The study looked at how water resources in the Guizhou karst mountainous area changed from 2000 to 2012. They used a model to calculate and analyze things like water usage and ecological balance. The results showed that the total water use increased, but per person use was below the national average. Most of the water footprint came from consuming water, and this part increased recently. The value of water resources also rose, but their economic value in relation to gross domestic product went down yearly. The area's water resources usage efficiency was better than the national average, but the capacity to sustainably use water decreased. This means that while water resources were generally enough, the ability to sustainably manage them got weaker over time. The researchers suggested some ideas based on their findings.
