on the energy-value water ecological footprint model.【Results】The results showed that : (1) From 2010 to 2020, the annual average ecological footprint of water resources emergy in Nanming River Basin was 1.080 hm2 per capita, and the annual average ecological carrying capacity of water resources emergy was 0.562 hm2 per capita. The ecological deficit in water resources was obvious, but the deficit showed a downward trend year by year. (2) The annual average value of ecological pressure index of water resources in Nanming River Basin is 2.004, which is in a sub-security state, and the pressure on the ecosystem is within a safe range. (3) In the past 10 years, the annual average value of the ecological and economic coordination index of water resources in the basin has reached 1.345, which is close to the best coordination state (1.414). 【Conclusion】In general, the per capita emergy ecological footprint, ten thousand yuan GDP and ecological deficit of Nanming River Basin showed a downward trend year by year, and the ecological carrying capacity, ecological pressure and ecological economic coordination index showed a fluctuating trend, Water use is generally moving in a positive direction. |
