Extended TODIM‐PROMETHEE II method with hesitant probabilistic information for solving potential risk evaluation problems of water resource carrying capacity

Taking Sunan’s water resource carrying capacity as the research object, this article extracted three principal components from thirteen indicators influencing water resources carrying capacity through principal component analysis method. Then bestowing weights to the three components using entropy value method, the composite scores of Sunan’s water resource carrying capacity from 2002 to 2012 could be calculated.The result shows that, with the advancement of Sunan modernization, Sunan’s water resource carrying capacity will face a major test, thus requiring a reasonable and efficient use of water resources and giving full play to potential of water resources.

Water Resource Carrying Capacity

Introduction: As an unconventional natural gas resource, shale gas is the current hot topic in the oil and gas industry. China is rich in shale gas resource, most of which lies in the Southwest Karst Area with its fragile ecological environment. Discussion: The following questions must be studied before exploration thereof: on one hand, shale gas mining requires a lot of water, on the other hand, if the karst region water resources can support shale gas mining over a large area, and if the consequent water/environmental pollution problems will bring more severe challenges to the sustainable development of society and the economy in the southwest karst area, there is a potential conflict requiring a research-based resolution. The water resource carrying capacity is an important measure of the potential sustainable development of a karst region, with its unique geological structure and fragile natural landscape. Therefore, the study of karst water resource carrying capacity is of great significance. Conclusion: This essay is based on Cenggong County, one of the five key shale gas exploration areas in Guizhou at the end of 2012. By calculating the water resource carrying capacity in the studied area with the help of the ecological footprint method, it is concluded that the existing water resources in the studied area can support shale gas exploration. However, shale gas mining will cause a change in the industrial structure within the region. In addition, it has significant effects on the bearing capacity of water resources in the ecological environment.
